I'm working on an RCA television 30 some inch . It had the chirping thing going on. It had popped the MOV. I replaced the flyback, HOT and another transistor , the MOV also. When I turn it on I get brief illumination at the corners of the screen and then it goes into shut down. I still have something shorted out I believe. Does any one have experience with this problem and know the trail of parts to be replaced ? Thanks
