Hello all
This TV set is a LG 32LV5500 the chassis number is LT12E available service manual at Electrotanya.
Main board number : EAX64104702(1)
When pushing stby button on the remote the TV goes ON as the red led it turning white, no sound or images , back light is still OFF but working as I could force it to start, I only got a blank black screen.
then i checked the power outputs, 12, 24 and 3.5V are all ok, no have any 5V from power supply board.
If I check pin 10 of IC602 which seems to be BL-on i see 3.5V there but no reaction from backlight.
There are the tensions i could find on the coils :
L1807, L1808 : 0.78V
L1810, L1811 : 0.67V
L505 : 0.94 V
L508 : 3.34 V
L509 : 5.05 V
L516 : 5.15 V
Where is the 1.5V for the rams ?
There is an image from the board i could find on the net, except the connectors i don't have on this set strangely.
Thank you again for your great help.
