My Phillips Magnavox 64 inch tv has a green tint to it. what can i do about it and how much will it cost and where can i have it done at?

Your fluid, known as Ethylene Glycol needs replaced in the picture tubes. Normally just the green and blue need done. This is what keeps the face of the tubes cool and after time just like your anti freeze in your car it breaks down and needs replaced. It turns what we call "beer brown". At Philips, we were charging $279.00 to do this. Today, places are charging anywhere from 200-300.

I have a phillips 50pp920217 tv and the problem is that one lens or lamp its burned. AT the bottom the pictures has a wave and shadow of color red.

Sounds like some of the coolant has been lost. Refill with the same glycol based coolant as original.

Convergence bowed


the coming out is glycol oil (coolant). If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages.

Looks like a picture tube problem.
Try to reduce the contrast, maybe it will be better.

Look into the three tubes while the TV is running, and observe the
picture quality of the three. If the red and green are crisper and clearer, and the blue's all hazy from bacteria growing in the coolant, then the fluid needs to be replaced. The CRTs of the colors that seem hazy need to be removed from the light box to be
serviced. The coolant needs to be drained, the CRT assemblies
disassembled and totally scrubbed clean and refilled, then reinstalled and converged. If the coolant is
clear, it can be a weak CRT.

Also the convergence STK ships might need to be replaced, and the soldering checked.

Good luck

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.

My 60inc phillips magnovox has poor color, what do i have to do?

we just bought a 55 inch phillips magnavox and told it was working fine when we got it home and turned it on it was a red screen and was really foggy. we looked up some tv repair places and ONLY 1 told us it was the picture tube and to look down them with a flashlight for bacteria! sure enough the green and blue had it. so we found one place that would sell us the coolant fluid that you have to change the others could get it in or wanted us to bring the tv to them. we did it our selves the stuff was $17.00 a bottle or if we took it in it would be about $375.00. we have a great picture now and it wasn't as hard as all the other repair places said.

you need to change the coolant in the CRTs. Thats a common problem with the blue and green CRT in phillips magnavox rear projectionsIt makes the color and clarity as good as new after the coolant has been changed. If you need more info let me know, as there is a kit that has the coolant for all 3 tubes and CD with the step by step instructions with pictures available.

Color & sharpness problem

Sounds like you need Coolant fluid change, this is the fluid under the Lenses. If you have not done this before I suggest that you get some one who is qualified. Because if the coolant leaks and get to the circuit board, there goes your tv. You need new fluid in the 3 CRT's. If you look down with the back off and looking in the lense, you would see contamination in the fluid, this needs to be taken out and cleaned and replaced with new fluid. The fluid can come from places like MCM electronics corp.
