SOURCE: I have no picture, no sound, and no backlight on

I just experienced the same exact problem, and like most, I went googling for advice. It turns out that my local audio/video store that handles RCA has almost a 100% success rate on knowing what causes this.

This is a power supply problem. When you have all three occurrences (no screen, no sound and no backlight) it makes sense. We usually are too ill-informed (and usually angry at the time) to calm down and think things out on the simplest of levels.

Invariably, there is a known anomaly for inferior capacitors in a lot of American-sold products. This usually gets cast off as "It will cost more than the TV is worth". Not true, though many of us go buy a new TV, anyway.

I'm glad I took the time to find out my TV was repairable for under 50 dollars by having the bulging capacitor in the power supply replaced.

Sometimes advice is only as good as you pay for it, I suppose, but sometime you have to slow down and make a decision that has a real voice or a real face on the other instead of clicking the spammy writers in here.

Lines on display, numerous horizontal, 3 vertical


This problem is caused by a defective LCD display. It is a common problem too. The only way to repair it is to replace the LCD display.

My RCA console tv has white horizontal lines accross screen, picture is very light and sound is ok, very frustrating. I know its an old tv, but appreciate any response. Thanks


Cold solder joints on the flyback transformer circuit board - probably because RCA used feed-thru steel rivets on their boards. Re-solder the connections using a good solder flux for clean solder joints and this will fix prob. The joints with the dull, pitted finish are the problem joints.
