I took the back of the tv off and the blue lamp is not bright like the red and green. Could this be a coolant problem or lamp. I have the PT5492S Akai rear projection TV.

The blue is usually dimmer than the other two lens; what I would suggest is try to look into the lens with the set on; BE CAREFUL AND NOT TOUCH ANYTHING INSIDE THE SET.

If the red and green show a picture but the blue looks like a floodlight you have bad Glycol in the blue tube (common in these sets).

If all have a normal picture remember to wipe the lens clean at the top; do not try to take the lens etc apart.

Before you rate this information let me know what you find.

When looking for a replacement lamp for my RCA D52130 I can't find any reference to it anywhere. Does anyone know what lamp it takes and where I can get one?

This TV does not have a Lamp. It has 3 Tubes, Red, Green and Blue and they, don't go bad quick like the lamp they normally last for years.

Good luck

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
