Got our 28" Bush widescreen TV (model WS6680SIL) from Tesco 2 years ago and recently its developed an odd problem.

When you turn it on the sound id fine but the brightness on the image goes from normal throught a slow fade to black where it stays for a random ammount of time then back to normal.

A sharp smack to the side reverses the direction of the fade. (eg if its getting darker it starts getting lighter .. back towards normal).

I should add that the bridghtness/contract levels in the menu are not actually changing, just the screen goes dark regardless of the brightness setting.

Been quoted around £50 to have a go at fixing it by the local TV store.

Ive had the back off it but i cant see any loose connections.

Anyone have any ideas what action I should take / heard of this problem before?

Sounds like a dry joint on the tube heaters, have a look on the tube base printed circuit board for a dry joint and follow the wires from the circuit board to the main circuit board and check where they are solderd to it, also check for a dry joint around the line stage, this is where the large transformer is.

i've had 2 of these blow on me. 1 lasted 2 years, and the second, 4 years.

i bought them both at the same time as well.

I took it apart agin and checked all the connections, couldnt see any dry connections. got rid of all the dust and dirt i could see and put it back together.

Thought id try it and it works!

Dont recally actualy doing anything but its back going now.

Thanks for your replies.
