BOUNCING CHARACTERS/DISPLAY


1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.

Blinking light on 20 inch apple display


Blinking light on Apple cinema display usually indicates insufficient power from the power supply. Test it with another power supply from ANY cinema display (23" and 27" power supplies are ok to test with).

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Power is on but after 2-4 seconds display turns off but power is still on where the power light is in blue.it's not in sleep mode where the power color is orange.it just goes back to normal at random...


Without looking at the monitor to confirm this, I suspect you have failing capacitors which power the HT circuit, simply, the power needed to light the display, is leaking to earth, capacitors have lost the ability to store the charge necessary to illuminate the screen, which is why it is working erratically.
You need to get this checked out by a TV technician.

The light on display is produced by a lamp over or under the LCD (TFT) display, or by the heated CRT electrodes on CRT display. Your lamp or CRT may have gone damaged.
