press power button, press menu button. do you get a menu? if so, might be loose connections or faulty ground lead connections. with power off, reseat (unplug one, plug back in, repeat on all connectors) connectors on all the boards (including speaker cables).
Then carefully, with the unit on, check all the ground cables to ensure they are all screwed in tightly.
If the television has a menu, there could be a problem with the input board itself. Might not be grounded, might be bad altogether. If it looks fried and smells fried, its probably fried.
Check CPC or Farnell for a power supply repair kit, normally they involve a bit of soldering and about 20 components like resistors caps and voltage regulators. they normally cost between 10-30 quid.
this might be a bad or temp sensetive tuner, why don't you try hooking up a dvd player to your video jacks and see if the problem is present while watching a dvd disc. If it doesn't then you may have to replace the small signal board(where the cable or sat feed hooks up to the tv).
IT GAVE OUT A LOUD BANG AND NOW I HAVE NO PICTURE OR... Mosfet Transistor blow out. Transistor K3316 or replace the Power unit supply. This problem was caused by a low power voltage.SONY SONY KE-42TS2U
