Re: Benq broken chip
1) Post a clear focused picture using the manage attachment function of the entire board. See my sig file below for instructions.Originally posted by quackeruk View Post
2) Circle which is Q601.
3) BTW, this question is better suited in the "Troubleshooting Computer Displays" sub forum.Last edited by retiredcaps; 05-31-2011, 10:49 PM.--- begin sig file ---

Re: Benq broken chip
I am not too good with uploading files. I hope these are ok, I have no photo editor, so have placed a yellow hairband on one of the photos to indicate the position of Q601.

Re: Benq broken chip
I'm more concerned about the darkening around your inverter transformersCap Datasheet Depot: http://www.paullinebarger.net/DS/

Re: Benq broken chip
With regards to the dark area, i have replaced the two inverters, the two driver devices plus all the caps, so i hope the new q601, a three leg device with heat sink.

Re: Benq broken chip
Q601 should be a N-channel MOSFET (that's what it normally is on most monitors). Not sure of numbers and specs since I don't have this monitor.Comment

Re: Benq broken chip
Like I said, the ship is most likely a 1203p60 8 pin dip 'PWM Current-Mode
Controller for Universal Off-Line Supplies Featuring Standby and Short Circuit
Protection' as it was on my board, see my picture.Comment

Re: Benq broken chip
I think there is some confusion here. For Q601, the "Q" designator is for a transistor. In this case, it's the switching mosfet transistor mounted on the heatsink. However, the OP has circled the 8-pin PWM chip in his photo, which should be labeled IC601. The OP needs to identify which component they're really asking about.Comment

Re: Benq broken chip
Ahh now I see what the fuzz was all about - I just saw his picture with the yellow hairband and did not see the 'Q601' part.
If he however is thinking of the PWM chip it most likely is a 1203p60.Comment

Re: Benq broken chip
Thanks to all. Gabriel was right, I did not put the hairband over to the right enough, the heatsink is only just visible, and it def is Q601 NOT ic601, this device is next to L604 and D 601. Sorry for problem/Comment

Re: Benq broken chip
Maybe i am wrong , but the BenQ number printet on the board is
4H.03V02.A03
If so Q601 is a K3530, IC601 a 1203P60
I found this board in a belinea 2225 S1WComment
