Re: RCA 46" Projection TV 10 years old

No shure to what to say,
- I would suspect bad CRT, does it have drive line when it does this, if yes on one tube only then tap it to see if the problem goes in or out
- could be cold solder joint this will also show if you tap the board
- would check the board on the nech of the picture tub to see if there is bad solder.
- I also seen bad screen control, this is the black block in the front of the unit that looks like 3" x 3" about 1" deep and has 6 contron to turn on it and has lot's of wires attached to it at the back.
- Could be high voltage block, very commond proble but don't think it would give colour problem.

I hope this help

Toshiba colours gone wrong

Yes it is repairable. One of two things is wrong. The color wheel is going bad or the DMD board is going bad. These are the most common repairs needed for a Toshiba. I hope this will help.

Blue, green, and red colors all off

I would suggest having a repair person come out to your place to fix this problem. I believe the convergence IC are going or have gone bad. I would estimate a $300 - $400 dollar repair bill.
