The TV had a broken flay back and burnt horizontal bu, when I changed them the TV didn't show an image, just sound, everything was dark, I looked at everything in the video area and nothing | It was then that I removed the vertical output as it was heating up quickly, and it was the cause of the problem, from the 1st pin to the 2nd pin of the vertical output it was shorted, then another problem came, it was the la7840, so I only had the la 7845, I put it in her and was file | ||

Works but image shaped like a guitar waist | Dear colleagues, I found a defective mos-fet q302 2sk 2961 that was replaced by the 2sk 2545 obs. Be careful with the pinouts as they are in different positions, i.e. just reverse them. I found the 12 volt zd 301 also open when replacing these components and the TV started working normally again. Thanks for the tips and attention and good luck. | Rivaldo | |
