Getting picture but no backlight. Getting 45v every white wire on led connector. Could it be anything else other than a bad backlight? Would assume that the 4 strips would be independent of each other.

Re: Bad vizio v505-g9 backlight or video board.
45v is the led supply, which might be high indicating an open string. There seem to be 9 led's per string at 3v each would be 27v. The 4 return lines are 0 volts likely because the led driver is in protection.
I would suspect bad led's in the panelLast edited by R_J; 07-23-2021, 08:35 PM.
