Picture color - it is a blue and green picture- no other color- looks artificial
This happened once before - that the color of the picture was just blue and green - I did everything as per the manual changing the settings of color/contrast/brightness etc. Nothing worked. Finally I saw that at the end of the manual it was indicated that you could turn the TV off from the power socket and leave it off for half an hour. I left it disconnected for about an hour and things started to work. Now once again (2 months later), the picture color is blue/green only - and I disconnected the TV from the power socket and from the cable connection for a whole night - and the picture color is still the same artificial blue/green tones. Did everything as per the manual. No change. Any help/advice is welcome. TV is only 3 years old.
Many thanks everyone.
i also have same or similar problem with my 60" phillips hd projection tv, model # 60pp9200d/37. i umplugged satellite receiver, tv, dvd player from wall for one hour. i have done this before when sound went out on tv, tech support said try that. didn't help. when looking for model number, i saw red, blue and green glows from lamps through vent holes on back of tv. each in its own section of tv. i looked on internet for lamps, my model number didn't come up. but a 60pl # did come up. other tvs in house show proper color. not sure what is wrong, just started doing it today. as stated, lamps appear to be working, but maybe red is very weak. all looked same intensity from what i saw from back of set.

Its probably unrelated to lamp, take the lamp out, try it again and look into the lens, if its still very green the projectors electronics are failing. The projector generates pictures as 3 streams of info Red Green and Blue. It looks like the projectors red and blue electronics are failing, but the green is working.
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.

Hi, how is the cable box hooked up to the TV? Is it HDMI cable or componet (red/green/blue) ? When you say totally green, do you mean the the picture is only green with the other colors missing or every color looks green ?
Hi there, this is what we call in the industry convergence board failure. this board regulate the rgb and keeps everything in order so the picture looks nice and clean. when this board starts to malfunction, what you are witnessing is usually the result. I suggestrepairing this convergence board. this will fix the 3-d effect.
Have you tried disabling SVM (scan velocity modulation)? Often touted as a "feature" of TVs, it's a way of artificially making a picture appear sharp. Totally unnecessary. When SVM (sometimes called VM) is on, it can lead to some color bleeding around edges.
When you take pictures under certain artificial lighting conditions- such as fluorescent, incandescent, or halogen lighting, the colors in your image may take on a yellow or green cast. You can use HotShots to touch-up the colors; see Chapter 7 for instructions.
