Sansui TV giving problems

[cr@zydude]

I have an 84cm Sansui CRT tv. I've had it for about 5 years now, it work fine until about July. It then start switching off randomly, and sometimes wouldn't turn on.

I suspected the power supply was damaged, and took it in for repairs. They guys at the repair shop said that they changed the power supply, and I took it home. It work for about an hour, and the turned off again.

This cycle off working sometimes continued for weeks. I have now taken to the repair shop and back 3 times. very time the guys at the shop tell me there is no fault, but I take it home and the problem continues.

I have seen teh TV work in their shop, an have no idea what to do now. Is this a problem with Sansuis, has anyone else had this kind of problem?

is your TV perhaps sitting on a large sub/sound system?

It's on a cabinet, above a CD player and dvd player. The speakers are above it though, but the sub is on the ground next to it.

how big sub are we talking here?

it's just weird that it works fine in the shop but not when you bring it home?

Pretty small, the 'box' is about 35cm diagonally, and the 'cut-out-bit' is about 8cm across.
