Hi guys,
I have a problem with this monitor and i need your help.
Is this a bad power supply, bad mainboard or bad panel?
The panel is a LG LM220WE1.
If the monitor is powered off for 2 or 3 days, upon connecting, image appears without any issue for a few seconds only.
My measurements so far:
VGL: -5.362V
VGH: 33.12V
VGH_L: 33.12
VDD: 12.70V
VCOMC: 5.535
GVDD_E: 33V oscillating with -5.3V
GVDD_O: Same as GVDD_E
VIN: 5.112V
SCL/SDA: 3.3V
Thanks in advance
