Having problems with your Flat Panel Televisions ?

Picture problems Upon startup, the right 1/3rd of the screen has a trailing rainbow effect. This sometimes clears up quickly but sometimes takes hours. When it does clear up the picture is perfect. Then if I shut it off the whole process starts again. sometimes when the rainbow effect subsides the right side of the screen gets very dark almost black and the picture cannot be seen on that part of the screen. Is this a simple component that can be replaced of is it something more? I love the pict

Answers :

A general answer is:

Most sets like this one use two boards to drive the screen--in this one there is one for left half and another for right side.

Different brands use different names like inverter, etc but it seems issue is on right side?

Unlikely but possible is also a issue in the power supply but usually if there both sides or whole screen is affected..

The fact it clears up after some time means it is a thermal or temperature problem---it could even be a solder connection.

The problem would have to be isolated to one board (not always easy) and the board replaced to see if it cures the issue or not.

Also consider spending the time with Toshiba customer service to see if their data base (they log all reports of problems) has some information that might help you.

The right side of our screen keeps going dark, almost black. Once I tapped the side of the tv and it popped back to normal. Sometimes it goes back to normal by itself. It is black most of the time though. Is this fixable?

Yes usually fixable unless its the panel goning bad. What if you squeze the panel where the black bar is does that effect it. If so the cabinet is probably bowed. Hope this helps. ... Sanyo Standard (CRT) Televisions
