Re: Samsung Syncmaster 245BW
Hi,
I got the new F9222L but still didn't get the unit to work. I also got another monitor that had a burned resistor RB805. This unit is working again. Now I have a working unit so I can check for differences and already done some stuff, but had no luck to find something. I figured out that voltage on pin 11 also is a feedback loop from 24V side. Because the faulty unit does not have 24V the voltage differs on that pin.
I'm still stuck. It seems, that somehow the unit isn't oscilating. I got high voltage ratings on primary winding. But nothing on the secondary. I unfortunately don't possess a oszilloscope to see what is going on. But with my simple voltmeter I see a little voltage on primary winding (TM801S) on the working unit and none on the faulty one. The working unit also makes a low fizzling sound that I would expect. But the faulty one does not make any kind of sounds.
Any hints are apprecitiated.
