Re: no power

Something VERY common in this unit that can cause multiple problems, depending on the pins involved, are bad solder connections at PF01 on the micon module and socket PJ109 on the scaler module. Symptoms include; dead set, no picture, picture all one color, intermittent picture or shutdown.
If you do it have a good light and a quality magnification of some type. If you have a shop do it take it to them and ask for an estimate first.
Good Luck!

My Toshiba 42hp83 has a rectangular area of the screen that changes colors randomly from the left-center of the screen down to the bottom. After about 20 minutes of the TV being on, the problem usually...

We had a similiar issue with our SAMSUNG Plasma TV. It had a 2'or 3" vertical bar of random colors on the right side of the screen. It would also go away but then come back. Fortunately for us the TV was still under its original 1yr manufacturers warranty. We called the customer support and they scheduled a service call. The TV repair man took our TV to the shop and replaced the defective components. It took about 3 weeks for the repair.

Direct TV says that they will offer 1080p quality. Need update


1080I and 1080P is more than a software difference. It is a hardware difference in the TV's capability to display a progressive picture at that resolution, so no software update will be able to help you. The processors are only capable of 1080 Interlace, and the TV is only capable of 720 Progressive or 1080 Interlace at it's maximum performance.

Hope this helps you...

Toshiba 42hp83 plasma power supply problem?

I had the same problem. It turned out that one of the cooling fans get dusty and does not work. I opened the back of the Toshiba plasma TV and cleaned the failed fan, and it worked like a champ.
