[SOLVED] monitor keeps turning off itself

[clementttttttt]

My monitor keeps turning off itself, and the power button will not turn on it again unless I unplug the monitor, blow it, and plug it in.

Monitor Model: DELL ST2210

Check if the female port is dirty on the monitor, namely the bottom of the pit and the pins. Just flip it over and throw some flashlight on it.

If it is, then it's not only a mild fire hazard, but could interfere with power going to the monitor reliably.

Something non-conductive like a wooden or plastic toothpick and a gentle, steady hand can scrape it a bit. If it's more drastic, then a tiny bit of acetone with a tiny bit of sponge attached to a toothpick can be used. Don't use cotton, it leaves fibers and those fibers burn. Just for the sake of all we hold dear, let that thing be until the acetone has completely evaporated.

At the same time, try another known good power chord.

If it's none of this, then I'm not qualified to make a better guess and would just chalk it up as a dying elderly monitor.

There is no dust in the power connector, so i think it might be because of a bad soldier joint or broken trace on the circuit board. Turn down the brightness and contrast seems to temporarily fix the issue. Anyways i think i'll get a new monitor real quick.

the issue has gotten worse. now it turns off itself after 2-3 minutes. My hands are really painful just because I need to keep plugging (monitor just turn off itself again) out and in the power cable. I'm really going to get a new monitor right now.
