Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
Contrast must stay less then one third to have normal color and colors are very cartoony. cleaned mirror and screen and insides which helped alot but color is horrible and screen burn just sticks out more. is it just projector tubes in need of replacement?
I solved the problem by connecting a VCR to the TV and surfed the tv channels with the vcr remote, some how the new video input cables and the vcr solved this problem for me. I just set the tv on Video Input 1 and use the VCR. It wasn't as hard as I thought the problem was, just poor signal.
