I have a rear projection Mitsubishi VS-70803 and fixed it with the help of eagle338 it was working fine for a year and a half. So new issue is I was watching TV and all the sudden i hear a faint spark


The set MAY have the self check feature.

If the set is plugged in and you turn it on and a few seconds later the power light goes off:

On front of set press and hold both the menu and input (device on some) buttons at same time for at least 5 seconds and release both.

Power light should then blink a two digit error code like 2 blinks, 2 blinks a pause and repeat the error for a total of 5 times.

If you get an error code let me know what it is.

My screen went blank but the sound works fine. We were watching TV when the screen went out. The sound stayed on. We still get sound but no picture. Is this worth fixing? If so what is the best way to go...


all in one day my screen started by showing a u look at top and bottom. all three colors kind of separated from each other and therefore made shadows on all the writing and double and triple vision on people and images. then it drawed in from sides and showed some black. then it popped in the back and no picture. the sound then came back on with no picture. so i shut it off and unplugged it. what do i have to get to fix this? thank you, Robert Hopkins

Tv went pop


All you can do is get it repaired or replace. Take the receipt (if you still have it) to the retailer you bought it from and ask about it. Alternative, phone Samsung (number is probably in the instruction manual that came with the TV, or look on their website) and ask if they can do anything about it.

RCA 32 in TV no picture no sound just a beeping noise TV power is on


The beeping sound is most likely the high voltage generator needing replacement. This is a fairly easy job if you have some tech support to discharge the picture tube. You can go to the following link and leave them an email with your model number and your symptom and they will email you back with the part you need and they provide free tech support with instant messageing so you can do the repair yourself. the HV generator takes about a half hr to replace and takes only the basic soldering ability. heres the link.

No Picture No Sound


were the colors looking 3D before the set shut down? If so chances are its the convergence amp ICs and thats what has shut your set down. Let me know if you need anymore info.
