OLED tv
Question... how do you test the panel to see if it works.
Can you use the same concept using a backlight checker for leds... I need to know how to put power to the panel.. thats all with no main board
thanks -

Re: Lg oled55e6p-u.auswljr
Performed dirty test with jumpers in and power on
and Drv_on wire terminated at MB socket halfway.
Test 1 all voltages the same on P2300 power supply
Test 2
24v on P202 on power supply
Light bulb test.. light was bright and remained on
so do you suggest a new main boardLeave a comment:
