No Red Color

Panasonic Projection TV PTL4074S, about 14 years old has blue, yellow and green but no red color. Neither adjusting the color nor using the "automatic" balance helps. The picture is aligned perfectly, color is the only problem. The color problem is the same for VCR & DVD viewing. Other TVs using the same cable work fine.

I don't want to put money into it; it was purchased used 14 years ago. Any suggestions?

CRT Problem

One thing you should look for is if the RED CRT is lit. 14yrs old I would highly suspect the red CRT or connections with it. Take the speaker grill off and you will find a access panel, remove it. You will find the CRT's, first check if the filaments are lit. If not check the board where the filament is not lit, more than likley the RED. Connections like to come loose, solder get's weak, etc. Hope this gives you a start.
