What causes the yellowish hue in the centre of the screen

There are several different types of projection sets: some use 3 picture tubes, red,green,blue--if this kind of set is what you have the coolant used in the blue tube is bad-----this type of problem leaves red and green which = yellow.

Most common in Samsung, Philips, Magnavox type sets.

If it is a newer set without picture tubes (a dlp style set) yellow in the middle of the screen would denote a damaged optical light engine.

Let me know brand, model number, date made----all are on back of set.

How do you know if you need to replace the fluid? can you show me some pics of good red green blue color or some bad colors

If the glycol is bad, there is a easy way to tell:

Remove the back cover and with the set on use a small mirror--put it over each of the three Lens--red will never be bad this way.

What you want to see is a green picture on the green tube and a blue picture on the blue tube.

If instead of a picture either the green or blue look like a floodlight with no picture--the glycol is contaminated.

What happens is bacteria grows in the blue or green glycol--never the red--for some reason it does not like the red color.

Usually the blue will be the one first affected---picture will have a yellowish look over most or all of the screen (turn the color all the way down and stand back at least 10 feet and look at it,

Changing Glycol involves some important things---this stuff is like antifreeze bit ten times more toxic.

If you find yellow and want to know what is really involved respond to this posting and I will assist you.

Can't fix the color - really blue or really yellow.

Probably Blue CRT shot. Put tint back to center and turn color level to 0. Should look good black and white pic. If blue CRT shot, will look yellowish; usually more yellow around perimeter.

the tv had intermittant solder connections already but h\they appeared when the tv was moved to hook up the digi-box. The solution could be as simple as resoldering the power convergence amps.

Picture is double lined of greens and reds

You have a convergence output IC failure. You my also need a few small associated parts as well. Expect to pay $350-450 to have this fixed.

Toshiba 65H80 has yellow hue.

Check you HD inputs or source. Sounds like the red stream is missing; maybe a loose cable.

Green Picture

I guess it's missing blue. Even if you see the blue crt working it's not enough and focalised. replace the coolant in it and also check if you have some coolant leak on the crt pcb.

Problem with Samsung PCJ522R 52": White is yellowish

It is possible that you may have had a leak in one or more of your CRT coolant chambers, see: Product: Projection TV Bulletin # PJT01-001 Model: PCJ, PCK and HCJ series Bulletin Date: 6/1/01 SUBJECT: CRT Leakage Background: When repairing set for CRT leakage, check if CRT has Expansion Chamber installed. If not, install Expansion Chamber on all 3 CRTs. Production during November 1999 ~ September 2000 will need Expansion Chamber installed. Rear panel will indicate production date. This can also leave a residue on your printed circuit board that would have to be cleaned off to prevent further corrosion and leakage currents. Hope this helps.
