My picture is pink. I do not have an adjustment to green. My green tube is fine because I have green during Magic Focus. I have updated to the new addresses in E2PROM. I also have tried different inputs and all are the same. I think this is going to be a board level repair. Can anyone help me locate and repair this? Thanks for your help in advance.

Did you do anything to the TV before this started to happen? Did you adjust any of the focus pots or the screen pots? How did this developed?

Need more info...

Thanks for the quick reply! I have never been inside to do anything but dust and it was fine after that. It just happened and not sure why. I did the 117 pt adjustment recently after a move along with the address updates. I do have green during the focus adjustments though. That is why I thought it was a board issue and not a tube.

Hello? Are you there? Do you know anyone else that might be able to assist me? Nothing internal has been adjusted and the tube is fine. If someone has a schematic with component layout I could figure out what i need. Thanks in advance!

Are you using component connections? Check that the plugs are seated fully, and in the proper jacks.

It does this with HDMI or component. Even direct input of the cable jack has no green. Thanks for the reply!

Then I'm afraid it may be your green gun. Call a qualified repairer to take a look at it.

As I mentioned earlier in this thread, I have green displayed during the Magic Focus. The gun is good so can you tell me which board processes the colors for the input signals?

I forgot about your Magic focus post. I'm afraid I can't be of any more help. Perhaps someone else will chime in.

Is there anyone here that knows rear projection tvs? I am trying to find out which board controls green color. I would greatly appreciate any help.

Just came across your post. I have had the same problem as you but a repair person showed me how to fix it myself, even if only a temp solution. If you take the bottom front panel off and gain access to a row of black knobs on the upper left hand side, you will be able to find the one that increases whatever color you are missing from your pic. Did the research a couple of years ago but forgot what they are called. But hopefully this gets you headed in the right direction.

If you are talking about the screenpot adjustment controls...you better tread extremely lightly. Or you will be in for a very long tortue test before you figure it all out. The green screen pot is your reference control. It shouldn't need to be turned very much at all. In fact...I suggest you mark your current start points with a white pen before turning any of them. Or for sure you will get lost without the right instruments to measure the changes. Your grayscale will get trashed. And then you are in for a lot of calibration and tweaking. If you must try this. only increase or decrease gain in very tiny increments. The changes will be noticeable. And ruinous...if you get it wrong. I would suggest you do a telephone consult with Mr. Bob over on the Don't Dump Your RPCRT thread at a minimum. Just my opinion on this.
