Initiate random startup to trigger reset Power off and restart device as needed
I received my original monitor in 2010 and it began shutting down randomly within about a minute, though most instances lasted around five to six seconds. It started after I powered on the monitor, so I thought the power adapter was faulty because it heated up quickly. After connecting the monitor cable to my variable power supply, the issue continued, making me doubt my assumption. The system runs Windows 10 Home 64-bit with AMD Ryzen 9 3950X, Asus ROG STRIX X470-F gaming BIOS v6202, ASUS DUAL EVO OC GeForce RTX 2080, and a Corsair RM750x 750W power plan (2018). The monitor model is LG flatron E2240.
This behavior is often seen when electrolytic capacitors begin to fail. The power brick may be at fault but there are capacitors in the monitor itself. If you feel at ease working with electronic components, you may give it a shot. That monitor being a 22 inches 1080p, it probably isn't worth bringing it to a repair technician (unless it has sentimental value or something). You can find equivalent monitors or better for as low as $100 nowadays. Have a nice day !
I’ll disassemble it and check for any unusual parts. That’s where I think my understanding stops. If you need, I can go ahead and upgrade my monitor setup now. Thanks for checking in—I’ll update you if I manage to revive it, though I’m not looking for much.
You can locate instructions online for identifying faulty capacitors. Signs such as leaks, swelling, and explosions are common and relatively easy to notice. Just require attention to detail. Another aspect to inspect is any loose wires or connectors; while they’re unlikely to trigger a power reset, it’s wise to verify them each time you use an electronic device.
caps look fine think im gonna have to call it dead thanks for your help tho
Noted a dark spot near the menu button PCB. Likely a spill from earlier that got splashed and ran down. Uncertain if turning it on would trigger any reaction, but I tried powering up the monitor then unplugging the PCB—it stayed on. After a quick 2-minute soak in Iso, it worked fine again. Probably a power brick issue now; should fix it.
