This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally

I have a rca profection tv. When you turn it on it turns back off by itself


Thats way I solved my problem.

Mitsubishi (and other makes) has had problems with the front panel push buttons partially shorting. This can cause a variety of odd and erratic operating problems, and a completely dead set has been documented as one of them.
The reason the remote doesn't work is because the partially shorted front pushbuttons are telling the TV's micro computer that there is a command being issued by the front panel, and that makes the TV ignore the remote control.
The fix is to replace all of the front panel push buttons. One quick and dirty way to get around this is to simply unplug the wiring harness to the front panel push buttons, hence disabling them, and just using the remote control.
Just pull off the speaker grill from the front. You will see a small access panel on the front with wires coming from the front buttons running inside. Those are the wires you'll want to disconnect.
Take that panel off, and follow those wires. You'll have to undo a couple of plastic cable clamps, but halfway down the wires you'll find two connectors. They have lock tabs that you have to push to separate them, but they should pull apart without too much trouble. One connector is actually the front panel input jacks, the other is the buttons, but you can unplug both of them.
Then cross your fingers and try the remote.
Let me know how that goes!

I have a Mitsubishi 73"


i would suspect your control buttons on your front panel on the set have become shorted. specifically the volume buttom down. This is freezing you control functions. like someone is holding the volume down button all the time. or intermitantly. this cuircit board is on front of the set. I have seen this problem a few times at the shop. The common repair is to replace that button assembly cuircit board. I believe the last time it cost the customer around 85 dollars, but like all things depends on the part and the technician that puts it in.

Tv comes on and then turns off automatically.


This sounds like the front panel assembly(FPA) switches are acting up. What happens with this model is the FPA switches start to conduct just as if someone was pressing the buttons. This in effect locks up the system control or causes it to do erratic things.
The way to determine if the FPA is bad is to remove it by unplugging from set. This requires front panel disasembly. Note:The remote will still work with the FPA removed so the set can be tested.
Let me know if you need more help or info.

Need code to program a universal remote!


general process for a universal remote control:

  1. push and hold setup 3 seconds
  2. select the device to control (TV DVD etc)
At this moment TV has to be ON (turn tv on by front panel)
3. continue with remote control pushing power button again and again and again SLOWLY
4. when the tv turns off then press enter to save your code.

RCA P52939 turns on and off by itself


the front buttons are common for going flaky - if you remove the front grill you should be able to unplug them and use the remote only
if you use the buttons let me know and i will look up the board or switch part # all switchs will need to be replaced
thanks

Tv turns on manually, but auto flips through channels and you can't use remote


Found this in another forum (www.hometheaterspot.com) and it fixed my remote problem:

"...it's possible that one of the front panel buttons is "stuck" or shorted, and this could cause the TV to ignore commands from the front panel or remote. But this should also cause the Power command to be ignored, too. You might try pulling off the front panel and disconnecting the front panel buttons and then see if the remote works."
