Question about Televison & Video

1 Answer

When I first turn on my Technika tv I get sound but no picture. After hitting the top of the tv it comes on. After a further few minutes the picture freezes and eventually fades away. Further hitting of the tv continues and eventually comes on. After approx ten minutes the picture and sound work fine and continue to work normally. Until the tv is turned off ! ! We then go through the whole process again when turned on again.

The dreaded loose connection syndrome, this could be easy or hard to trace, only solusion is checking circuit boards for bad connections , it may be also capacitors in power supply neading replaced, not a novice repair

    This is highly unlikely, it is more likely to be an inverter board fault of a panel issue. If it was a power issue you would also loose your sound as well as picture

You have a shorted panel that needs to be replaced. This is not cost effective to fix.

Sharp Aquos LC-32D4OU


Comment by Guest, posted on Oct 25, 2008My Aquos has the same problem. I'm not sure how I discovered this, but when I lean the TV forward and hit the power button it will turn on every time. If the screen blacks out and I don't lean it forward when I hit the power button, the screen will just remain blank. It is very weird, but at least repeatable.

- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.

Won't turn on


those tvs will try 3 times before completely shutting down. you can try and take the back off and check CP150 it is a large capactior located near the middle of the board on the left hand side(looking from back) if it looks and feels like the top is vented or puffed out then that could be the problem. if not i suggest having a qualified service tech take a look because there are too many things that could be the root cause.

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
