Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
When powered on the screen will go completly green and within a few seconds shut off. Does this three times before going off for about 3 or 4 minutes before you can turn back on to see the same thing. If I turn the green adjust all the way down the tv will stay on but stay green with sound. If I unplug the green adjust wire, not focuse, the tv will stay on but with a lot of green tint and sound. I've replaced the CRT board, and the Tube. Also tried a different Yoke. If I plug the green adjust wire in while the tv is on the tube will charge up and shut down the red and blue. The CRT board I bought was used but was told worked. The Tube I bought was also used and was told worked. Both were bought from "different" people. Tried
If you unplug the Green CRT board (neckboard) do you get the other 2 tubes comming on?

could be three different things.
1. could be the crt itself as a tube with dfective phosphure wil do this
2. could be the vertical ic on the crt board
3. could be the focus pac. located in front of tv with 6 adjustment knobs on it.
