Do you have to remove the scan drive boards at the bottom of the tv to access the backlights.Leave a comment:

Re: LG 65UH5500 Momentary Flash Of BackLights
Have an LG65uh5500 same issue. If you disconnect the connector from the led driver board to the main board and connect your meter lead to one of the 80vdc connectors on the psu then reconnect the mainboard plug the tv in the psu momentarily flashes the 80vdc then returns to the lower,in my case 63.5vdc. I am wondering if the mainboard is seeing a defective led and returning to standby voltage. Also the led strips momentarily flash on on first powerup.Leave a comment:
