Look for bad caps with domed tops first, worst case will be the lamp assemblies.

Please post the model number, it is likely that the HV inverter for the back light is going out.

More likely to have bad caps as shown in my pictures here:

Turn your computer off completely and then unplug the monitor from the serial port. Wait five minutes and then reconnect your monitor and turn your PC back on and the Windows XP/Vista/7 operating system will reinstall the drivers that run your Sceptre 24" monitor.

First check the monitor sleep mode for your monitor in windows control panel, check that its not going into hibernation/stanby. if thats not it. and the monitor keeps shutting down. You may have to replace it newer models have more features and could be cheaper by saving you the hassel check newegg.com or orverstock.com

It sounds like a backlight problem. It could be a problem with the inverter board or backlight itself. When the display "blanks out," can you still see a faint image on the screen -- especially if you look at an angle with some light shining on the screen? It is usually easiest to see changes on the screen - so after Windows boots, press the windows key on the keyboard repeatedly and look at the part of the screen where the start menu would appear. If you can see anyting, then it is definitely a backlight problem.

If it is a backlight problem, you'll need to disassemble the LCD panel to correct it. Correcting it might be as simple as re-seating or re-routing a loose or pinched backlight cable to as complex as replacing the LCD panel and inverter board. There is really no way to tell over the Internet. You'll probably void any applicable warranty by disassembling the panel.

By the way -- watch out, the inverter board can generate lots of voltage and reasonible amounts of current. I've never been shocked by one, but I've been careful.

Yes the monitor sounds like it has fault in the internal board the cheapest way around it is to buy a new monitor

My monitor dose nothing, I plug it in and there are no lights or anything. Its almost brand new and seems to be dead.

Sceptre X7GNAGAV... | Answered on Mar 02, 2009


For most of the problems above you will find it is bad capacitors on the power board sending unstable power accross to the controller board.

For the last posted problem (Comment by Guest, posted on Jan 02, 2008) you have a dodgy inverter circuit that needs to be repaired.

Both faults should be fairly cheap to have taken care of at your local TV repair shop. You may need to call a few in your area not just for a quote, but also to see if they are willing to work on an LCD monitor.

Hope that helps you all =)

I am not familiar with your particular model, but I do know what the problem is.
The inverter that runs the lights behind the screen is faulty and needs to be repaired. The lights shine from the top and bottom and reflect outwards through the panel so you can see what is on the screen. If you start the computer up, then shine a bright light into the panel you will see an image on the screen, but very feintly.
This can be cheap, it can also be expensive depending on where you go to get it repaired. Call aorund to a few TV shops in your area to get a rough idea on prices.

Hope that helps =)
