Re: Benq Inverter board C5707 Transistors

Hello guys, my BenQ stopped working (lights won't start) the other day after doing a bit of on and off lasting a few seconds, then just dark. I stripped the board and found a pair of the C5707 conducting C-E, thus I replaced them with a pair of TIP3055 together with the 3A picofuse which wasn't working any more as well.

Turned on the monitor and seemed it was working, displaying BenQ's screen and then the motherboard boot after turning on the computer. Only a few seconds and it turned off, then on again and so on till I turned...
