Hi folks,
I got this TV dead - backlight was out. Almost 50 LEDs out of 70 were charred - I don't know how it worked till it got to this point.
Anyway, replaced all bad LEDs, assembled the unit, and it worked beautifully. I navigated menus, lowered Backlight setting and went to grab a bite.. when I came back the TV had turned off, and a burn smell in the room.
Now, no STB (13 V is now 1.6 V), the large cap has 164 V on it (PFC is not on)
I'm assuming the standby circuit went out, or whatever generates the 13V? LEDs are not on with the Main board disconnected as you'd normally expect.
Any help is appreciated. I ordered a new power board - just was curious how bad this board is damaged.
Thank you
