Hi there,

I've recently recap a working Chassis, a Toshiba PB9929, unfortunately right after finished, ive detected a short capacitor, that prevent my board to work properly,(no picture and a strange whistle) long story short, after fixed the short, chassis still wasn't working, and i noticed a very hot (thermal camera) area on the board.

The 3 pin transistors named CHY on trace Q807, Q806 are faulted , and they needs to be replaced, they both gettin' really hot.
What can a replace them for?
Thank you
