Question about Toshiba 42H83 42" Rear Projection HDTV-Ready Television

1 Answer

Color change Extreme color change --all greens and blues--no reds at all and all colors are affected--like white appears a blue/lavender color. I've tried to adjust the color through all the menu options with NO effect. I wonder if this thing is shot? It is 3-4 years old. Thanks

Re: Color change

I had my stk's replaced, was able to take out the board and brought it to a tv repair shop, the fellow replaced the circuits and re soldered the circuits and heat sinks. Circuit Barn- Auburn, Mass. Jeff Murray did a great job. Reinstalled, and 56 point convergence, tv looks as good as new. I was disappointed too, because the set was purchased in december of 2002.

Samsung HLR5067 has no green color in picture

I know this may seem dumb but if you are using component video (the red green blue with the white and red audio cables) it could very well be that the green cable (carries the green signal) is the problem. try changing the configuration (ex: use blue to carry the green signal and vice versa) if the green starts to work and the blue stops then its just your cable.

My screen has little dots appearing sometimes red sometimes blues behind the picture i just replaced the lamp bulb as i thought it would cure the problem

the projection tube needs to be adjust for color alignment, each tube (red, green, blue) must be aligned so you there would be no color smear appear on screen. if it is aligned try to set up the color balance, hue etc.

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.

Projection is messing up. Too much red and blue color.

A CRT projector requires Convergence and Color balance adjustments from time to time. These settings can drift. What you are seeing is a lack of Green color intensity. Do you see some pink in the 'whites'?
The Green CRT surface also burns off faster than the Red and Blue leaving behind the same appearance. As long as your Green CRT is not too burned by gaming or watching Golf and football, a local tv tech will be able to dial it in for you.

White colors schemes seem off white color or brownish color and blue has green tint or baby blue color. .

Check the coolant in all three crt's as chances are it is contaminated (should be crystal clear). If brown (beer color), replace coolant in all three crt's and perform convergence adjust. Picture should be like new!!!

Good Luck!!!

Red , Green And Blue.

Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.

No. your problem is related to the coolant in the green CRT has congealed with bacteria and needs to be changed. Thats what causes the halos and general poor picture and color quality. The blue should be changed also. The red for some reason doesnt seem to be affected by the bacteria problem. This is a common problem that happens with all projection TVs phillips and magnavox TVs
