did you elimenate the surround from the tv by just using the tv alone some unit could be causing a feed back?

When the SAT button blinks repeatedly, or the buttons do a dance (Sat & DVD, TV & AUX, repeat) it means you need new batteries. Replace all four AAA batteries, ensure they are all four aligned the same way, and then hit SAT. Your remote should return to its normal function. If you leave the batteries out for too long, the remote will forget how to operate the TV and receiver, so be sure to have all four new batteries ready before you remove the old ones.

Sometimes it appear the TV is working again with no problem but it is only a matter of time for the board to get completely damaged.

Sounds like you dlp lamp is going out. That's a pretty old TV and if you are still running on the stock lamp this is exactly the type of thing that will happen. The lamp model for this particular tv is the ty-la1001. You can find that over here:
