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 occurr 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.

If you have another outlet to connect just do it (e.g. VGA+DVI, VGA+HDMI, HDMI+DVI). If not you have to use another videocard that supports multiple monitors.

Have you checked the settings on your TV Malik? You usually need to go to settings on there and bring up HDMI. For example, if you have TV selected on the settings, you need to change to HDMI to view stuff on your TV screen from the laptop.

How to connect acer aspire 5315 to LG led tv


Acer Aspire 5315 doesn't come with an HDMI port. So, you have the following options:
1. Use a VGA Cable to connect the PC to TV if the TV has PC-Input facility
2. Use an S-Video cable to the TV's S-Video-in port if the TV has it

3. Use and S-Video to HDMI converter if the TV has HDMI port
(http://www.amazon.com/Composite-S-video-Audio-HDMI-Converter/dp/B003NS0UUQ)
for audio, you can use 3.5mm to RCA (Red/White) connector to connect to TV's audio-in port.

On the back of your computer you should see either a DVI plug (http://cdn.zedomax.com/blog/wp-content/uploads/2008/09/dvi.jpg) or an hdmi plug (http://www.techpin.com/wp-content/uploads/2008/09/hdmi-port.jpg) if you have the proper chord, all you need to do is plug one end into the other and you should be good to go.
