Hello, I have Samsung LA32D40s lcd tv with blank screen, but backlight and sound are ON. This TV have been dead before due to thunderstruck, and the repair shop replaced the lcd panel but after some time this TV malfunction again. The repair shop said that the lcd panel dead again.
Turn out, the repair shop replace the lcd panel with another compatible panel ( glass only, not include with housing and backlight unit ). The model on tcon board says HV320WXC-200_x-PCB-X0.0
I have tried to probe the voltage on TCon board, but I dont have any reference what normal voltage should be.
VGN : 2.5V
VGH : 16.5V
VCOM : 7.5V
V10 : 7.4V
V9 : 8.3V
V15 : 2.9V
V17 : 0.3V
VOFF : 7.9V
VON : 24V
DVDD : 3.3V
AVDD 1: 16.9V
Above are the voltage reading...
If anyone here have any knowledge regarding this particular panel, Would you please help me troubleshoot this TV ?
Thank you... Appreciate any help...
