Re: Hanns-G HG281D, LCD Monitor no power
I tried a 3.3k jumper from PS-ON to 5vsb and still no 5/12/24 volts, I measured no AC voltage going to the primary winding of the xformer in the center of the board. See attached pdf pic with voltages with 3.3k jumper from PS-ON to 5vsb, the 4.89v shown is the voltage measured on the PS-ON circuit with 3.3k jumper PS- to 5vsb. The PS-ON signal connects to Q702 and it appears to function. 174VDC is measured across the large cap downstream from the 120vac bridge rectifier.
Any suggestions would be helpful, thank you for all help provided thus far.
