Is it hooked up with HDMI cable?

If so try unplugging the HDMI cable and re plugging the cable in, sometimes those cables work loose and if they are not tight, it will cause your screen to flicker. Happens to my TV once in awhile.

You need to replace the power board, i have the same issue and am looking for where to find the part

sounds like the power supply capacitors CP150, CP120 and CP114 need replacement. You can get the RCA repair kit by that same name from www.tvrepairworld.com which has the caps and the CD with repair instructions.

i had this problem also - however eventually by using the "scan" method rather than trying individual codes i was successful - of course there is no report of the code found

If this is a RCA Picture Tube Rear Projection, the Deflection Board will cause this problem. I do not know though if it is available.

your lamp has gone bad your going to have to buy a new lamp for it

My tv is about not even 3 years old, the bulb was already replaced once and now the tv will not turn on, we replaced the bulb again, but no change... The blue lights come on and flash but eventually turn off.

Also, try taking the remote batteries out. Maybe the power button is broken on the remote...
