black screen a my benq fp71g, but the green power led light ok.

I found that there was tre defects:

• Fuse 3 amperes, pf801
• defect transistors q816 and q815
• bad solder on capacitors c824

the 3 ampere fuse was blown

q816 and q815 was short circuit, replaced with bd139 (Note: these are constructed mirror image to the original transistors - fit them backwards to the original transistors !)

And finaly bad soldering, proberly the reason why transistors burned of
