TV dead otherwise but when you power on with remote, the LED comes on a few seconds then goes out (protection I guess). Swapped other boards, new PS board 09-70CAR000-00 has to be the problem. There's no LED voltage at the LED supply connector, the other voltages at the other DC output connector are fine when the 3 "on" control lines at the connector are set high to 3.3v enabling their outputs. Checked for obvious shorts or opens, found nothing. I'd troubleshoot using the IC part numbers and work from there, but can't read 2 of them, obscured. New board is on its way, but want to fix this board to keep as spare. Should be able to fix this if I can get a schematic. Looked everywhere but can't find a schematic or repair manual for a Vizio E701i-A3. Can anybody help release a manual from the tight grip of the web? Thanks for any assist.
