    My monitor model is LG Flatron L227WTG. The monitor menu pops up automatically and keeps changing the setting by itself making it too bright sometimes and sometimes too dim.

    Any idea whats happening to these monitors?

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Contrast Ghost


This is common problem observed in many monitors compaq,HP,HCL,IBM this is happens mainly in rainy season due to moisture,by this moisture monitor button circuit get rust inside and button pad remain pressed. so it shows a strip at the middle of monitor like contrast or brightness. So this is minor problem just replace the monitor display control button sensor or circuit.Temporarily you can warm up the monitor by hanging a bulb of 60 watt nearer your monitor to takeoff the moisture.(Dont hang the bulb too near to the monitor). It definitely solves your problem.

Good Luck

Monitor display problem


It seems that your menu switch is short. If you can open up the Monitor check out the connection of your switch and the related components, clean with Spirit or alchohol, check out the switches, if found faultty replace it. That should solve the problem. Good luck.
