The TV is about 6 years old, in perfect condition, I'd like to keep it but only if it's going to cost a reasonable amount to sort out. Last year this same thing happend and I opened the back up to have a look around to see if anything obvious was wrong and with a many power on/offs it started up, much to my surprise, so the back was re-attached ...

If the problem is a low or unreliable signal where the TV is located then the "best" (my opinion) solution is a wireless bridge (extends a wireless network to an ethernet portion).
