All he wants to know is how to remove the back and we get totally irrelevant replies e,g, how to swivel the monitor on its stand, ridiculous !

is there a fuse inside a lg monitor

First thing, try to connect the monitor to another CPU and see if its gonna work. If it doesn't, then this might be a capacitor failure. One of the capacitors in your monitor that are responsible for holding up power for proper display is faulty. A faulty capacitor is either bulged(with a hump head) or burst. This causes the monitor to go off a few seconds after you switch it on because the capacitors can no longer hold power long enough for your display. One way to work this around is to take your monitor to a Computer Technician to open it up and probably replace the faulty capacitors

This a power failure normally caused by a capacitor failure. Capacitors in this case might be leaking, barged (instead of a flat head, the capacitor has a barged top). When you switch on the monotr, the capacitors are supposed to hold the power enough for the proper display on the monitor. In your case the capacitor(s) are malfunctioned.That is why they can not hold power for more than 5 secondsSolution:Get a sharp and flat tool and open the monitor (starting from the bottom) working your way round to the top. You will notice finger-like clips that hold the covers together. Once you have opened it, check on the electronic board where you connect the power cable. Notice any barged-head capacitor, or leaking capacitor(s). If you find any, they have to be replaced. Get a Technician to do this for you if you can not.

You have bad LCD panel and it will get worst with more lines appear.http://s807.photobucket.com/albums/yy352/budm/LCD%20panel/ Basic troubleshooting guide here: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide http://www.fixya.com/support/r6150077-basic_lcd_monitors_troubleshooting http://www.fixya.com/support/r7406380-tv_training_manuals Failed TV and Monitors pictures: http://s807.photobucket.com/albums/yy352/budm/ Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Parts: http://interliquidparts.com/ Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.

That means the monitor has a problem with the Capacitors. Capacitors inside your monitor can no longer hold up power long enough for your display. This is so because the capacitors might have been blown. This makes the monitor to go on for about 2 to 3 seconds then it goes off.

The solution is to change the capacitors from the board (the part that you connect he power cable). This must be done by a Computer Technician who will safely carry out the procedure. Open up the monitor, using a flat blade and try to separate the cover with the LCD, starting from the bottom, working your way through around. Before you do anything, check for any burged or any with a black smoked colour capacitors...If you find any, then it has to be replaced

It looks like you didn't notice the buttons, there should be three buttons on the right pane of the monitor (vertical and when you look at the monitor, they are on the right-hand side), or at the right side panel, which isn't visible from the front, you have to look at them from the right side. Refer the screenshots below (buttons are highlighted):
Front



Right Panel



Hope this helps, let me know if you need further help.
Good Luck.
Thanks for using FixYa.

Inspect the power supply caps first: http://s807.photobucket.com/albums/yy352/budm/LG/
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 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.

I had the same problem with my monitor, the problem was that one of the "pins" or "prongs" was bent and mashed flat on the monitor's port plug in cable (the cord from the monitor that plugs into the computer's monitor port). I carefully pried up the prong and straightened it out the best I could and that fixed the problem for me.

If the repair is not serious, your LCD may be able to be repaired. Sometimes replacement parts and labor for broken LCDs are often more expensive than the cost of a new monitor. If you really want to repair it, replacement screens, power supplies and control boards can be ordered direct from the manufacturer. Here is the LG Support Site: http://www.lg.com/us/support/product/support-product.jsp

Check this first:

• Remove the power cord from the wall outlet, and the LCD unit, and reconnect the power cord. Try powering on the unit.
• Disconnect and reconnect monitor video cable.

Unfortunately not. If you are talking about what i think you are talking about, then you will not be able to find that number if it is burned away. That number is either a unique production batch number or a manufacturing date, either way, if it is burned beyond recognition, then unfortunately, that number is forever lost. If you are searching for a replacement chip, however, i have found one online; you can use this link http://www.donberg.ie/catalogue/semiconductors/semiconductors_tda/tda_16846.html

Here, this forum will be of some assistance

Rate if you like!

If the power light remains on after it goes black, the problem is the inverter board that powers the back light behind the screen, the cause is usually bad capacitors. To fix it, the board must be replaced or attempt made to repair the inverter board.

You will need another box to convert the output signal from Sky box to VGA output to feed the monitor. Juts Google ' Video to VGA adapter'. For example:

http://www.thenerds.net/STARTECHCOM.StarTechcom_Composite_and_S_Video_to_VGA_Video_Converter.COMP2VGA.html?affid=8&productads=1

You may also need a good set of powered speakers for good sound.

Please leave rating if it helps.

The cable could be bought from any computer spare parts shop, however the pins layout of VGA cable shown in figure below

Hope this helps

It does the same when hooked up to another PC.
If it is the monitor problem, then you should read my guides first and look at the pictures of failed LG and other monitors.

You may have gotten a virus that is preventing the Windows Boot / Startup from running. If so, the only way to fix it without too much experience would be to put your original Windows CD in the drive and then power off the PC by pressing and holding the power on button till the power light goes out. Then power it back on. If I am right, the PC will come up with a screen that gives you the option to boot from CD. If so, select that option (be quick - it times out in about 10 seconds). When it boots up, it will come up in maintenance mode or "safe mode". You may need to get out your PC Manual or Windows Documentation to be able to use this. But if you see an option to "repair an existing Windows OS" or "Restore to a previous time" option. select one or the other and follow the prompts.

If on the other hand the PC does not come up with anything but the black screen again, you probably have something in your PC that has gone bad, like maybe a memory board.

Best of luck. If you can't figure it out from here, you will probably need "expert" help.
