TV was put into service (new) in 2003. All red was lost from the picture a few months ago. I am guessing that it is either the picture tube or a component on the CRT Driver Board. I am looking for an informed opinion as to which. It appears that I can buy a CRT Driver Board that the seller states is in working condition. The picture is otherwise clear and sharp, but somewhat green and blue.
I appreciate any help.

Have you checked that the loss of reds occurs for all inputs as well as the integrated tuner?

Yes, the red is gone on all inputs, e. g., VCR and satellite.

All component inputs.

Most likely the transistor handling the red channel in the video amplifier has failed. Do you have a schematic or service manual for the set?

Yes, I have both. It looks like the device that you mention is located on the CRT Driver Board.

Please excuse the delay in responding to your post and thank you for responding.
