Picture problems I have a 48 in rca rear projection tv. it is 3 yrs old. Lately the picture gets bigger then the screen, then it goes back to normal and then it shrinks small and there are grey edges along the sides then it all goes back to normal and it keeps doing this while watching. It gets worse on the really high channels such as 500 plus and the pay per view stations. I called dish network but they said it was a tv problem. I went into the tv remote menu and checked the tv format. But still it doesnt work properly ,, what can I do?

Bad bulb, replace.

one of the convergence ICs is probably defective, you will need a soldering iron to replace this . there are 2 of them,they start with a part no STK392-XXX

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

tv worked great, turned it off one day and back on the next and the on light would not come on nor would the tv work, rear projection 52 inch rca

Try resoldering the vertical output IC this is acommon problem with this model

my tv is 12 yrs old it started with the color starting to fade and then it started cracklin real bad and now theres no pic but there is sound

1) Reset will not help

2) Older RCA projection tv's usually produce a good pix,
so you could fix it....

3) light box chassis pulls out to go to shop for repair...

4) For more info = provide service # and chassis # off back..

Please rate this solution...............

I had this problem around the time my TV was 3 years old. I ended up having to get it repaired at a TV repair place, it cost me $375.

your location area may be theres a big machines interfering your AC line. as you've noticed it runs normal intermittently. i suggest to use a AC condenser or a AVR for this might solved your problem. good luck.

This must be a duplicate, and since I'm not sure which one you'll be checking back with: Go into the menu and select picture settings and then advanced picture settings. I'm not sure on that model that you can manually change the aspect ratio from zoom to 16:9 or 4:3 ect... But select Auto Format and the TV will pre-select the correct format for viewing..... Any questions just let me know. Bill
