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

Re: no pic no sound just ticking
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.

Hello matter0464 and a warm welcome to Fixya. The issue you are asking about is actually rather common with the RCA P56812BL after it gets a few years on it. The problem is most likely the high voltage circuit located on the main board. I would start there before looking elsewhere. Also inspect the 195 AP fuse on the main board as well because it is known to blow out periodically. Well I hope this was helpful and good luck to you. Thanks for using FixYa.
This problems it is the tv convergence board it is dead.The tv convergence board is not distrubuting voltages around the tv anymore.Tries websites like Tvrepairworld.com,Tvrepairkits.com to buy a tv convergence kit belong to ur tv model and repair it ur self.The tv convergence kit also came with a tutoring DVD disc.
The first thing to try is to unplug the unit for 30 minutes and plug it back in and try it. If the unit had a temporary glitch in the software it should reboot and clear the problem and work. If this does not solve your problem I have a tip at
Sounds like the high voltage block,part number 205064,this part is behind the speaker grill,there is a access panel to remove,part is between the left and middle tube,has red wires from the tubes and black ground wires on the left side,hope this helps.
Is this cable connected up to your TV set thruogh the tuner, the RF input, or the video and audio outputs, scart connector? You may want to make sure the cable box does not have a mute or a volume control turned down, and make sure the TV's audiop setting is not on SAP. Good Luck
