More likely will need a good set of new caps, abouit $15 for a kit.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on: Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed LG and other monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

It does the same with another PC?
If it is the monitor problem, more likely to be bad caps, that will be the first thing to look for first.

Please post back what you find. Pictures will help a lot.

Something in the power supply has aged to the point of no return. Take the monitor to a reputable repair person or check out my website www.micromendllc.com

First place to check will be the power supply section, check the main AC fuse first, then look for caps with bulging top or leaking liquid. Post back what you see inside so we can guide you further, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

The proper answer to your question is "it depends".

- LCD's have a long operating life compared to Plasma but they will burn out eventually. If this monitor has been used extensively then even having it fixed will not be worth it because the panel may die off in just a few months
- However, if the LCD was seldom used, then it may be worth it to fix it

- LCD panels are also known to be very expensive. If your problem is just electrical then it will probably worth fixing it.
- However, if your problem is with the panel itself, then replacing it is a better alternative because the replacement panel is very expensive and will be almost as much as a new unit.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

This could easily mean your monitor has blown , or been destroyed by maybe a power surge or power trip , if it has a warranty return too shop , and they should replace it

This may be that you zapped the circuit with static electricity and it will never work again. But just in case, check the power cord - it can work itself loose.

that blue light show and error or faulty problem internally or there a problem with in the connection or computer but first check the makers website or manual for troubleshooting.

You need to check on the input source. Double check if its powered on. If it is, check the cable connections and see if the connectors are fitted properly. If this is presumably connected to your computer, check the video card. It could be a faulty video card issue as well.

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is usually caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

it simply means that your cpu is not giving back signal to your monitor to process, in fact, it is a cpu problem that is why there is nothing to display in your monitor.

Your cpu froze because of that usb thing. the only way to unfreeze it is to manually reset your hardware in this order.

1. RAM modules. If you can unplug your RAM (memory modules) connected in your motherboard, please do it. Just unplug the modules and then plug it back in. if you have 2 rams, then interchange them when plugging it back. this will force your mobo to refresh its resources.

2. CPU. if you can pull out your cpu chip, then do it. this will refresh your cpu setting in your mobo. (mobo = motherboard)

Regards!
