Put a ventilator pointing at the (open?) backside and see if the problem re-appears.
change all the caps in the power supply secondary. your problem is that Akai ceased to exist years ao, that is now just a name badge stuck on the set. it could be made by anyone....

I checked all caps by ESR they all looks good.No leakage and value matched with cap's sign.Do you think I still need replace all of them?
FOUND THE PROBLEM.The problem was not in PS board but in Logic Board.Just removed each IC from the crib (there is 2 ICs in crib)clean the contacts by contact cleaner put it back and BINGO.Tv starts working like new.Thanks anywas for your suggestions.
