Re: Samsung 226BW No Picture

Thanks very much for the quick reply guys.



No change in voltage when the logic board is disconnected.



I'll give them a look tomorrow. Any ideas what voltages I should be "seeing" on the Schottky Rectifier?

Thanks,

Hey Guys, I have a Samsung 226BW that has no sign of life except that the power light flashes about once every 5 secs. The monitor doesn't respond to any of the buttons. All the caps on the IP baord have been replaced. The 13.5v output to the logic board is measuring 15.7v. Measuring the testpoint voltages on the logic board I've found the following:
1.8v = 1.8v
3.3v = 3.3v
5v = 0v
14v = 15.7v

There is 5v (5.42v) present on the output of IC702 (DC-DC convertor).
Unfortunately I can't locate a schematic, for the particular board, to be able to find...
