I have an old Sammy TV which after about 5 mins freezes in 4 horizontal bars starting at the bottom. It's usually sorted with a firm whack at the top of the screen but soon returns.
I have replaced the psu as the capacitors were bulging. It seemed to be ok for a day then back to the same as before.
Anyone seen this before? Is it a dead panel?
Its a UK model BTW.
