Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
When I try to power on the TV nothing happens and it makes a funny noise? It 's a high pitched noise that goes to a lower pitch. It will make the noise a few times then do nothing. DOes anybody know what this means? Thanks.
I work on these at the shop alot(THERE THE TESTAMONAL FOR THESE SET LOL) ok these sets itc222 chasis from rca have a processor that shuts them down for one of 25 different resons. THe sound you describe indicates to me a few possibilities. the first thing i would check if i had it in the shop would be what is known as the flyback and the horizontal output transistor. if you are a tech. these set can generate pot high voltages so be careful. there is some times i have seen loose ribbion cables but that is rare
