The problem on your tv is the leaky electroltytic capacitor on the regulator section.
Replaced the capacitor on that area and your unit will be back to normal again.
If you don't have an experience in electronics find a qualified technician to do the job for you.
Have a nice day!
Thanks for using fixya.
The first couple of seconds of operation, most TVs are doing some self-test and if something has failed making full power on dangerous (for fire) they will shut down.
Either a major component in the horizontal section has failed or the main power supply itself is defective.
I called RCA about this and first was told that it was my cable company till I told the rep that it does this even when I unhook the cable. I was then told that I could take it in to get it fixed and that even it it was a bad part on their end that I could end up paying for it as if might be the pictue tube or the screen. Guess this will be the last RCA that I ever buy again.
