I have a 56" rca p56812bl which was given to me. When i plug it in all i get is a ticking noise from the back and it won't power up. when i disconnect the power supply the ticking doesn't go straight off it slows for a few beats then stops. Any ideas on a fix. Thanks
This set normally has problems in the horizontal and high voltage circuit. The horizontal output will short out and I often change the high voltage transformer. The high voltage splitter is another one of the usual suspects. Since it's ticking at plug in, then, I would look at the secondary of the high voltage transformer or the regulator circuit. Checking the the horizontal output first for a short and if ok, checking the B+ voltage on the collector would be my next step. That should give a good thought as which direction to go. Hope this helps.
