Have a problem with my monitor and hoping to receive some help.
Basically what the problem is that i have a BenQ FP241W monitor that only displays vertical coloured lines. When i switch the monitor on i am instantly greeted with the lines. This is the case on any PC or other device i connect the monitor to. I have connected the monitor to two PCs via a VGA cable and my blu-ray player via HDMI. When attached to my PC, the colours/lines both change depending on what is on screen(the lines are not set). Same goes for when attaching it to the blu-ray player, in this case however you notice the moving picture, nonetheless the display is still dominated by lines.
This issue has been a problem for other 4 to 5 months now. Before, i use to be able to bang the monitor on the side where the buttons are located and the display will show up as normal. That does not work anymore. Also, in the past i use to be able to leave the monitor on a while (20-30mins) and the picture would eventually show up as normal. This is not really the case anymore, up until a month ago i would leave it on for maybe an hour and it would display as normal, although recently i have left it on for maybe an hour and a half and the picture will not show up.
I've opened the back up and looked at the connections to see if any have come loose (i thought the banging solution may have suggested a loose connection somewhere) but they all seem to be ok. I have also looked at the capacitors to see if any have blown but no problem there either.
Does anyone have any ideas on what it could be and what i could try? i really do not want to toss this monitor away. Buying replacement panels etc is not really an option.
Pictures below (sorry about the flash):
Btw, it's not always dominated by blue.
Anyone with any ideas? All help would be much appreciated.
