Re: inverters with C5707 benq hp 1940
I just tipped it with my iron before. Now i placed my last good c5707 & removed the solder on the transformer and used new solder to resolder it!
Now my screen is flashing white, black, white -- no image + powerled flashing green <> orange
And the c5707 is broken (short circuit)...
