Did you open it up and inspect to see if you can see any caps with bulging tops, check the 5v and 12~16vdc voltages?
If you are going to DIY 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 SCEPTRE and other monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also.

The monitor is this old will more likely to have bad DC filter caps in the power supply by now. Does it do the same with other PC?

More likely to have power supply problem due to bad caps, that will be the first thing to check.

The monitor is not getting any "signal" from the video-card.
Check that the video-cable is connected to both the monitor and to the video-card.

Try connecting the monitor to a different desktop/laptop,
to see if the monitor works "elsewhere".

Try connecting a different monitor to your desktop, to see if the video-card is the problem.

press the button menu and select the rotation adjustment.

This normally happens when display resolution is changed to higher resolution and cannot be compatible/displayed by monitor. Either plug in another monitor and lower down resolution or Press F8 and go to advanced boot option and start your computer in safe mode and try changing display resolution. If it still doesn't works and you have the drivers for you display adapter (video card) then uninstall display adapter from device manager by booting in safe mode. Once you get to normal boot mode reinstall drivers for display adapter.

You need Composite video to VGA adapter box.

Hi there this mean the your monitor had an over flow of current which damage the monitor you will need to identify which component is damage and replace it. Here is a link with can give you step by step guide to open and check for the damage part.http://www.bit-tech.net/hardware/2006/03/20/how_crt_and_lcd_monitors_work/5 or you can replace the monitor if you choose to.

first check the cable ...there can be always something wrong with them ...second..to be sure that the monitor is to blame ...hook another one to the computer and see if it works...also ...you may tell this if the actual logging sound is heard when you open it ...but even in this case the computer nay be ok ..and you just messed up the video card ...setting s..or the video-card itself....so ..either trying another monitor(even an old one ..just to see if it is th monitor to blame or the computer ) or try the monitor in another computer ...(if you have a laptop you can hook it as second monitor ,, and press Fn -F4 to activate it ..)
i fthemonitor turns up to be ok ...the issue is in the video card ...
first open and see if the card is proper inserted in the slot...push it down a little ..or get it out and insert it again ) ..if this will not brink it back ...try the on board card ...if the computer has one ...but for this to work you have to remove the pci one ..) ...there may be the case thet you tried some settings that the computer do not support on the card ..and now you will actually need to insert in the on board card ...and remove the video driver ..insert the other card again ...and reinstall the driver ...I did had this kinda problem with a video card ..and I meesed some settings on it ..and it shows up black after reboot..removing the driver it was te only way out than ...and my lack was tat I had a on board card ...if you do not ...and the monitor seam ok ...you will have to try to reinstall it ..I mean the computer ..

if you have the warranty, return it and get a new one free. ok

rons1photogr, You will need to fix thermal intermittant solder joint and /or bad electrolytic filter capacitors on printed circuit board called "switch-mode-power-supply"/"CCFL inverter supply"???? Software can't fix this problem!!! Hardware refurbistment only. READ, READ, READ, more stuff in my profile on black screen repair s and or other options open to you. 12fixlouie

Start looking at the power supply for bad caps, see some example of a couple yeras old monitors that failed due to cheap caps being used: http://s807.photobucket.com/home/budm/allalbums

fried repir or replace

Hi,

Just go to this link for the same.

Thanks

If you can make out a faint image then the fault is a backlight problem.
The fault could be an inverter board or the CCFL lamp/s

A little late but hey better late than never. I assume you have the screen assembly out of the plastic housing by now. The bar with buttons actually hides two out of the six screws that hold the monitor brackets in place. Pretty straight forward. Once you get the screen separated from the plastic junk, take off the thin metal protector in the centre at the back of the screen which hides the circuit boards. Should be just one screw and then slide the cover off. Make sure you disconnect the one electric connector that protrudes through the cover on the side before you remove it. Do not pull the wires, use a needle nose pliers instead. Underneath the cover you'll see two circuit boards, one with surface mounted ICs and one with capacitors and coils that the power cable attaches to. This is the board that needs repair. On this board are 4 small capacitors in a row in a small seperate section of the board. Two of those are a little smaller than the other ones. Hopefully you know what a capacitor looks like. These capacitors are rated as follows: two 470uf/25V and two 1200 uf/10V the 470s are the smaller ones. You can take the board out, make sure you disconnect all plugs and take out all screws, mark were they came from or better, take a picture if you are not faimiliar with this stuff. Then either replace the capacitors yourself or have somebody do it. The parts total about 4 bucks. Desoldering is tricky so of you have never done it, better not attempt it, get a pro to do it. When done, re-assemble in reverse order. Good luck.

What type of video card do you have, sounds like it could be several things at this point. I recommend checking you have the latest video card drivers, and that your video card is being kept cool, as well as the inside of your PC case.

Have you tried any other monitor connected to your computer since your current problem? Check your connections, make sure your VGA cable/DVI cable are in good condition. If none of that works try to RMA it to sceptre if your still within the 1 year period.

FIXED!
Device : Spectra X20WG-Naga
Problem : monitor comes on then flickers then goes off
solution: Replace Capacitor C101 (150uf, 35V) and Fets U101 and U102 (4511GM)
Comments: This is a common problem with this monitor.
