soundwave ctv1405t power suppy burnup
 

I am hoping someone can be of assistance in identifying two transistors
which have died as a result of s/c in above. They are marked on board
as Q104 and Q105
Idealy a schematic of power supply would be appreciated.
Many Thanks

So you mean that the markings on the components have burnt to
unreadable?
In such case, sometimes it's possible to get them just readable by
_gently_ scraping it and using a powerful light to see it. But not
nearly always :-(

post the chassis ref.
i have never heard of this brand before. chances are the guts are made
by orion, beko or vestel....

The only number I can find is printed on the main-board.
PB-MAIN-1405-V5 TW.
Could this be the chassis number

possibly, but not familiar to me in this case.
if you have a digital camera you could try posting some pics on
imageshack.us. see if anyone here recognises the board.

Thanks B.
Now found out Q104=S8550 Q105=2SC368
Which just leaves me one problem; where to get an S8550. Can't find a
retailer stocking this transistor or even supplying an equivalent..
