Re: Samsung Syncmaster 225BW

Just repaired my 225BW- Symptoms at above: quick flickerning blue LED, nothing more.
Changed all Caps- nothing better. Voltage output from the Switching was at 4,5 Volts- should be 13 Volts! So- I changed the SD439 (programabel Z-Diode)- now its running allrigt! So watch out for this little TO220-circuit!
