This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's most likely the problem. You can confirm that it's actually the monitor and not your computer or the cable by plugging in another monitor if you have one to try. If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old your monitor is, and how much you've invested into it, you may find it better to just replace it with a gently used one from ebay.

My LG TV set (LG brand) has a black thin double horizontal line at 1/3 of screen from the bottom,how to fix this?


If this is a LCD or LED your panel is bad. If it is a plasma you have a bad driver board, ribbon connection to the driver board or a defective panel. Panels in either case are not worth replacing.

Replaced digitizer now black screen only


If the LCD was working before replacement, the most likely suspect is a loose cable connection. It is also easy to crimp those tiny flat cables, or to break the locking mechanism so the cable can work its way loose. Sounds like you booted to a black screen after repair, so I would walk back through it and double check every connection, then look at all cables closely in bright light and with a magnifying glass, to be sure nothing sustained damage (twist, crimp, etc.). Remember to check the power cable to the LCD, as well. No power, no backlight, no video.

LG M227WDP turns black a couple of seconds


Do you have the "sleep" mode turned off on the computer?
As well, you can try different screen resolutions and refresh rate settings on the video section of your computer. That might make the connection to the TV more stable.

I double clicked an icon and the screen went black.now on srart up the screen goes blank after power saving mode


Try it on another PC first, if it still does not work then you will need to open it up, most failures are in the power supply section due to bad caps (leaking/bulging tops)

Have LG 42 inch plasma, 1 inch black line down center of screen, picture good other than black line blocking center of screen, comes and goes sometimes


Sounds like the middle scalar board is defective. Since the issue comes and goes it could just be a loose connection to the between the scalar board and the PDP Module (plasma panel).

Great caution needs to be taken when checking this connection because it is a ribbon cable connection it and needs to be put in correctly aligned or it could cause a short in one of the circuit boards.
