Hi I have very little knowledge of TV electronics but I have worked on other electrical devices, I had a very similar problem with my Thomson 32" TV (I had a whistling noise before it went into standby). and am pleased to say I have cured the problem myself!! If you have a soldering iron and the ability to use it I will describe what I have done. Obtain access to the main printed curcuit board (I left my TV unplugged overnight to enable any residual power to subside). on the main board (on mine upper left 1/4 of board looking from the back) you will see a circular group of solder joints (about 9 or 10 joints) that appears to be the main component that connects the curcuit board to the screen,check these joints to see if they have gone dry (they will appear to have a ring around solder joint)if so you might have found your problem, desolder these joints and remake with a good quality solder joint. I carried out my repair 5 days ago and am pleased to say my set has not gone into standby since. best of luck Stuart
