Firstly check the connecting cable from the screen to the computer at both ends. Ensure that the thumbscrews that keep the connector in place are tight. Has the PC been moved recently? Any chance the cable could have been put in the wrong place? You can get the installation manual on the following link to see where that cables should go: http://us.lge.com/filedown.do?filepath=1000000757&fileName=L1750B-BF.pdf Try resetting the monitor by pressing the "Auto/SET" button on the front panel for a few seconds with the PC on. If that fails you can do a full factory reset on the monitor by using the on screen menu and navigation to the "reset" function on the setings (gearwheel) page. This is described in the manual page A12. If all this fails then disconnect the cable to the monitor, the monitor should display "no input signal" if it does suspect the PC graphics card is faulty.

there are 2 fuses -24v and 24 v normally would go out because
covergence ics failled . That would be a shutting down problem cased by missing those voltages.so you would need to replace those 5A (small green fuses) , you would need some kind of soldering and unsolderin skill) and the ics are stk392 570.two also. open the set from the fron ,taking speaker grill off and then the wood board behing (4-6 screws) you the the board in the center big metal heatsink. you would need to work from the back to repace those puppies.hdtvman

charge the battery until light changes from red to green, then when you put the battery back into the camera make sure you push the battery all the way down until it locks in place. Hope this helps

or just plug the video lead into the onboard connection (vga) if that doesnt work try hitting f1 when your pc is loading as sometimes the bios may be set to run in pci (graphics card) but will tell you at startup to press f1 to continue but you wont be able to see that message as its still in vga mode at this point ? i hope you understand me sorry lol, on my pc i hit f1 after 1 minute of loading to allow the computer time to get to the loading screen (which we cant see) then i know that when i press F1 the screen pops into life after about 15 seconds try it

Look for bad caps in the power supply section.
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, 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 ACER 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.
