    Press Menu buttom, nail an a pin on the edge of the press buttom and let the menu buttom be pressed forever. This is my only solution with same problem.

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

CRT MONITOR display


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,

Appreciate the direct "Ask Me"

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.
