| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| GRADIENTE | TF2140 | The TV turns on normally with a black band on the right side of the screen moving the image to the left side | The cause of the defect was the capacitor c918 close to the horizontal output transistor | After replacing it, the TV started working normally again. | AssisTec Manari/PE |
| GRADIENTE | TF2140 | TV with a symptom that looked like it had a burnt horizontal output, but when carrying out tests, it was clear that tsound was a blown capacitor. (c709) | A capacitor (c709) literally burned | In my case, I removed it and turned on the TV, but of course you have to check the entire power supply and horizontal stage | Adriano SB |
| GRADIENTE | TF2140 | Burning the power supply + vertical resistor | 47k ceramic capacitor shorted near the stv9302 ci | Replace | |
| GRADIENTE | TF2140 | Does not turn on only on stand-by | Remove the glue near the power supply transformer and clean the components, change the 1000uf /16v cap | warley cesar | |
| GRADIENTE | TF2140 | Doesn't start | Energy left | Replace d 909 | eletronica alsat itajobi/sp |
| TV GRADIENTE | TF2140 | This TV was inoperative, I found the transistor p9nk90 burst, I put another one in and I also found two resistors that work with it open, I put it in the series and it gives several rapid oscillations but I can't leave it because it overheats and shorts out. | Problem was solved I found no. 913 of 10 mega open and as incredible as it is the fet I bought were three not even 1 was any good I got an original from Philips and it was great it doesn't even heat up | BF.COLATINO | |
