MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...

I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.
I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue.... -
I am trying to fix my Dynex tv. The PSB is new and so is the Control Board, but when I turn it on, I get "please wait..." on screen, then it quickly goes black. I have the back of it off and checking voltages shows 5v standby and 2.5v supply comes on going away/into PSB/Control Board, 24v is present on PSB (getting .4v on most, if not all, backlight lines, 5v to backlight is there also), the control board's heatsink staying hot to the touch, plus the 2.5v going away/into the PSB/Control Board, gives me the impression it is on. What else should I check for? -

good morning, I have a samsung UE55F8000SZ tv that turns on, shows the logo and turns off after 1-2 seconds.
This defect happens continuously, hearing the classic click of the relay every time.
Power supply board BN44-00636B
disconnecting the mains and lamps from the power board always causes the same problem.
Is it normal that without anything connected this power supply turns on and off cyclically?
any suggestions on what to check?
thanks in advance
