60" Philips Magnavox Projection TV Red Screen

We just got a 60" Philips Magnavox Projection TV that is about 7 years old. The screen is for the most part all orange/red but you can still see the picture. Can anyone tell what is wrong with it? And possibly tell me what it should cost to get this fixed? Thanks.

    I know that the blue bulb is not lit so that is why there is a problem but I wanna know if I can fix this myself. Called a TV repair guy and he wanted to clean the whole thing for $300.00. Too much for me so I need help!!

I bought a crappy old magnavox and rebuilt it. I had both of these issues.
Since your tv is old, the blur problem is probably caused by old coolant in one or more of the CRT lens couplers. Hopefully, the lenses are simply out of alignment, but no one has ever worked on the tv, then this is unlikely.


First, unscrew the back panel of the tv console (should be a bunch of 1/4" hex head screws). There will then be a large white panel at a 45 degree angle held in place by two tabs or maybe even screws. Remove it to see the CRTs. A quick check for the blurry problem is to look directly into the CRTs while the tv is off. DO NOT do it while they are on if you can help it, as it is not good for your eyes.
Shine a white LED flashlight down into each of the CRT's top lenses. Avoid classic incandescent light in this case, since you will be looking for the difference between white and yellow. I you see a white plate inside, good. If the inside looks yellow, and has floating things in it, then the coolant fluid inside is old and bad. You can replace this, but it is a VERY delicate task and MUST be done in certain steps to avoid ruining the electronic boards anywhere within splash zone or drip reach of the lens couplers. The coolant is a special blend available at most tv repair shops, but it's basically clear antifreeze (which you wont likely find in an automotive store).

For the color being off, it is most likely the gain on each CRT being out of whack. First, change all of the user settings (in the on screen menu) for image, color, sharpness, etc to the middle or default.
With the back panel off, somewhere near the bottom of the inside there will be a small black plastic box with wires coming out the sides. This box should have 6 knobs on the front of it (the face facing the rear of the tv); 2 rows of red, green, and blue knobs. These are the screen controls for FOCUS and GAIN. And they should already have some sort of label telling you so.
I placed a mirror in front of my tv so I could see the screen as I adjusted, but you might be able to see it somewhat by hanging a sheet over the front of the screen and looking at it from the inside.
There's a much more in depth method to do this that is described in the service manual (which you are likely to have seen by now; they are usually either stapled to the back of the tv or hanging somewhere inside and easy to see)
But basically, just turn the knobs gently around until the picture looks about right to you. (Remember, if you turn them all up super bright, the CRT will not last very long. Try to keep the knobs near the middle of their turn ability)


If you want to do a full out overhaul of the screen, you'll have to make a lot of adjustments with a bunch of little knobs (variable resistors, really) on the computer board inside. The service manual will tell you what each one corresponds to, but most of them will have a subtle label on the board.

Hello, maybe the red CRT is getting weak. Definitely a job for the pro. The life span of CRT is about 30000 working hours. If you need more info please advice. Arpi

Blurry screen

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to...look white, look dull, look red/orange, etc. You may even see halos around images. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

60" Projection Tv - Approx 6 yrs old

Your CRT fluid needs to be replaced. After many years the crt cooling fluid gets a ton of alage built up in the tubes.  This will cause the screen to get a halo effect or get darker.

You only need to replace the fluid in the blue and green tubes.

60" Philips Magnavox Projection TV Red Screen

You can also check to see if you have bad fluid problems, by looking down in your crt's with a flashlight when you unplug your set and see if you can notice any particles that should not be there. Look at all three and see if there is a difference. It should be clear, if not then you need to change fluid and clean.
It sounds as if one of the picture elements (there are probably 3 for R-red G-green B-blue) has gone bad and it is most likely the green one. Sad to say it will probably cost you more to have it fixed than it would to buy a new TV. Most places will not even look at a TV for less than $85 or so, then they will add parts and labor... if they can even find parts.
