Only works as extension; loses signal when put as main monitor.

You could use an HDMI to VGA converter.

check the main earth wire near the battery. and one near the rear of the lights. unbolt them and clean the connectors up put some grease on them after. then check again. remember that when the earth wires come off the radio code will be needed to reset the the radio. be safe and take the battery off.

Have had similar problems with two Gateways that are actually Acer--both two feet away on either side of each other: one or the other will lose connection--so not the units---if move the one not connecting closer (it is 50 feet with 3 walls between it and router) it will then pick up the wireless and work fine--I answer about 300 questions here each week so end up to avoid this in the mud/laundry room where I can depend on the signal and also have a smoke if I want.

May want to as a test move it closer to the router and see if same issue or not.

No signal means that there is no communication between the computer and the monitor. Check to make sure that the cables that goes into the computer is in snuggly and also that the cables that go into the monitor are in snuggly. If the computer sounds like it is working properly (lights on, you hear fans blowing and hard drive spinning) then your problem is either that the monitor is bad or the VGA (Video) Card inside the computer is bad. If you have access to another monitor try plugging it into the computer, if it works you know that your other monitor is bad. If it does not work your Video card needs to be replaced.

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electic extensions or just replace them they are probably faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error hope this helps

Your monitor is fine, the problem lies with your computer. Your monitor is not receiving the POST signal from your computer. I suggest you remove your computers graphics card and plug your monitor cable into onboard graphics, then power up and see if the monitor gets a signal. If it does then it means that your graphics card has stopped working. If you still don't get signal then I suggest you take your PC to your local computer shop and get a qualified technition to have a look at it just in case the motherboard is damaged. You can also try out your monitor on another system just to be sure.

Hi,

While booting press F8 , Go to safe mode and change the screen resolution and reboot the system.

Hope this helps

I think the degitizer (touch screen ) is faulty.
Replace it.

its power problem

Hi Bwill,

I can't figure out exactly the problem but let me figure out On Off mode. Presumming, you have connected the monitor signal cable to PC and your PC works fine and the video card itself works fine also then the problem is on the SMPS (swithcing mode power supply) of the monitor. Try connecting another monitor if needed checking the PC is fine.

When troubleshooting monitor's SMPS let a technical guy guides or somebody has a knowledge in troubleshooting SMPS for safety precautions. There might be a shorted HOT, component problems on primary and secondary side, control circuit, feedback ckt, load problems that immediately shutsdown the SMPS.
