« on: January 06, 2021,18:00:57 »
Hi, the TV has problems with the screen, the image is dark and undefined.
There is no VGH power supply.
With an external 32 volts power supply everything is ok.

VGH will be generated by a dc-dc converter on the T-Con. I'll upload a LG T-Con training manual to the downloads section of this forum. The principles will be the same and it may assist you.
