SOURCE: toshiba 36zt29b television

Hi, I am an idependant service engineer, who is currently looking at one of these actually a 36 inch 36zt29b. So far, it looks likely the digital board is at fault sending an 'off' signal to the digital power board. The digital board itself is no longer available. I am going to have a look at this board, and try to fault find it. If I have any success I will post again.

SOURCE: Color separates and picture bows on 9 year old RCA big screen.

Hi, This is a convergence problem and you can set it right by changing the STKs. It is a professional job and i have knowledge of people who ruined their tv by spoiling some miniature surface mounted components close by. You may need to look at pico fuses too. I would say seeek professional help if you not comfortable working with electronics. Check out at www.fixurtvs.com,

42 inch toshiba has horizontal white lines when turned on in the morning goes away after 1-2 minutes


Hello,
This issue is usually caused by some "lazy old" capacitors in the Vertical sweep section or cold solder joints. That is a large TV so it would be worth having an experienced 'old school' tv tech fix it. They can easily find the bad component using Freeze Spray that will reproduce the problem by acting as a cold start. Either way this issue will not damage anything else on your tv and may or may not get worse over time.

Big black box across the screen towards the bottom.


In some TV's closed captioning can cause this problem. turn off CC and see if that helps.

Big black box on screen


It has something to do with the closed captioning. He must have hit the closed caption button on your remote. You need to either turn the closed caption off or make another selection under closed captioning like cc1 cc2. Just keep making selections until the box goes away.
