LG 32LG30 intermittent gray screen when powered on, power cycling fixes it and it will run indefinitely after that. Doesnt seem to have anything to do with how warm the TV is running, ie can run for hours, then power cycle will cause the grey screen.

by usbdeviceHi all
There's two other threads about this monitor with seemingly the same problem. The problem was resolved in one case by replacing the entire PSU board and in the second one by replacing an unknown IC.

by dbuergiHi all,
I got a 16inch MacBook Pro showing 5v and 0,3a on the left ports and right side has one power cycling and one showing nothing. The one cycling shows 30c under thermal camera. Surrounding components show no corrosion or any shorts.
Any ideas what to check next? The whole board looks clean compared to the other A2141s i saw.... - Loading...
