    Hello,

    I have a well used (well looked after) 2 yr + old M1530 with LCD screen. Everything was working fine until all of a sudden, true black pixels were were coloured lime green on the screen (Picture to come). Some of the other posts on this forum talk about fuzzy lines or dead pixels as screen faults but my searching has not yielded any information on green pixels instead of black ones. Now as I understand it, this must be some problem with either the graphics card (8600m GT), the cable/inverter or the screen itself. If I plug a HDMI lead into the laptop the output on my TV is normal suggesting the graphics card is OK. If I bend the laptop screen back and forward there is no change to the distorted image which I suppose would suggest the ribbon cable is not loose - what I would like to know is if there is a way to test the screen before I fork out to buy a new one?

    Secondly, should the screen be kaput, is there a general consensus on which is the best screen to get for the M1530 now that it has been out for a fairly long time - when I bought mine they were new so I just got the standard screen I believe. Does anybody know if the LED screens can be plugged straight in for example?

    Many Thanks,

    Laurence

    Try a VGA monitor and see if it looks the same. If it looks fine, then it is the LCD or the connection. If not, then it's the video card.

    It couldn't hurt to reseat the video cable just to be sure. Keep in mind that there are two connections, one on the motherboard and one on the LCD itself. The service manual is located here: Documentation

    It was offered with a WXGA+ LED screen, so if you order a screen with the cable and converter (LEDs have converters, not inverters), you should be fine. The part number you would be looking for should be T698D.

    Just to let everyone know if anyone gets a similar problem, I took apart the screen assembly and found the problem to be in the LCD connector - not the easier to find motherboard connector. A blast out of the dust and reconnection worked a treat - Furthermore i took the opportunity to clean the heatsink and fan and I would recommend this to anyone that is having overheating problems the amount of dust was shocking.

    Cheers
