| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| GRADIENTE | GT2022 | Doesn't turn on, keeps beeping | Fly-back 155-177j shorted, output h. - 1677 shorted, r-10k burned | Replace fly-back, exit h. and r- 10k, after subs. everything ok | WILSON - SR |
| GRADIENTE | GT2022 | Defect does not turn on without +b and protecting | Cause: capacitor 823 of 471 x2kv shorted | klein | |
| GRADIENTE | GT2022 | Turns on, tsound is sound but no image, filament is off | Voltage everything normal, filament off | After chipping a lot, it was just the fr401 | eletronica vieceli |
| GRADIENTE | GT2022 | Does not turn on (horizontal does not start), all voltages are +b | Ic 804 lm7812 defective | Replace dop and money in your pocket | Paulo Sertel Itararé SP |
| GRADIENTE | GT2022 | TV does not arm, the power supply has 160v in the capacitor | As incredible as it may seem, the ignition key had one side open. | fio | |
| GRADIENTE | GT2022 | Bad tune or losing tune | Changing the three capacitors inside the varicap c325-047uf/50v c318-2.2uf/50v c316-47uf/16v solved the problem. | Sandro .T. Grachet | |
| TV GRADIENTE | GT2022 | This TV has several shadow stripes over the image in a horizontal direction, it starts in the left corner and becomes faint as it reaches the middle of the tube. | Replaced the 4.7 x 250 180v capacitor and resolved the defect. | BF.COLATINO | |
| GRADIENTE | GT2022 | Stretched image with a vertical line in the middle | 3r9 1w resistor fr301 altered 60r | Replace | Eletroclaudio Aguas Belas PE |
| GRADIENTE | GT2022 | The TV doesn't turn on and it keeps chirping like it's burnt out. | The TV was making noises as if the bu was bad, when it was measured in place, it was actually measuring directly, but when I took it out it was fine. then I measured it with the test on the board without the bu. I was going directly from the base to the collector of the q402, that's when I got to the 681k/2kv capacitor c402, which was shorted, so I added another one and it was fixed. obsv: 681k is the same as 681 picofaraides or almost one nanofaraides, you don't need to measure it directly, thanks guys from the forum | This email address is being protected from spambots.

| GRADIENTE | GT2022 | When it turns on, it takes a while for the tuning to come when it heats up, the air picks up the normal channels | The defect was the varicap. | I replaced it and it went back to normal. | This email address is being protected from spambots.
