RCA-occasional picture blackout-sound ok-menu always ok

[cliffale]

I have a 35 inch RCA Model F35665. The sound is always on but sometime
the picture goes black either as soon as I turn it on (picture blac
with sound) or as I'm watching (stays black between 5 and 30 minutes)
The entire time that it's black the menu functions work fine and i
displays the channel title at the bottom (ie ESPN or FOXN) but th
picture has gone. It isn't as though it's black like the TV is off, i
produces light, it's just the the picture is dark. Any idea how t
repair this television? ANY help would be greatly appreciated for thi
novice. Thanks.

Q43??, I think, the part number varies from chassis to chassis also,
doesn't it?
