Re: Six Acer V173 LCD monitor all with same problem, only display Win 98 640res
FAT TAB is not GND, that fat tab and the center pin are connected together internally and they are OUTPUT pin.
You need to use circuit GND such as GND pin of the connector.
It is 3.3V fixed LDO regulator 1117 series IC, so if you look at the device with the tab up: Left pin is GND, Center pin is OUTPUT (should show 3.3 VDC), Right pin is INPUT (should show 5 Vdc)
