Trouble w/ my Phillips 50P8341 50 IN. HELP!!!

I have programmed TWO Philips universal remotes for my Symphonic TV and the remote will work for a few days, then the TV stops responding. It will not accept any code. I have programmed TWO Philips universal remotes for my Symphonic TV and the remote will work for a few days, then the TV stops responding. It will not accept any code.

I have a great 50" 50P8341 television from Philips I've had for about 5 years now. However, for the past 7-9 months, this television has developed the nasty habit of deciding to start 'ignoring' remote control AND front panel inputs for 20 seconds up to 90 seconds! Press volume UP button--- and ... 30 seconds later the volume will increase by 2 notches. But don't you DARE hold it down, or in 1 minute you will be BLASTED OUT OF THE ROOM as the volume goes up through the roof and you are unable to get it to go down again for another minute or two... 
This same situation occurs with all front panel inputs (EVEN the power button!!) as well as all remote control inputs.  

ANY idea on what is going on here would be useful. 

SO far: I've noticed this happens when a) the tv is used for LONG periods of time (kids watching most of the afternoon on Saturday into parents watching Saturday evening... b) When the VCR is unplugged from Side input and Playstation II is plugged in, (in fact, for a few days, we couldn't even GET the side input to WORK)

The only (unreliable) means of helping a little has been to unplug the TV and give it a rest for 2-8 minutes and then try again. though this is not a sure fix-- even after an hour's rest, it may not work correctly after being unplugged, so we are at a loss... yet sometimes after unplugging and immmediately plugging back in--it works. 

Go figure...
