Green and blue faded


Some of these had bad picture tubes--(model indicated here uses 3 tubes)

Simple test is go to a black and white channel and turn color to zero= is the screen black and white or some other color?

Also go to a unused video input and look at screen=all you should see is black screen with the input number in green= any other color and something may just need to be adjusted.

hello High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

Het Big AOT-

Sounds like the screen drivers for the blue and green projection CRTs sre possibly going south, or it could possibly be the CRTs(picture tubes) themselves going bad, although it would be highly unlikely for two tubes to go south at the same time. My money would be on the control circuits (screen drivers).

The easiest way to troubleshoot this problem would be to obtain a can of circuit cooler from an electronics supply house and determine the area on the motherboard where the screen drivers reside; then turn on the set and let it heat up until the problem occurs, and then carefully spray (one at a time) the components in the screen drivers area. When you hit the faulty component (probably a chip), the problem should clear --- until that part heats up to failure point again.

Determine the part #, obtain a replacement part, replace it and hopefuly the problem will be solved.

The last time I encountered a similar problem in the real world, it turned out to be a cracked circuit board, and all of the intermittently broken circuit lands had to be bridged by resoldering over the cracked area... a tedious and time consuming process.

If the set is still covered under warranty, let Sony fix it... any attempts by you could void the warranty!

Hope this helps and good luck! Keep us posted as to your results...

You have a bad blue picture tube. If you replace it the red and green will be weak and probably go sooner than you think. Everytime I had to replace a tube in a sony projo tv i had to replace all 3 picture tubes at the same time. It's very expensive if you don't have any type of warranty coverage.
