I have this monitor which had the known issue with the corrupted flash. That is solved, now, after some time it started to cut the image from time to time and just display grayish random vertical lines. After some minutes the image usually comes back, until it does the same again.
I took it apart and the only think that I noticed was ZD1 protection diode on the TCON board reaching 90ÂșC when it's showing this erratic behavior. I measured the voltage on the fuse right beside it, and is measuring 15.3V (under load). Without the TCON board connected, the connector measures 18.3V.
The diode has 6U written on it. Do you think the diode is misbehaving or is the voltage somehow not stable?
