Good day, everyone. came the little body after some kind of (twilight genius) were packed into the trash bp and an inverter.
After some (procedures), the box began to turn on but does not display a picture.
Power is supplied to the panel (12v) I
climbed a little with a tester on T-con and measured the following at the control points
VZ REF 2.46v
AVDD 15.5v
VGHP -27.5v
VGL -9.9v
VPP 2.25v
VCCE 3.25v
VSS -5.9v
composition of the device
matrix T320XVN02. 2
motherboard 40-MS82VG-MAE2L
People tell me what to look for.
