60" HDTV Projection

the problem on you tv is the convergence ic , this part need to be replace part # stk392-120

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!!

This is a very common failure on Projection TV sets.
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
You can see some example photos and find a solution here...

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.

Repair solder joints on convergance IC's,but your best bet is just to go ahead and have them replaced.I highly advise that a TV tech preforms the work.

you need the phillips DPTV305 - DPTV345 convergence repair kit which is available at the following link which includes step by step instructions on how to do the repair yourself. Heres the link.

call andrews electronics.

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. 

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)

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.
