Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SAMSUNG | LN26B450C4M | It doesn't turn on, the LED lights up, keeps blinking and it takes a long time for it to work. This defect is misleading, because as we know, if we remove the cable that comes from the main board to the power supply and connect it to the power supply, the power supply, if it is good, allows the lamps to turn on, and this happened, so I suspected the main board, but the power supply persisted. I found the capa cm852 with low capacitance, 1200uf/10v, it was 600uf | Cm852 sold out. | Cm852 replace | MIGUELTV |
| H-BUSTER | HBTV-4203FD | Doesn't start. led off | 47ufx35v electrolytics, close to the power supply ci | Eletrônica Cecé. Brumadinho MG | |
| AOC | LE39S5970 | Getting very hot booster circuit that powers the LEDs | Current that goes to the LEDs is very high, which increases the risk of burning the power supply circuits, as well as the LEDs themselves | Replace the value of the booster mosfet power supply power resistor, place one from 0r27 to 0r33 | davi.sls |
| AOC | LC32W053 | LED off in forced connection has 5v 12v 24v but the LED is off | C 953 330/16v had 310mf on the power supply board | It was a tip from this channel | gdp2 |
| PHILCO | PH14C 20C | Sound 0 mute 1 full volume. | After copying several memories, it can only be resolved by changing the data. | Menu 6483, mute, up to m2, setup celect to 1, mute up to m6, v. max from 46 to 63, mute m9, balance from off to on. sir stand by | George Pontes |
| PHILIPS | 43PFG5000/78 | The LEDs turn on but tsound is no image | C109 c120 on the display ruler | Adeilton | |
| PHILCO | TP2920 | It connects with the magnetized tube and has a colored wheel in the middle of the screen. | Rl1 | Replace the rl1 relay | Sinailson furtado |
| PHILCO | TP2920 | Turns on with retrace lines at the top of the screen and the vertical closes and the TV turns off. | C1 | Replace o capacitor c1 100μF25v | Sinailson furtado |
| SEMP TOSHIBA | TV2134(C)SL SK11 | Tv with green image with retrace lines | Change the tube (kinescope) | Marcleo | |
| BRASTEMP | BMS45 | Abre a porta turns lawn | Front plate | Q7 a1015 replace the same | Tec Center |
| LG | 21SA1RL CW81B | E/w | Check q405(k2941), r455(10k), l401 l401, zd403, d402 and d404 | Replace burned components after check | Prem Shankar Singh |
| AOC | LE39S5970 | Don't care, dead | Faulty power supply, blown primary components | Q9101 13a 650v, r9101 0r22 3w, u9101 ld7531, r9109 1k, c9111 100n, c9108 220p, r9106 47r, d9102 1n4148, r9104 22r | davi.sls |
| SONY | FST-ZX80D | Turns on, eject appears on the display and turns off | Turns on eject appears on the display then turns off, deck motor keeps spinning non-stop 2 open photo diode not sold in electronics stores, replace with photo sensitive diode and equal to a 3mm LED, it worked and didn't turn off | Defect resolved | Andre |
| SONY | HCD-ZX80D | No audio on outputs | Normal power on with no audio at the outputs, the 2 stk402-240m and stk403-070 are all good defect ic101 - m61529fp change and also test all the electrolytic capacitors around this ic some with problem, resolved the audio at the outputs worked | Defect resolved | Carlos |
| SAMSUNG | UN32J4290 | Does not turn on, completely inoperative, external power supply with 19 volts normal. | In this case, heating was observed on the plate in the upper right corner. | Short in smd ceramic capacitor c17 next to the ic206 regulator, just replace it and the TV worked normally. | ToniTec |
| PHILCO | PH21USA1 | Low noise at the power supply, all low power supplys, +b 60 and a few v. does not start. | R 553 from 5k6 altered for 13k .trimpot 2k aberto | Replace these components. | J B Eletron |
| CCE | TV-2118USP/AV FBT STD | Expanded image | D409 eo q405 | Replace d409 and q405 if you don't have transistor q405, replace this transistor with bf422. Put it the other way around and that's it, the TV will work normally. The BF422 Eli transistor is used in the RGB of Philips TVs. God be praised! | Sinailson furtado |
| LG | 21FJ8RL | Tv arms and disarms | Q16 e r301 | Replace it with another and run to another | Antonio Carlos (Eletrônica Renascer) |
| TOSHIBA | U18 | Turns off the LED and the horizontal one heats up a lot and does not generate protection. | Short vertical | Maranguape | franciscoferreira |
| SEMP | TV2122(O) FS U19 | White lines at the top of the screen | C308 of 100mf by 35v near the vertical ci | Replace of the same | AssisTec |
