Question about LG RU-52SZ30 52" Rear Projection Television

60" HDTV Projection

We just moved a Philips 60" hdtv prjection down three flights of stairs and up three flights of stairs. Prior to this the television was not turned on for at least 2 weeks. When we turned it on, we noticed a yellow discoloration on the edges of the television. Any ideas on what this could be and how to fix it? we do not have the remote to make adjustments until it comes in the mail. Thanks!

If it looks like the picture is yellowish all through it, then you will have to have the coolant replaced in all three CRT's. It is not unusual for algae to grow in the resivors.

Philips prjection tv turns with no picture then turns its self off

You need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

Projection T.V.

It is called Ethylene Glycol (PTV Coolant is what you ask for) . I don't believe radio shack has it, you can try, however, all Electronics Parts Suppliers will have it. If your going to do all three tubes then get 3 - 16oz bottles.

Projection Lamp for Philips 60PL9200D/37 TV



More than likely the problem is the CRT fluid and not the tube. Do a few google or fixya searches on CRT fluid and to get an idea of what it looks like when it gets cloudy.

Cracked screen and down screen

If the double images are located at the bottom on one side, you might have cracked the mirror inside the set and it has been displaced making the picture in that area bad (especially if the rest of the picture is OK)

Disassemble Rear Projection TV

well the short answer is : Check the sides of the set see if there is a crack in the middle where you could separate them
Long answer: i would not recommend it even if it does, the screens are sensitive and could get dust inside the screen.
Never taken one apart that far. i suspect most tech don't because of the problems aligning and dust ect.. trying to get it back together.
