I do monitor repairs, on some other models, i change the 7805 5volts regulator that feeds the microprocessor chips, and the problem of osd displaying is fixed, but on this particular HP mx705 crt monitors, it has no 7805 regulator, but a transistor that is regulated by a zener diode.. will try to replace it and its corresponding filter capacitors..if the problems is fixed..i will post the results..

Cannot adjust the brightness and the contrast

Thank you for your query

To rule out vga card issue, please can you try plugging the monitor into another PC, if it works in there then it is your vga card at fault and this will need to be replaced.

I f however the moniotr does not improve then im afraid your monitor is faulty, when the monitors go dim it is genrally the inverters that are faulty

Please book the monitor in for repair/replacement

If this has been useful please leave positive feedback/vote/testimonial as this will help me greatly - Thank you again

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
