I`m working on a 9`` Orion tv dvd combo 2003 model , same set as the
Toshibas for those familiar with these .
It uses a samsung chassis with a small size package HOT .
Ths set had HOT shorted and the board under the HOT was browned from
heat .
I replaced the HOT with a good original part from a smashed tv set .
This set now works just fine but after around an hour the HOT tiny heat
sink gets to hot to keep a finger on .

I have ESR tested capacitors in the osc circuit and swapped out the osc
coil but still gets hot . I am suspecting the flyback ??
Comments ?

Either the heat sink is way undersized or the retrace tuning cap may be
leaky. Sounds like more HS surface area is a good idea either way.
