Re: VIZIO M552i-B2
tv plugged in lcd panel connect:
HVDD, .8 mv
VCC, 3.327
VDD, 2.3mv
VGH, -202.4mv
VGL. -5.13
Look for shorted circuit on the tab bonding boards, I.E. capacitor, or COF.
You can first check the resistance between circuit GND and HVDD, VDD, VGH to see which one shows low resistance reading.
