Monitor stopped working...checked all connections...light won't stay on green. bought a new monitor to replace it and that monitor says "no signal". is this a problem with the dell computer and not the monitor?

What is the source of the TV signal? I know many monitors have a "power-saving mode" that returns the unit to standby if there is no signal coming in.

Check that the signal cables are working (try swapping cables). Make sure the source is on before turning on the TV. Press the Input button to select a different source. Make sure that the source signal is not refreshing (or synching) at a rate that is incompatible with the TV. (If your source is a PC that was previously connected to a CRT monitor, the refresh rate should be reset to 60 Hz before connecting the computer the the Pioneer 424MV.)

I hope this helps.

(Pioneer TVs usually give a blink code if there is a hardware problem that prevents it from turning on.)

check the vga cable which get loose connection then the signal from pc not recognized.

the monitor may be losing the back lite. take a flash light or bright light and shine it at the screen after it goes black. can you see a faint picture? if so the back lite has failed. usually the cost of replacement exceeds the cost of a new monitor but there are a couple of web sites that detail the replacement of the "ccfl" cold cathode flouresecent light.

Replace your monitor power cord

Check your video card connection.Be sure you have set the default monitor in the BIOS settings.If it still doesn't work. Try to install a video card because your motherboard maybe faulty.

First--was it working?
Did it suddenly stop?
When you see the LG logo, then it goes away, does the power light turn from green to amber? Sounds like that doesn't happen.
So--if you are getting a signal, you should see something.
If there is no signal, then the power light should change from green to orange.
With no lights at all, I suspect a faulty monitor.

The monitor has the problem. the message only means, the connector is not properly connected on motherboared . please try another monitor.

I am sure about this...monitor or the connector ( as u have changed the motherboard) of the monitor has the problem.

hi, there is some loose contact in the connection. Take out the cable end from the VGA socket and check the pins inside the socket for any bend inside the socket. Reconnect it, tight the connector with the socket bolts. If not solved, try for any loose solder or wire breake.
Thank you

The inverter is the most common item to fail on a LCd monitor. Capacitors usally fail the most. Are the tops of any of them popped up. If you had any shorted transistors the fuse would probably be blown. Usally labeled F1. I would replace all the capacitors first and go from there. Capacitors are cheap.

Hi Suzee,

Is the green flashing on the tower or the monitor?

If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.

Check for the power supply light at the back of the tower.

Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.

Then connect the cables and check if it is working.
