Re: samsung 226bw

Is this thread still alive? I'm having exactly the same problem with exactly the same monitor.

All the voltages are ok, except Pin 9 of the connector, which is 0.7V. I traced this back to the pin #1 of IC603 (LM393).

Now, as far as I understand, Pin 1 of LM393 should be 5V if Pin 3 (5V) is higher than Pin 2 (3.3V), right? On the other hand, the (inaccurate) schematics from the service manual show a transistor (Q700) here, which could pull it down.

Another thing I noticed is that R226 (next to IC204) is missing. It's...
