You have one of two problems based on your description.

1.) Go to a channel that is in black and white and turn the color on the set all the way off.

Examine the screen and picture from several feet back----if the picture is mostly red and looks somewhat yellow in the main part of the screen you have a GLYCOL problem.

These sets have on each picture tube a sealed unit full of Glycol to cool the face of each tube (set has a red, green, blue picture tube)

If you find the yellow/orange look with the color off you most likely have bad Glycol in the blue picture tube---it never happens to the red--bacteria gets into the glycol and eventually there is no picture coming from (in most cases) the blue tube.

Loss of blue will leave you with Red and Green--mix those two and you usually get a orange/red affect.

There is a way to also confirm this with your eyes--it involves getting the back cover off of the set and holding a small mirror (with the set turned on--you have to be careful not to touch anything)

If you look in each lens you should see a fine picture--one red, one green and one blue--if as I suspect the blue tube is contaminated it will not have a picture and will look like a blue floodlight.

IF THIS IS NOT YOUR PROBLEM--GO into the customer menu and select convergence--what you are looking for is will red and blue adjust or not--are they skewed and will not move.

If this is the case you have a convergence problem--I can tell you what is involved to fix in either case.

I lost my picture I still have sound but no picture.


I have a Philips Magnavox Projection TV.

I had dish satelight install on my TV. It worked well for two days, then the picture started showing in a square box. I ffixed the convergence and it seemed okay. The next day I turned on the tv and it had sound, but no picture. When I press the status button, the picture would come on then go right back out. Now I don't have any sound or picture. Here is the model information:

I have aMagnavox 9P6040 C104.The picture is extremely poor.


The problem is the fluid in the Blue and Green CRT's needs replaced. ( ethylene glycol ) It not something you should attempt if you've never done one. The average price with most shops is around $250.00, and your other concern, there is no auto convergence on that model. It's all done by remote in your menu and in the service mode, but that's not your issue, just get the fluid replaced and your back in business. Have a nice Holiday Weekend.

The cooling fluid in the CRT's need to be replaced. This is a common issue with NAP projection TV's. The old fluid needs to be drained then the CRT faces cleaned then refill with new fluid.
