Hello,

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 he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues 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.

Have emachines monitor which is not coming on power button fast flicker


Which power button is flickering (your computer, or your monitor).
Here's some tricks I would try...
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 orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

My 32inch lcd tv keeps flickering it started all the sudden


TRY THIS

    • 1 Turn the TV off with the front-mounted power button, not the remote. Unplug the TV's power cord from the wall outlet. Let an hour pass before plugging the cord back into the wall outlet. Turn the TV back on with the front-mounted power button and wait until it has fully restarted. Bring up a TV channel to see if the image being presented on the LCD screen is no longer flickering. A momentary power surge can cause the circuitry inside the LG-brand LCD TV to function erratically.
    • 2 Unplug the video cable from the video connection on the back or side panel of the LG TV. If more than one video cable is connected to the TV, disconnect all of them. Disconnect the other end of the video cable from the video source device that it's attached to -- a DVD or Blu-ray player, or a satellite receiver or cable box. Blow off the connections on the video source device and on the back or side panel of the TV with bursts of compressed air. Reinsert one end of the video cable into the video source device and the other end into the video input that it was connected to. Turn the TV back on with is remote to see if the picture is now free of flickering. A loose or partially connected video cable can cause the LCD TV's screen to flicker when presenting an image.
    • 3 Turn the TV off and unplug its power cord from the wall outlet. Place a power conditioner next to the wall outlet. Plug the power conditioner's power cord into the wall outlet. Plug the TV's power cord into one of the AC sockets on the power conditioner. Turn the power conditioner on. Turn the TV on to see if the picture is now free of flickering. The RF signals in the electric line that the LG TV is drawing power from can cause flicking through interference patterns being generated.

Monitor is flickering


HDMI has the tendency to flicker on cheaper cables that don't have a strong connection. Try a different cable and see if it helps.

i believe you may have answered your own question here because what you are stating is a malfunctioned monitor if you plugged other monitors to the cpu and they worked and the monitor in question is not working maybe it was a storm surge and since it did not have a surge protector then maybe the monitor is shot and you may need to replace the monitor...

Crackling and flickering of monitor continuosly


somehow i dont think theres anything you can do for it, judging by what you said, the overload was way too much for the screen 

so, solution, get another screen, and get a decent surge protector, might not do much but it may prevent this from happeneing again

hope this helps

there are 2 types of flicker, one is the lamps that drive the display and the second is the sync signal of the video.
I assume the video sync is the flicker you see,
I would try connecting a different way to make sure it is not the tv,
connect using the aux /rca connectors to cable box.
and or connect using the cable direct bypassing the cable box.
I have seen several complaints about the hdmi cable signal being incorrect in some way,
this is the same issue that the svideo connector had in its early adoption signal was too hot or too low.
another thing to watch out for is the low light sensor on the front of tv if it gets an incorrect reading it can flicker the back light though it should be slow in doing so.
some times the flicker you see is not flicker but ac running through the sides of the picture from an ungrounded cable source.
how does it perform if you play a dvd player , with and without the cable box connected.
