I picked up a LG 47LS4500-UD the other day with storm damage.
The power supply was shorted for the standby voltages with the mainboard connected.
Removing the mainboard and powering up the power supply gave me all my voltages. (3.3, 5, 12, and 24).
So I ordered another motherboard, and received it today, and I put it in, the standby voltage is steady, but no light on the front, and no way to turn on the tv. Now the strange thing about this is that the tv uses a touch control for the front panel, but the connector going to the io board has NO voltage that I can find going out to the board.
I can power on the ps with the new mainboard attached, and all the voltages look good, but no signs of life from the tv.
The original mainboard in the unit was a EBT62204211, but per shopjimmy, I used a EBT62204207 as a substitute part.
Thanks.
