Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | LN32D550K7G | Dark picture on the right side/ backlight lighting but without power | PFC power supply was not bending only 167v | In this case tsound were altered resistors (100ohm less than it should) in the resistor bank that picks up the CP8035 capacitor (450V), more specifically RB803-806 and RP809-812 Remove and measure outside PCB | micropcb |
| TCL | 43S615 | Don't turn on | Does not turn on and Staby's light does not light up | Disconnect the Flat cable from the Wifi module, if the TV turns on or lights the standby light, please check the SMD capacitor that is side of the WiFi plate connector. | ROBERVAL SILVA |
| ONEAL | OCM2910 | Sometimes it gets a snap and is without sound | Signal Input Decipping Capacitors of the audio output | I had replaced CI, but went back to defect, then discovered a small escape in the capacitor of pin 12, replaced the pin 11 also through the doubts, they are 1uf | Davi.sls |
| SAMSUNG | CL29K40MQ | Lights only half of the tube | Request solution | Renato | |
| LG | 49SM8000 NANOCELL 49UM7300 49UM7500 49UN | Adapt 49sm8000 screen on line 49um or 49un | If you prefer you can also use the line one or un board on 49sm8000 | PDF: External Link... | World TV - Sorocaba |
| PHILCO | D26F 053801028 | No+connect | Don't Luga | Paulo | |
| SONY | KD-49X705F | 4 | flashing 4 times ch. t con in the short CPC.1105 left side, fuse inter plate F.1000 5A | resolved | eletronica fama |
| PHILCO | PTV43VA4REGB | Does not start, in infinite loop | TV Tsound is no way to restore by Pen Drive, restoration in an original that has behind, is a reset button near the entrances, pressing for 10 ~ 15 seconds. | AXCELL | |
| TCL | 32S5400 | Don't turn on | TV does not turn on, no stand by | In my case, CA2 (capacitor) was removed next to CI UA1 | AXCELL |
| HQ | HQSTV55 HK.T.RT2831P838 | Warming and burning the QW2 in minutes | The cause is the circuit prior to the power supply cap. | TRW2 and 4 TAKE 2 TRANSFORMERS IN ONE, JAMPING DW5, remove the RW15.16 or 17. Remove QW2.R | GDP2 Macajuba |
| H-BUSTER | HBTV-32L05HD | Alloy and lock | DC/DC power supplys Main | CA804, 815, 712 | Cesar |
| TV TCL | 50P635 Não sei | LED current | LED replace | replace SMD 830 resistor that comes out pin 2 U601, put a 56k, the original and 45 or 46k, tension redeemed from 140 to 120 volts. | Alextronica |
| TV SEMP TCL | 50P635 | LED current | LED current | replace resctor 830 near 601, it is 44 or 45k, I put a 56k was top, it has 140 volts fell to 120. | Alextronica |
| PHILCO | PH32D LCD | Don't turn on, just red LED | R383 Put on one of 220r | Rodrigo cofferi | |
| SEMP TCL | 50P635 | Reduce LED Bus Tence | The voltage 141,1V above LED bar are 21 LEDs 6V adding will give 126v ob3356QP in pin 2 IC, resistor R830 he 43k 0603, remove put another in place 120k 0603 the tonte falls 123.7V | Solved problem, not to return TV to technical | André |
| PHILCO | PTV55G52R2C | LED current reduction | Remove 2 1R SMD resistors and remove the SMD RFA31 (larger) resistor and place another 0.56R in series | reginaldo moronte,eletronica junior caldas novas | |
| SAMSUNG | DISPLAY DUPLICADO E TREMULO | Duplicate Display and Timulus | Placa Vcom | ||
| PHILIPS | SW 986 SM | Protection acting intermittently, generating flaws by arming, or not setting up the refe of the speaker | R513/517 resistor terminals with weld oxidized terminals, generating bad contact. | Remove resistors, sand the terminals and resonoliate again | Assolini BR |
| TV LG | 50PN4500 sz.awzlljz | It turns on, the logo appears and then shuts down. When it is heated with a blower over the Q356, it connects normally. the | Q359 with leakage from the collector/issuer. Hugs to all. | Derci Joaquim | |
| PANASONIC | TC-L32U5B | Normal alloy, flashes lamps | replace in the inverter plate, oscillates the voltage and flashes lamps | In my case, the resistor R313 removed. Near the ci, with a finger on the components it did not blink | Servitron |
