Screen won't turn on

You can try to do the monitor self test.
Monitor Self Test:
1. Physically test the monitor autonomously from the computer.2. Switch both the monitor and the computer off, and then disconnect the VGA cable le from the computer.3. Turn the monitor on, pressing the power button for about three seconds. The self-test screen will come up .4. If the image is clear, bright, and shows red, green, and blue, the monitor is working properly. Video issues may be due to the video resolution in the computer, and not the monitor.5. If the image is not apparent and intense or the colors are not accurate, then the trouble is with the monitor or some of the (OSD) settings. In this case, test your particular monitor's information for OSD.
It is always important to check the color of your power light for so you can distinguish if the monitor is defective. Getting red lights on the the power panel states that the power section of the monitor is faulty.

How do I connect a wii to the plasma monitor 42hdm12

This TV has both Composite (Red, White and Yellow) plugs and Component (Red, Green, Blue). Either are acceptable solutions, although ideally purchasing an after-market Component Video cable should yield the best possible picture quality.

Can i connect a regular dvd player to a hitachi flatscreen hdtv?

Yes you can. Simply connect the appropriate color inputs.

If you use red green blue for video, and red white for audio you will get the best picture

If not stick to yellow for video and white red for audio

Just remember color that is on the back of dvd goes to same color on the input for the tv

My monitor is blinking but display is nit coming

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.

Monitor does not sutn on, power button flashes four times fast.

Sorry I know your model number and its a Power Down trouble with the Scan IC's that are in the unit. You need a tech to look at it and he will most likely find a bad Scan IC and it will need to be replaced. This a is a relatively easy fix for him.

I believe that your satellite receiver should have video/audio output, if so; connect a yellow, red and white cables from there to the input on your plasma monitor and select video on the plasma to get ti to work.
Let me know if you need further assistance.
