Television and Home Theater

I have a Sony Bravia KLV-40U100M LCD Television.  After about a year, I started having a problem where the TV will just randomly shut down while I was watching a program, and then it will start back up a little bit later around 30 seconds later.  It is and always has been on a surge protector.  There doesn't seem to be a pattern where it happens aftre a certain amount of time.  Sometimes it is after 5 minutes sometime after a few hours, sometimes it doesn't happen at all.  It is getting frustrating.  Does any one have any idea why this might be happening??

Hi all new here. Last night I decided to take the cover off of my 10 year old Mag t.v., hasn't been used in 2 years or so because picture got so dim and we just replaced it with a new one. So I take the cover off and astonished at how dirty-cobwebs everywhere boards covered in a 1/4 of dust/crap.

I'm hoping someone can help. I have an LG CRT TV, and needed a VCR to play some old VHS tapes. For some reason, no matter how the VCR is connected (via antennae cord, AV inputs ...), the video signal is wonky (hitting pause shows an image, otherwise it's a sort of static). All the connections have been thoroughly checked so it's probably not something as simple as connecting to the video in on the VCR. I live in Australia, so the TV should be receving PAL. I tried pre-recorded and home recorded tapes, and all have the same effect.
