:Hi, :I have a mate who has a Wide screen SD TFT TV, but wont be convinced of any :benefit by getting a digital STB, yep he's still using the old reception and :it looks shabby. :It cant even seem to get wide screen format (not sure if that's the only :reason why though) :Anyway, my old Teac DV-B420 slowly shit itself, frozen screen, wouldn't :respond to remote or front panel commands unless I plugged it out (including :aerial) then it did work until it became so slack wit these re-boots that I :bought a new one. :But After looking in the old unit, it was clear that the eight pin chip had :been getting bloody hot so I wonder if I can fix this thing and give it to :Timmy the slackarse mate, for nothing. :See Pic here. :

:there's no add crap here, I just dont have any other way to put a pic up :yet. :Thanks :Mark : : :
Apart from suggestions by Phil and Franc, some of those electros at the top right of the pic look a little suspicious (bulging top), so I would be ESR testing or just replacing them. While your oscilloscope testing on stand-by seems ok the real test should have been performed while operating at full load.
As far as the darkened pcb caused by the controller IC, I haven't seen that problem before, but I haven't encountered that particular IC device yet. On the more common UC384x series I have never seen it unless the IC is severely overloaded. I would replace it anyway.
