10 year old rear projection TV that has been great...until about three months ago. TV picture started to go black. After turning TV off, and allowing to "rest", picture would come back. It seems to be happening more frequently...and quicker after TV is turned on. I don't have the expertise to replace capacitors, etc.so...if you know the problem can you give me a guess (even a wild one) on what this would cost to fix?

Re: Picture goes black
With a shop doing the repair they will almost always say the deflection PCB will need to be replaced which would be about 350.00 plus labor. I would suggest trying to solder the vertical output IC first as that is usually the cause on the mitsubishi rear projection or solder around the flyback one of the two.

I have the same issue, we've had to change our bulb three times in less than two years. now we have 61" expensive paper weight. Our current bulb is less than 6 months old. The TV is only 2 years old and like i said this is our third bulb.
the blue light blinks 4 times. you get sound. then a few minutes the the picture returns... then it goes out, and the cycle goes on.
This is a common problem with the older models. The opt chip fails. You can get a repair kit at www.magnavoxhelp.com. After a few months of getting smaller and smaller the audio and video will go out but the power light will remain lit.
My unit is 9 years old, almost 10 (in 2 months) and started the same a couple of months ago. The only way to fix it is to have them serviced by a tech and replace the projectors. Its just the age/use of the unit catching up with it.
Many resellers sold them with an offer to sell you an optional maintence service where they would fix/clean/replace the projectors for upto 5 years after purchase. I'm not sure if they even have the parts anymore since these tv's are no longer produced. After market repairs are likely to cost as much as or nearly as much as buying a new flat screen tv.
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
this is caused by a bad convergence module, and there are probably some dried out electrolytic caps in the circuit as well. i have one in the shop right now that came in with the same problem. if you have it serviced, make sure they replace all of the convergence modules (there are usually 2, but sometimes 3 of them), because if one went bad the other(s) is likely to go out soon as well.
