T.V. dead RCA projection t.v. working just fine. I moved it across room, plugged it in and now all I get is three beeps then nothing happens. Power cord seems o.k. What else could be wrong and is it something we can fix ourselves?

Sounds like the receptacle is dead

Have you tried another power cable ? If you have the same problem then yes it is probably dead.

You have a capacitor that has gone bad on the HV power supply board on the left side, the number is cp150.It sits behind an aluminum heat sink in the middle towards the front, it will probably be bulged at the top. Along with that since the board will be tilted up I would re- older all the connections on the HV transformer, that's the critter with the red lead coming out of it. Your done!

Hello,
Power supply board have problems,just not dead yet.Replaced the power supply board,will solved this problems.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Check the fuse on the AC filter board. If you trace the power cord into where it plugs in on the small skinny board located on the right side when looking in the rear there is a fuse on that board. If its completely dead I would suspect that fuse.

Ur DM power board have burn capacitors,check for puff up capacitors,and replace it.Tries these websites.Tv Repair World.com Shopjimmy.com Ebay.com or Partstore.com.

More than likely it has bad solder connections on the circuit board. You could try tapping lightly on power supply/deflection boards to see if it makes contact. Usually I find bad solder on those right under where the power cord plugs in, on the bottom of the board. If you have a soldering iron and solder you could save a few hundred dollars in repair costs, but use caution and make sure all power to set is disconnected. Maybe mark each plug as you disconnect them. Hope this helps. Good luck, Russmann.

Beeping in that model usually refers to the flyback needing to be replaced or the Horizontal output transistor. Flyback is most likely the cause as the HOTransistor will usually blow a fuse causeing the set to be dead.

Same exact problem as above three. Now what?
Wish I could hear how others resolved the issue - or did they? It's just over a year old.
