53 inch projection tv...seems like the color red and color blue have shifted giving me a picture with red and blue shadows


For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

I have a 60" projection tv philips magnavox model #9P6040 C104 PTV843. The color looks bad, the picture looks orange and red. What do I need to fix it and how much will it be.


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.

The color seems to be off. No red, and lots of purple. This is a Toshiba 57H81 wide screen big box tv. It was purchased in 2002.


Could be a bad board within the tv but it is sometimes the source input meaning it could be dvd player, cable/satellite box, etc causing the loss of color but it is unlikely. I have one of these tvs and they use red green and blue projectors to reproduce the colors so when the red projector fails then you get purple which is green and blue colors combined without the red. I have found it to be sometimes a bad connection inside the tv and I found insects such as roaches inside others. Using extreme caution when opening the rear cover of any tv due to dangerous and fatal high voltage. You might find that simply cleaning out the inside of tv and reseating all the connectors might resolve your issue otherwise you would have haul this tv to a repair shop where you pay half the price of a new flat screen lcd for just repairing this tv which will probaly have another color go out next month.

TV picture is red.


Normal color picture is composed with 3 colors R-G-B (Red-Green-Blue). Picture turns Red means: Missing Green and Blue colors (many reasons: bad contacts, projector tubes dead, and other...). Try to give some "tabs" to diagnose ... I don't know what is the type of your Projection TV, how long you owned it, to have more idea.

Toshiba TP50G50 Theaterview picture is double with red color only


Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!
