| 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 | GTV142 | After a concert and changing the vertical output, the TV turned on, but then turned off, using a timer. | The shutdown occurs due to factory default protection when the CI understands that there is a tape in the video cassette compartment. | Solution I placed a tape manually, after dismantling it completely. Once this was done I turned it on again, with a video cassette tape inside. the timer recognized the setting, releasing the tape and disabling the system. That's it, another headache resolved. | demervalignacio |
