Do you have the convergence option in the customer setup menu? IF YOU DO NOT consult the tips and tricks section of this website for the article ' "The fl231 fuse problem" If you do then it will need some more trouble shooting

SOURCE: When I push the power button on my RCA HDTV

Sounds like the bulb went out.
Go to http://www.purelandsupply.com/RCA-Projection-TV-Lamp.html and order a new bulb for under $200.
They are easy to intall; a screwdriver and 10 minutes.

TRY THE BLACK LEVEL SETTING AND CONTRAST SETTING

SOURCE: no picture good sound good lamp can change channel

I have the exact same TV and have had the exact same problem. I talked to a TV repairman who said it has to be my deflection board. I just found this out today so I am looking all over the web for a deflection board. I hope this helps! Tyson
