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?
