Question about Televison & Video
I am not sure how to rule out the TCON board. I do have all the voltages taken from GF2 board (ZBV A1362552A)
Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Testimonial: "Are you sure it is the main board? The TV did power up again and all voltages on the power supply board were the same except on connector CN 6154, the Inv ERR and back light voltages went to 3.25 volts. Where can I get a schematic for the Power Supply board or which transistor generates the 3.25 volts."
