Good day guys
I picked this TV up from a friend.
When you switch the TV on, the backlights switch on, and stays on. However there is no picture. Sometimes a small band on the top of the TV can be observed, about 1cm thick, and when the Home button is pressed, you can see the band changing, suggesting a change in the item displayed.
My first thought were T-CON. I removed one of the bands going to the panel, and half of the screen lights up slightly, same result with other band removed. The voltage going to the T-CON however is only 10.02V. The T-CON fuse is functional. Voltages on both sides are 10.02V. Voltage at Mainboard LVDS connector is 10.02V (Ground probe on chassis)
I could confirm the voltages as per P201 exactly as in the legend on the PSU. 12V on PSU going to Mainboard reads 12.01V
Can someone please confirm my suspicion of a bad Mainboard, or can you suggest further tests I can do.
Thanking you in advance
