SOURCE: My Lg Monitor wont show screen (Power Button Flashing)

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

I bought a new Dell Pc and I keep getting flashes in the upper left hand corner. How do I get rid of this? Thanks


When you say flashes, is it like portion of the screen flickers?

If the flickering/flashes starts in Dell screen just right after turning on the laptop, when you see the Windows logo or just right after you log in to windows?

Try connecting your laptop to an external monitor then toggle display. To toggle the display to external monitor you can try holding down keys such as the function keys.

If the problem persist from the external monitor it means the problem is the motherboard or the video/graphics card.

If no problem from the external monitor this means laptop LCD and LCD cable needs to be replaced.

Hope this helps.

My lg chocolate won't turn on, just keeps flashing the Verizon Logo


Flashing the logo means that the LCD is fine and kicking. You must get the phone's firmware reinstalled. The reason of flashing Verizon Logo is that it cant read or follow the instructions beyond the logo stage. So, give it the stuff to read or follow. Reinstall the firmware and you will find that everything moves smoothly.

EMachines monitor keeps flashing the On Screen Display menu.


if it is the button. you would have to open the monitor and fix it that way, and i dont suggest doing that yourself, unless you are familiar with electronic components. take it to a repair shop. call around and get an idea of who would do the best job for the best price.

Let me know :)
