Thats the classic sign of a failed deflection board. You can get the ITC222A deflection board which comes with warranty and installation instructions from www.tvrepairworld.com its listed as the ITC222A remanufactured deflection board under the RCA CRT Projection Circuit Board catagory

Most likely problem is the Flyback has shorted or CL031 has burned a hole through the deflection board both on the deflection board. Replaceing the deflection board is the best way to repair the issue. You can get replacement deflection boards for your model at www.tvrepairworld.com

I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.
