Now, I can get the part for $10. I just don't want to take the tv
to pieces and screw something else up. Does anyone have a service
manual? I'm handy enough with computers or regular board repairs. Just
need documentation to make me feel better about it. Thanks in advance...

Unplug the tv let sit for a minute while you replace the batteries in the remote and cover the IR remote sensor on the front of the TV. Cover it with a piece of black tape or a piece of aluminum foil.
Plug the tv back in and turn on.
If it no longer turns on and off by itself then you have IR interference from some other remote operated device in the room.
If it does continue to turn on and off with the IR sensor covered then it is the internal wiring/processors and will need servicing.
i know this may sound silly but check the batteries. now if you allready changed them and your still having the same problem check the ir signal on the remote. now all you have to do is take any camera( camera phones work just as good) hold it to the ir sender on the remote press any button on the remote and look through the view finder on the camera. you should now see a light go off on the remote through the camera. if you dont see a light then you have yourself a broken remote. if you do then its possible its the tv ir reciever. and may need to be serviced. but hoping its the remote you can always get a replacment remote for cheep.
The IR detector is in your TV set. It is the device that picks up or captures the IR signal from your remote control and turns it into an electrical signal that the TV via a processor interprets as a function or command to have the TV perform in a certain way as turning on, channel up or down, volume up or down, etc.
I have heard of similar problems, but have not seen it happen first hand.
My first thought is that you should remove the batteries from your
remote and see if the problem goes away, if it does then your remote is
faulty or has sticky buttons, if not try...
Place a piece of tape (not clear) over the tv's IR sensor, this will
block any ir signals that may be coming from another source. If this
corrects the problem then you have something in the room that is
generating a light source that the ir receiver is mistaking as a valid
I find it hard to believe that the tv's circuitry is at fault, but it
can happen. Make sure you have no sources of electromagnetic
interference close to the tv, such as any external speakers, or any
other electronic equipment. Unplug all other electronic devices that
are near the tv and see if the problem goes away.
Hope this helps!
The IR reciever should be in the front of the set where the remote IR window is located.
I can tell you that there is a lot more that can go wrong than just the IR reciever. There may be a buffer amp along the way to the uPC, or there may be a fault with the uPC itself. The fault may also be a cold solder connection, or a missing supply voltage to the the IR reciever or to some of the components involved in the IR signal process.
In opening and working on your set, there are serious safety issues involved. You should be giving the set out to a trained and experienced TV tech for proper and reliable service.
It sounds more like a problem with the TV, than the remotes. It's possible that the IR reciever or microprocessor for it have pooped out. It's something that would have to be serviced by a shop, but due to the age and size it would likely be cheaper to replace the whole TV.
