Hello, I am troubleshooting a Sony TV with 173587112 board in it. AUO T-CON.
The TV turns on and draws 2A of power at 19.5V, backlight comes on and the center light glows white. There is no image being produced whatsoever, and I'm unsure how to test for audio at this point.
I performed a reflow on the main mediatek chip as well as the D4758 chip between the CPU and LVDS connector, the TV behaves exactly the same after doing this, no change.
It reacts to remote, I can turn it on and off with it and the white light blinks when it detects the remote activity.
I would replace this main board if it can't be repaired but I would like to know if there is a way to test if the LCD panel is good? Can't return a new board so yeah, need to be sure.
As far as I know, the TV was damaged after an atmospheric discharge event nearby.
Thanks in advance!
