The color is very red, and the color flickers and changes. Also, the set starts flashing green and then shuts off. I called a few repair places and they said I would need to replace all 3 tubes at great cost, is that the case? Thanks.
My tv screen turns red as it heats up and the repairshop told me it would cost $600.00 for a new red projection gun how ever I don't think thats the case because it is a heat related issue. I think an ic or transistor is going bad and goes into saturation when it gots warm. I will be spraing some components with freeze spray and if my hunch is correct the color will temporarly correct its self when I spray the right component.

I had a TV do that about a year ago, the repair man said it was the color wheel inside the tv. I changed the bulb to see if he was BS'ng me and eventually got the manufacturer to send a color wheel and I change it myself, was very easy...TV works fine ever since. Hope this helps
You have 2 problems. Problem 1 either you main board or light engine is bad and needs to be replaced. Problem 2 is exactly what your TV says. Fan#1 isn't functioning properly so a heat sencor is being actiated to shut down your set. Make sure all the fans are free of debree and spinning. If one is not spinning, make sure it has voltage going to it. This will let you know if you have a bad fan, or a bad board.
IF YOU HAVE A RA 6 CHASSI THE TUBES RUN HOT ANOID CATHOD SHORT IF YOU TAP ON THE NECK OF THE TUBES AND GOES TO SOLID COLOR THEN SHUTS OFF YOU HAVE TO REPLACE THAT TUBE ALL 3 TUBES WILL HAVE THIS PROBLEM
I would suggest either the Focus block or the RED CRT drive board either one of those items could cause the symptom. A defective CRT could also, but a shorted CRT doesnt usually go back to being normal
When ever a tube starts to short or is shorted set always will have over bearing drive lines then shut down like RED if it was bad, set would come on long enough for red lines across set then shut down this is the same with all 3 tubes.Also if you think it might be green tube disconnected green CRT board on neck of green tube if set comes on and plays then it is green tube do all 3 tube this way one at a time this will tell you if you have other problems.
You need to adjust the votages going to the crt's. As the flyback transformer starts to go out the voltages to the crts can go up and down causing the tv to shut off. It also causes red, green, or blue arced lines to show up on the screen. It can also cause some color fading in and out or flickering. Adjusting the voltages can fix the problem temporarily but in the long run it's a good idea to replace the flyback. Make sure you read up on how to do this safely.
