Color problem We have been having an issue with our color on this TV... it seems to be fine, and then just go to green or blue - even a bit faded but there is obviously a problem with the color... can you suggest anything we can try to plug/unplug or do we need a new lamp or wheel?

Light Engine is Bad, If you had said TV was making loud whistling sound then it would be Bad color Wheel

This link has the instructions on how to fix this problem and other similar problems. You have nothing to lose, so I recommend that you try it.

This works with the two other colors, blue and green also. Not all models of Sony Projection TVs have the red, green, and blue pots in the same order as the picture that is listed on this link, so you may want to google search for your model's service manual. The service manual can also help you be able to remove the cover for your particular model of TV. I was able to find the service manual for my model, and sure enough, the order of the pots are reversed on mine, so I would have been adjusting the wrong color. Read all of the comments on this link too, because you can find other helpful tips and may even find someone with the same model of TV as you that gives more specific instructions for your model.

I hope this helps you!
Fare well. :)

P.S. you can also clean the mirrors and dry dust while you have it open.

Some paper tints can cause problems with color images, so make sure that you're using plain white paper, not another color such as beige, yellow, or blue. Even an off-white shade can affect your colors.

In addition, paper type can slightly influence your ink color. Highly absorbent papers can draw in the ink so quickly that the printed image may seem dull or a little washed out. If this is the case, try a coated paper that is specifically intended for color printing. If you're printing those important family vacation photos, use a good-quality glossy paper.

If your colors are way off, you may be running out of one or more ink colors. For example, blue and yellow are mixed to make green, so if your grass seems blue rather than green, you may be running out of yellow. Check your ink cartridges and replace any that are low or exhausted.

Thank you, & post back if you still need assistance.

I just had a service tech out and replaced the color wheel. now i have the same issue with the color...the people all look blue. He told me that now the the digital board is bad. It's the board were all of the connections go. I'm not convinced, as I remember reading something about color settings needing to be adjusted after color wheel replacement.

Sounds like the convergence amp ICs bad. They will cause the type of problem and distortion youre describing.

sounds like two separate problems. color fade ?
green gun/band = bad convergence ic

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Mine just did the same thing.  Except for it was green instead of blue.  The service manual states 8 flashes from the light stands for an overvoltage.  After reading the manual for a bit I realized the bottom row of 3 adjuster screws from behind the speaker grill adjust the output for the red, green, and blue colors.  BEFORE OPENING ANY TV OR MONITOR PLEASE KNOW THAT THE VOLTAGE INSIDE CAN KILL YOU EVEN IF UN-PLUGGED so please be careful and only adjust what is mentioned here.  I un-plugged the tv, removed the grill and the board covering the internals, and carefully turned the 3 adjustment screws all the way down.  I then waited about 10 minutes (don't know if this made a difference).  I turned on the tv, turned the channel to an auxilary input (for a black screen), and slowly raised each of the 3 bottom screws one by one up clockwise until i could see a faint green, blue, or red line (depending on the screw), and then turned each one back a hair until the screen was black again.  Only adjust one at a time, the order for colors are blue, green, then red from the left.  I hope this fixes your problems.  Be careful when working inside a tv,  I suggest not using a screw driver to adjust the screws due to the possibility of it slipping and someone getting hurt.

you can turn the Screen controls down a little bit, but I suspect you will need to replace all 3 crts as most of these crt arc sets require all 3. EXPENSIVE if crts are even still available.
