Nothing happens visually when plugged in.
Holding power button same result.
Power supply generates 30V for backlight and 19V for main board.
I found feedback resistors for 19V and figured out it's correct.
On the main board, lots of other voltages are present: 5/3.3/1.5/1/2V
Panel voltage is missing (assume CPU doesn't enable it) and ON signals to PS are low (close to 0V)
CPU is warm.
Connected ethernet cable, the router doesn't recognize TV.
I suspect it's bricked or BGA, but would like to get some opinions.
If someone could share service manual, it would be great.
I did find one for E series which helped with power supply troubleshooting.
Also, can I use main board from same series, but different screen sizes?
