17" HCL monitor,the menu buttons are not working and the menu screen comes and go automatically without pressing any buttons,like contrast will increase,sometimes brightness will become zero.

buttons are not working perfect.therefore pressing automatically. you have to remove the panel after power on the monitor, (it may be dangers therefore get support by electronic technician , he will remove buttons and solder new ones or replace the switch panel.

What is the reason without me pushing any button or anything the contrast/brightness menu comes up on the screen?

my hcl 17inches monitor is displaying contrast,brightness etc automatically
in the middle of the screen.even if i press the menu buttons it
disappears for a sec and comes again and again.what should i do to
solve this?

Actually the button for setting the contrast is a bit loose thats why whenever their is a **** os little movement in the moniter opf ur PC then the contrast button get pressed automatically and the pop up comes up

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

Try to wiggle the cable and see if it goes away. Seems like a loose connection somewhere. Try to factory reset the monitor from the menu.

hi im josh in cebu phils. Maureen may i help you? If it happened yesterday that the contrast box keep on coming. there's a problem in your monitor.so try to check the buttons if covered with dust cleaning may solved the problem.Maureen if you have the manual use it in adjusting the resolution and if you dont have try to press the button mark + or increase just press both of the to the brightnest as posible so that you may be able to proceed another action. thats all for now.hope i helped you.good luck.

It sounds like this monitor may have what's called the "Windex syndrome" in TV repairs. If someone cleans the screen with a spray cleaner and it drips down the face, it can get onto the circuit board and cause intermittent button troubles. Sometimes it's possible to clean off the corrosion from that area, but the most reliable fix is to clean the board, replace the switches, and remove, check and if necessary replace any resistors connecting to the switches.

Hi again,

It would seem that you posted your problem several times. As stated in my proposed solution in your other postings:
Unfortunately, an HCL HCM782M monitor is an unknown model. However, on similar instances and occurrence of this problem, it would seem that the controls are damp. Specifically, it would be the internal contacts of the buttons. Pls check if you can dis-assemble, remove the board/control/buttons and perform cleaning. Pls pay particular attention to the rubber pads or the small buttons themselves. if I may ask, any recent continuous rain? If yes, this may have contributed or caused your problem.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
