Samsung PN43H4000 Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | PN43H4000 | picture, blurred, negative, drizzle vs normal voltages, va and vsc | Q 5010 (sun 0550) with leakage plate and its | replace | Hndrsn |
| SAMSUNG | PN43H4000 | Does not turn on, voltages appear and drops | C5802, (22uF x 50v) with low esr | Stiltec | |
| SAMSUNG | PN43H4000AG | After a while, the voltage from you disappears, leaving only the Audio. | Problem with q5014 and d5057 (bad or fake components) | Exchanging them for original components. | DANGRA ELETRÔNICA SÃO PAULO |
| SAMSUNG | PN43H4000AG | After maintenance on the system, the TV works normally, but after a short time the image disappears, leaving only the Audio | Q5014 and d5057 have problems or false components. | Replace components q5014 and 5057 with good components. | DANGRA ELETRÔNICA SÃO PAULO |
| SAMSUNG | PN43H4000 | Dark screen or drizzle on characters, audio and normal voltages, only go with 12v. | Open zener diode, zda 852 close to the qa852 transistor. Note: the diode is underneath the board. ps, the diode was taken from another board, I don't know the voltage. | After the replace, the image returned to normal. | George Pontes |
| SAMSUNG | PN43H4000 | Mirror image | It came without working, just the LED was blinking. | Corrective maintenance was carried out on the y-sus board (replacement of the IGBTS, diode, capacitors...) when it worked, the image came back mirrored with some black dots in the image. (solution was a loose pin of transistor q5002 under the glue, on the top of the board) | Max Matipó |
| SAMSUNG | PN43H4000 | Doesn't even turn on the power LED | 3.3v regulator short on main board | Replace ic201 near the connector that comes from the power supply | cleber lima rs |
| SAMSUNG | PN43H4000AG | Does not turn on and the standby LED is off | Change the photocouplers on the power supply board | D.a redetech | |
| SAMSUNG | PN43H4000 | Every stop, not even the LED lit up | Check all the jumpers because in my case they were all broken and also check under the heatsink as tsound are some hidden tsound ok good luck that was my case I fixed it and went to dim dim | eletronica publisom | |
| SAMSUNG | PN43H4000AG | TV doesn't turn on, LED STBY is off. | Board short, replace main board. | Bga micro controller short | RNSPTEC |
| SAMSUNG | PN43H4000AG | TV does not turn on, the LED blinks 6 times, voltages between STBY and power on are normal. | Defective main board. | Replace main board micro bga failure. | RNSPTEC |
| SAMSUNG | PN43H4000AG | Tsound is no VA and VS voltage | Icm851 (tl 431 -smd) | Icm851 | Tibúrcio |
| SAMSUNG | PN43H4000AG | TV does not turn on or come on stand by, | Stand by voltage giving 1.2 volts | Resolder all the components on the power supply board including the SMD ones and, as a precaution, replace the photo couplers since Samsung has had problems with photo couplers. | Eletrônica Santista |
| SAMSUNG | PN43H4000AG | Standby LED on, TV won't turn on | It says b5v due to a short on the line diode d202 on the main board shorted, replace the TV and it works normally again | Junior | |
| SAMSUNG | PN43H4000 | After changing the Y-sus TV repair kit, the screen turns off after being turned on for a while. | Poor quality transistor q5014 (fgd4536) triggering protection. | If you can't find good quality, adapt a normal 30f126 using a small heatsink. | mfelipe |
