Re: Samsung 940BX I/P

Hey jetadm123,

Thanks alot for the info. Will repost after sucess or failure.
Another point I would like to make concerns the workmanship on that PowerNet sub board and that is the workmanship on the soldering job.
Put the board under a 30X microscope and most of the solder joints are cold and crystallized. some had very little solder on them. It reminds of the output of sodlering class for beginners.

Re: Samsung 940BX I/P

Any way I have two Samsung 940BX monitors that are dead. The culprits are the two PWI1704SV switch controllers. Unsoldered them and found two smt devices on both boards that are completely open. They are marked RA4 and RA6. Can't find a source for the sub board nor the transistors.

Thanks for the try retiredcaps

Repairing without schematics (been there done that for more years than I can remember) is ok for shotgun trouble shooting but getting to the nitty gritty...

Got an HP 1740 with the exact board playman posted the pics on. Need the schematic for 48.L1G02.A01 Benq board. That rev number at the end makes all the difference as there are subtle difference between rev numbers.. The schematics and board layouts and component designated numbers are different. Does anyone know where I can get the correct schematic and board layouts? Thank you
