This could be anything from the monitor to bad ram or other items...i.e. software. I can't tell you what to replace but I can tell you what to probable logical sequence. First, check your connections....meaning unplug and plug in again. Next (given that does not work) switch monitors. If the bad monitor is still bad and the other monitor works on your old system that tells you either the monitor is bad or you have a problem with your old system. If the monitor is good the next item to check is the video card. First try reseating it.....reseating means taking it out of the slot and putting it back in. There are some preparatory things you need to do first though. 1) You need to open the computer case. 2) Before you attempt to remove the board make sure you touch your machine (frequently). This (more or less) puts you and the machine at the same electrical value / avoids a static discharge. 3) Removing the board means you will probably have to unscrew one screw, it holds the board in place.

Notes: The video card is what the data line from the monitor is connected to by the way. Make sure you have unplugged your computer after opening the case and prior to placing fingers inside the case.

4) Using a the eraser end of the pencil sand the gold fingers on the video card after removing it. The removal process normally requires you tilt it slightly forward and then pull straight up (gently please but with increasing pressure....a slight wiggle helps (not that kind). 5) Reverse the process (ignore the wiggle) and when complete turn it on again. 6) If you get the same result it is in all likelihood the video card. These are available for an "old" computer in the $10-15 range worst case (I assume you do not use the old computer for gaming the latest and greatest 3d stuff). or your local computer shop will have a low end probably only need 1024 x 768 resolution. And it will go back into the same slot you took it out of (probably) which is an AGP slot (and the type of video card you want).....but...I said probably. Sometimes the AGP socket is bad or the components that support it. In which case....assuming you have a PCI slot available then you would need a PCI video card instead. Is this all that is possible....unfortunately no. The clue in your sometimes has difficulty starting might lead one to wonder about the power supply (if flakey to use a tech term it could be the problem) while you video card is out....and if the other computer will accept it...plug it in there (since you are now an experienced If it works then replace the power supply....these also can be obtained from a local shop usually (unless you live in Kansas...I do for the moment) or can point you in the right direction. Since I don't know what you have for a machine you will need to check the wattage (it's on the label) of your existing power supply. The power supply is what the power card plugs into. Take a look around when you are inside the case in case you elect to replace this yourself....(not difficult as long as you label all the cables with the way they attach.....and particularly the power cable to the motherboard....if put in backwards on older machines that do not have an insert key that prevents will get one "POOF".....which translates to you just blew the motheboard and or the CPU....on the other hand you have learned and can now pick up a motherboard combo (see pricewatch for an explanation) and have (essentially a new machine)......did I leave anything out? Yes it could be a ram problem or the motherboard with bad test the ram you need to download memtest32 (just do a google search - it's free) and follow the instructions. If, having tried all the above (which I suspect you will not have to do) it still does not work then it probably is the motherboard. Morale of the story....ask a simple question and (with respect to computers) there is no simple answer frequently. Good careful and please do not forget to unplug the machine when working inside of it.

Veritcal lines across screen, audio on

Vertical lines all over the secreen denotes a fault to the connection betweenn T'Con and LCD panel. Check the flat cable {LVDS} connected in between for any loose contact. Re-seat it at both ends once, and try. If this do not help you, T'Con board itself might need to replace. If you wish to get more details about this fault, check this link. There are some posts, which have illustrations of screen shots as you havedescribed here. Pull up older posts, and compare the screen shot to that of your TVs.

Benq fp581 screen goes blank after about half a second evertime i turn on my computer.

Even thought the monitor looks blank check to see if you can see a faint image (shining a flashlight at the monitor sometimes helps). If you can see an image it could mean that the inverter board has gone bad.

I have also heard of an overheated computer causing a similar problem.

Line down middle of the screen-resolution is different on sides

Computer parts can sit in warehouses and be on trucks for a long period of time. Unfortunately that means things get banged around. Sometimes they don't even work when they come out of the factory. I suggest exchanging the monitor for another one. It could also be your video card. Easiest way is to exchange it and it's free to exchange.

Black vertical mark on computer

If it is an LCD monitor it sounds like the monitor got cracked when you moved it. Either that or one of the edge connectors has gotten damaged and is causing a dead column of pixels.

One other possibility is a bad video card or video cable, hook the monitor up to another computer and see if the line is still there, if not, video card or cable. If line is still there then there is either a crack or bad edge connector. Crack there is no fix, except a new monitor. Edge connectors can sometimes be repaired by the appropriate service technician.

Good luck

Monitor goes black, with ghost lines of white. unplug and replug sometimes works sometimes does'nt. it's almost like it's burn out, or blown. pounding on the top works great, it comes right back on. this...

Its more or less your monitor has gone bad.
To check the same , unplug the monitor from the computer , a slef test feature check would be displayed . Check if the monitor goes blank or shows ghost lines . If yes the monitor is bad. If you have got the system before 12 Dec 2005 its generaly covered under 3 yrs warranty.If purchased after that , it would have your system warranty
