MY R.C.A. MODEL 20F420T WILL NOT STAY ON. TURN IT ON IT MAY STAY ON 3 SECONDS TURNS IT SELF OFF TRY AGAIN IT MAY STAY ON 2 SECONDS BACK OFF THANK YOU ????


The first couple of seconds of operation, most TVs are doing some self-test and if something has failed making full power on dangerous (for fire) they will shut down. Either a major component in the horizontal section has failed or the main power supply itself is defective.

Picture was fine, then lines diagonally, now light


Projection sets have two very common problems outlined below.

The first common problem is 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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

Green Screen, No Sound, Shuts off after 10 seconds


Almost certainly the green picture tube is shorted. This is a very expensive repair; probably not worth doing.
