First check for a LED indicator? if there is one is it changing when you turn on your monitor? if there is changing light then the problem might be on the power supply or maybe on the LCD lamp. To check the power supply check for a defective fuse a defective fuse has no reading on multimeter and the o.k has 000 reading. the LCD lamp power supply can be converted into different power supply. hope this may help you.

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

The only thing that comes to mind is pushing the source button on the monitor, or finding the source option in one of its menus. If it is on analog and is not displaying an image, you may have to switch it to Digital or DVI, depending on what type of cable you're using to plug it into the computer. Though this is usually auto detected by the monitor when the computer is turned on, unfortunately there aren't many options when dealing with a monitor that refuses to post an image.

You should try this monitor with another PC to make sure it is not the PC problem since you replace the hard drive but you may have not installed all the drivers for your PC hardware.

You can adjust the brightness with the on screen display controls. This link will get you the manual.

this sounds like the internal power board or video board has gone bad, the capacitors have probably gotten too hot and started to leak, like an old battery (they contain similar substances), when cheap capacitors are used this happens sooner rather than later, just like when you use cheap batteries. this could be fixed easily if you are good at soldering, otherwise you should send it to be repaired professionally.

The data cable is probably at fault. Try to change the cable.
If the problem is not solved, then the fault is your video card or monitor. To find out who's at fault prove another monitor.

If I could be of further assistance, let me know. If thishelps or solves the issue, please rate it and give a testimonialfor my response.

Just glowing screen and no on screen setup menu either?
It means that the LCD panel T-CON board (on the LCD panel) is not getting the 5vdc from the logic board or the ribbob cable came loose or it hac blown sruface mounted fuse on the T-CON board.
