3|Pag e, , LCD LED Panel Failure and Cure, COLLECTION OF TRICKS & HOW-LED LCD TV SERVICE FROM, VARIOUS SOURCES RELIABLE TECHNICIANs, , Here is I reveal a big secrete of Panel repairing for you and a Chance to earn big money, from it, Some LCD panel failures could possibly mistake for T-Con board issues. Other, than damage to the LCD glass, most panel failures are isolated to a particular area of the, screen. Since the T-Con disperses the pixel data to groups of line and column drive IC’s, situated on the outer edges of the panel, it is unlikely that more than one of these IC’s, would fail at the same time. Multiple columns of struck on or stuck off pixels are therefore, more likely to be the fault of the T-Con circuits. The same applies to a single row, of lit or unlit pixels. The T-Con simply cannot cut out a single line of information., , L.C.D L.E.D T.V Panels Connection and Voltages Understanding, , Here we talking about the main voltages and pin connection of L.C.D and L.E.D T.Vs, Panels, every technician should know where to test and how to check voltages of each, connection as they mention in Service Manual or schematic diagram or at least you, should know the basic working voltages., Connection Name, 1.

14 | P a g e, , Panel Cut-Circumcision, LED, LED panel damage of this kind is one of the damage that is often experienced. Although in a different shape or position, such as partial or one-third of the panel, but the, source of the damage is still almost the same. We can try to modify the source voltage, supply part (output voltage I.c scan MAX 17108) in order to supply voltage could be, close to normal, because we know that this kind of panel does not have the FPC to Raw, driver (scan driver)., , Table for understanding, , 1. Unloading the entire casing panels to ensure that there is no path FPC (column) was burned., 2. Check all output voltages power Ic TCON correction when there were fewer, than all system voltages., 3.

Normal remote control switch machine, indicating the control, part of the motherboard is working properly. Focusing on the logic board on the check, Logic board mainly by the format converter and DC/DC converter circuit. Because the, screen is not lit, so focus on DC/DC converter circuit check, for easy maintenance, a, brief analysis at the circuit control process., VCC-PANEL enter the UP1, 21, 22 feet, converted through a chip from the 18th pin, (SWB) UP5 output 2.5V voltage regulators get 1.8V provides format conversion chip, supply. UP1 11th foot (DRN) DP7, C227, UP1 foot booster circuit consisting of an output, voltage of around -5.6V VGL provides negative pressure for driving power.2.5V UP1, chip detected after work, LP7, LP2, DP2, DP6, UP1 feet (SW) 5 pin (SW) internal circuit, voltage boosting circuit start? Work? the output voltage of 16V, UP1 feet (GD) provides, an open signal for QP1 and QP2, 16V over QP1,QP2 VDA voltage driving circuit for, power supply., When the above circuit normally work, VAAP vetted by DP5, CP18, UP1 feet (DRP) consisting of internal voltage boosting circuit was working properly, and got VGHP by, RP21 current voltage, VGHP QP8 output voltage of 22V about VGH provide power for, the drive., From the above analysis we can see that when the circuit starts working normally, strictly temporal relationship exists. This timing check voltage of all found only 10.5V, VGHP voltage, normal for 19.5V.VGH voltage is 0V, normally should be 18V. There is a, clear problem is caused by VGHP voltage is not boosting properly., , The UP1 10th pin voltage is 0V, normally pin 10 should be able to detect the 2.25V of, DC voltage, AC test 5V AC voltages, but measuring AC and DC voltage not detected., Measurement of resistance the feet on the ground, nothing suspected UP1 foot internal, damage, troubleshooting after replacement., , 19, , ImagineX ElectronicS

21 | P a g e, , Formation because the failure analysis VGHP voltage is provided to gate-level of high, potential, which opens the gate-level voltage, when LCD LCD screen loses the voltage, will cause internal TFT LCD LCD screen is not working properly with this type of fault., Conclusion: logic board mainly consists of a format converter and DC/DC converter, circuit. By the process of analyzing and removing these two faults, we can see that most, of the fault lies with the logic board DC/DC converter circuit. For the maintenance of, this portion of the circuit, as far as the structure of its circuits are not difficult to understand, the key point is to familiarize yourself with its timing control and 5 large voltage, DC/DC converter circuit. Also needed a mention of is, in we of maintenance practice exploration in the found, logic board Shang by with of components in market is completely can procurement to of, and price very low, on above two a fault of maintenance, its, maintenance cost are insufficient 30 USD, only for Board level maintenance price of, one-tenth, so for LCD TV logic board of maintenance not only is technology level of development and beyond, and also is more with Future of., , 21, , ImagineX ElectronicS

During operation, the image becomes “still” and after turning to, white, disappearing. In both above cases the display is sensitive when torsion it, close to, moment the image appear (first case ) or “still” ( second case ) ., The cause of above symptoms is the failure of one of contacts between the first IC-FPCB in, the upper-left corner of display and upper long and narrow PCB of display. Unlike the rest of, FPCBs with drivers for vertical lines , this one have some circuits that just passing through it, , to some circuits over panel glass , and through these , to the first of three drivers for H-lines, on left side of panel glass ., The access to “long-and-narrow” PCB in the upper part of display, and to FPCBs is only, possible after removing of front metal frame of LCD display (fixed in 10 screws) ., The T-Con board must also be removed., The repair solution described below requires good skills, so please don’t do it if, 26, , ImagineX ElectronicS

27 | P a g e, , you haven’t done operations of similar complexity. In pictures P01, P04, P05, P06 is, described the correspondence between pads on first upper H-driver (please note that, pads are accessible below H-driver FPCB when LCD display is on the table) ., Attention! All of these pads (numbered in P01 from 1 to 15) are covered with a green flexible paint. To detect the interrupted circuit, please scratch gently the paint on the center of, each pad (P03.jpg) to can contact them with the tester of multi-meter., I recommend using for scratch a new surgical scalpel (curved, not straight). It is very important that the scalpel to be a new one, not a blunt one. Attention!!! Be careful when scratch, center of pads; don’t touch with scalpel the thin circuits near the pads., For easily access to pads and to avoid the dust and foreign materials to enter between, backlight and LCD-panel, carefully and gently lift up the driver FPCB and fix it with adhesive tape in vertical position to don’t excessive stress the FPCB, but enough to can access the, pads with scalpel, tester and soldering iron. If you consider unsafe lifting of driver FPCB, is, better to lift the whole LCD-panel (glass) and put it “up side down “ , but take care of any, dust and foreign object to avoid dirty the display . Take care also of driver FPCBs between, the long upper PCB and display, don’t excessive stress them., The most frequent circuit found interrupted is that one corresponding to pad numbered 10, ( P01.jpg ) and indicated in P03D.jpg ., For easily measurement, please measure the continuity of this circuit to the pad numbered, 10 in P06.jpg, near the connector to T-Con board., You can read below the normal resistance values for all circuits (all are so big values, because of thin circuits on the glass) ., There are also the normal voltage value that can be measured during function and the, voltage drop on each circuit (where is not specified, is below 0.1mV), Please note that pads numbered with 11, 12, 14 are not connected, so don’t, measure them., st, , 1 -> 1 line (-5.5V), 2 -> 13Ω ( -5.51V , 7mV ), 3 -> 17Ω ( +21V , 12mV ), 4 -> 13Ω ( -5.51V , 8mV ), 5 -> 50Ω ( 3.29V , 4.1mV ), 6 -> 61Ω ( GND , 3.5mV ), 7 -> 91Ω ( 3.3V ), 8 -> 84Ω ( 917mV ), 9 -> 84Ω ( 1.73V ), 10 -> 84Ω, 13>20Ω(+5.37V), 15 -> 84Ω ( 3.3V), 27, , ImagineX ElectronicS

Please use normal soldering alloy (40/60) not Lead-free ., All these operations must be done with the display disconnected (and completely isolated, from any metal part of table), using the antistatic bracelet connected to soldering iron, ground contact., Please solder an end of prepared thin wire to pad 10 (P08.jpg, P09.jpg) .Release the driver, FPCB by carefully and gently unstuck of adhesive tape. Don’t excessive stress the FPCB, .Prepare a 5mm strip of adhesive tape and stick the FPCB ( P10.jpg ) .Position carefully the, wire ( P11.jpg ) , fixing it from place to place with thin ( 3mm) strips of adhesive tape .Find, the crossing hole numbered 10 in P04.jpg , P05.jpg and tin it with soldering iron ., If you consider difficult to use this point to solder the wire, you can use the pad near the, T-Con connector (P06.jpg) – but you must use a longer wire. You also must take care to, isolate it along its route., Solder the end of wire on prepared cross hole ( P13.jpg , P14.jpg , P15.jpg ) - or to above, specified point , and after , fix the rest of wire (P13.jpg ) ., In case you don’t find at first measurement an evident interruption of circuit corresponding to pad 10, before solder the wire to cross hole connect again the ohmmeter, between end of wire and pad 10 near connector, and gently touch the side of upper, driver FPCB (the side near the display side) and look for a resistance variation.

42 | P a g e, , T-Con board AS-15HG problem, , DIAGNOSING A FAILED T'CON BOARD, All video inputs received by the video process circuits are handled on a frame-byframe basis. The video frames are converted and scaled to 8 to 10 bit RGB information., It is virtually impossible for the video process circuit to cause a problem on a specific, area of the screen. Failures on this board usually appear as distortions, color level, shifts, video level shifts or noise that involves the entire picture. The T-Con can generate symptoms that appear to be video process related, but the video process circuit, cannot produce the symptoms of a failed T-Con board circuit., , T'CON FAILURES, Failures in the timing control circuits of the T-con can produce symptoms of absolutely no video or generate lines and patterns that usually cover all or a substantial part of, the screen. Determining if the T-Con is the cause of a ‘No Video’ condition is a bit more, difficult since there are no indications on the screen to analyze. Negative picture also, comes from bad Gamma correction i.c of AS-15F, many of the Sony TV models of the last, few years will detect a T-Con that has completely failed. The communications data between the video process circuits and the T-Con will cease to communicate, if the T-Con, fails completely. This will cause the TV to shut down and display a diagnostic code, in42, , ImagineX ElectronicS

44 | P a g e, , Samsung T-CON Problem, , 12v Missing, , Samsung T-con Faulty SMD, , It is usually safe to assume that the problem lies on the T-Con board, if the replacement, video board dos not give a solution to the problem since it is highly unlikely that a replacement board with the same failure was received. One trick to check most T-Cons, for functionality is to loosen the LVDS connector at the T-Con while unit is turned ON., Handle the LVDS connector with care and be certain to fully release the lock tabs. Gently rock the cable in and out of the connector while observing the screen for any response., Depending on the chassis, the symptoms of the screen ma be gentle white flashes, intermittent colored lines, or a screen full of random patterns. The idea at this point is to, provoke some kind of response on the screen. Another helpful procedure is to rapidly, heat and/cool the T-Con with a hot air devices or circuit coolant and watch for patterns, appear on the screen, Here we show some different voltages and signals of Samsung, BN96-07611C T-Con board for understanding when you test t-con boards you should, know the basic voltages., , 44, , ImagineX ElectronicS

50 | P a g e, , Understanding of LVDS cable failures, , Although the problem with LVDS cable or connectors can generate symptoms of T-Con, failures this usually tends to be intermittent and wiggling of the connectors will usually, provoke a change in the symptom on the screen. LVDS cable and connectors have became rather robust over the past few years. Technicians who damage them cause most, problems and this is generally quite oblivious upon close examination., LVDS CABLE, , T-CON REPLACEMENT, In many instances, replacement of the T-Con board will be relatively straight forward., In some case, the other boards may have to be loosened or removed to allow access to, the mounting screws and clearance to remove the T-Con board. The issue of most concern is keeping track of the heat transfer pads, stand offs and insulators. The T-Con is, heavily shielded and it is ease to have one or more of these components accidentally fall, out of the assembly when removing. T-Con assemblies that use multiple heat transfer, pads must be removed slowly and every attempt must be made to keep the shield and, circuit board together as they are removed from the unit. Check for any service bulletins pertaining to the model and panel design that contain the subject lie of T-Con heat, transfer pad locations’ for pictures to show the proper location of these components., This site itself has covered disassembly procedure to some model LCD TVs, here. Pull, 50, , ImagineX ElectronicS

It will make search the easily., Cable Fault, , Remove the screw from the LVDS cable ground strap so the cable can be moved away., Unplug the connector to inverter board and remove harness from the retainer. Remove, all screws securing the board sub-chassis to the panel. Pull the top of the board toward, you and downward to allow access to the bottom screws securing T-Con. The position, of screws and disassembly method may vary set to set., Carefully unpeel the conductive tape from the top bracket taking care not to tear, them. Leave the tape attacked to the T-Con shield. Remove the top bracket covering, the gate and source driver components. This will allow access to the upper flat cable, connectors, if any. Carefully lift the locking tabs securing the flat cables. Leave the fat, cables attached to the T-Con and shield assay. The T-Con board will have an insulating, pad between it and the LCD panel that will cause the board to stick. Not much effort is, required to release it. The goal at this point is to remove the board and shield together, so as to avoid dropping heat transfer pads and insulators located between the front of, the board and the shield. If successful, both components should stay together as insulated. Note the spaces mounted on the backside of the board. These will need to be, transferred to the replacement board. Lift the circuit board upward slowly while observing the location of the heat transfer and insulating pads. In most cases the heat, transfer pad will remain attached to their appropriate ICs and the insulating pads will, be struck to the shield. If anything falls off, use the instruction to return them to their, proper position. Transfer all heat and insulating pads along with the flat cables to the, replacement board. Once the components have been transferred to the front of the circuit board, attach the shield and flip the assembly. Transfer any spacers or insulating, pads to the replacement bard. Temporarily secure the T-Con board to the shield with, electrical tape. This helps in preventing movements of the circuit bard while installing, the assembly back into the LCD panel. Once the T-Con assay is secured to the panel, insert and lock the flat cables., 51, , ImagineX ElectronicS

With his spontaneous, recovery in the operation after the closure of duplication between the signals obtained, STV and STV_R panel and again becomes defective. In my case (almost immediately revealed when running) observed the effect of "running footage." A colleague came repeated two weeks later - "the cold is no ISO first 15 minutes."
