SOURCE: replacement of the green lamp(picture tube) in a

You can probably purchase a smilar set on Craig's list for $300.00, at least that's what they go for in the Austin Texas area.
A new tube may be too expensive and difficult to replace.

Picture stays on for a few minutes then turns off.. what could be the problem? light bulb? can i do it myself?


This model TV is a CRT projection and does not have a lamp. It has 3 CRT tubes (Red, Green and Blue). Unfortunately, you may need to have a trained TV technician diagnose this further.

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.

You have a bad blue picture tube. If you replace it the red and green will be weak and probably go sooner than you think. Everytime I had to replace a tube in a sony projo tv i had to replace all 3 picture tubes at the same time. It's very expensive if you don't have any type of warranty coverage.

No picture coming from red lamp


Sounds like you have two differant problems. A red drive or red picture tube is bad and the conbvergence IC's are bad. To test the red drive disconnect the green picture tube socket BUT MAKE SURE THE SET IS UNPLUGGED!!Then remove the red socket and move over to the green tube. Then turn on the set. If you get the same out of the green then you have a drive problem that needs to be trouble shot for a bad componet. If you do get a picture with the red connected to the green then the red tube is shot. If you know how to read a schematic, get one and then you should have no problem troubleshooting the red drive and the convergence problem. If you dont then there is no easy or quick fix as this is a solid state set and there are no user replaceable parts inside this.,. Your going to need, for safetys sake, call in a trained tech to assist you with this repair
