Hi light is going dim day by day

what is that?
a very old LCD monitor
too dark
need help.
turn up the brightness , as the OSD menu
see those buttons. on front of Monitor. push them see OSD
then push brightness up.
if still dim the CCFL lamps for the back lamps are now old and DIM
as all do and are now BAD.
HP does not sell parts for this old of monitor. if bad.

this is your PS moduel in side
the lift jacks 1 runs the CCFL light tubes. for back lighting
all CCFL go dim and yellow with age.

it could be age-related but there is also a power setting in the OS. Alternately you can check also the monitor OSD and see if there is a setting for adaptive brightness enabled

Occasionally, you may find your laptop's monitor is too dim for your liking. A normal desktop computer's monitor has an on-board menu system that lets you adjust the brightness and picture control settings as you please. A laptop monitor has no such controls. You can adjust the brightness of your laptop monitor using your laptop's keyboard.

1.Press and hold the "FN" key on your laptop's keyboard. This is the "Function" key, which operates much the same way that the "Shift" key does: It allows keyboard buttons to be used for multiple purposes. It's located in the lower left corner of most laptop keyboards, next to the "Windows," "CTRL" and "ALT" keys.
2.Look at the top row of keys on your keyboard for a key with a tiny triangle pointing upwards and the symbol of a sun on it. This is the "Increase Brightness" key. With the "FN" key held down, press the "Increase Brightness" key. On most laptop keyboards this is the "F7" key, but it varies depending on the model.
3.Continue to hold down the "FN" and "Increase Brightness" key until your dim laptop monitor has reached the level of brightness you require. A laptop monitor can only get so bright. It will stop at its highest setting.
4.Release the "FN" and "Increase Brightness" keys. You have now fixed your dim laptop monitor.

I hope you find it very helpful.

I'm sorry my friend but seems your LCD monitor having problem. There are three options with your LCD monitor. Option 1: repair your LCD monitor *commonly problems are the LCD inverter*. Option 2: Replace LCD monitor with a new LCD monitor. Option 3: Instead using your dim LCD monitor plug CRT or LCD monitor external serve as your monitor. Have a nice day.

Good Morning! With the 8 years operations of your emachines monitor, some of its electronic parts might incurred cold solder joint connections from its circuit board & possibly some of its Capacitor parts are already worn-out. please try to get assistance from an electronic service technician which will surely diagnose & repair the problem. best regards.

I have exact same problem but mine happened to 2 of my x2gen monitors at the same time,really strange.
One was purchased 01/07 and the second 04/07
Took my PC in, no problems
Took one of the x2gen in,was told monitor is bad
How could both monitors go bad at the same time???????

maybe you got some capacitors dried on your monitor

Hey...Mama of many,

Try used your fingers press on the buttons on the monitor and the on screen will appeared. Then just press the next button until you reached the icon (brightness.) Next used the - and + to changed the brightness. Have a nice day!

The inverter is the most common item to fail on a LCd monitor. Capacitors usally fail the most. Are the tops of any of them popped up. If you had any shorted transistors the fuse would probably be blown. Usally labeled F1. I would replace all the capacitors first and go from there. Capacitors are cheap.
