Laptop i have colour lines on my monitor it works ok on the big pc do you think it is a loose connection somewhere

Hook a spare monitor to the video output, if picture okay the LCD panel display will need to be replaced, go to www.ebay.com type make and model of laptop, refine search to screen. But if both show the same symptom it is the video graphics card.

Hi. Yes, it could be a failing LCD screen but I would suggest to check the ribbon that connects the LCD screen to mainboard and make sure that it is not damage and properly connected.

Think you have answered your own problem here. If the external screen is ok, then the fault lies with the laptop screen.
Solutions..
1.) Remove keyboard top cover (download a "how to" guide if not familar with doing this)
2.) Remove screen bezel
3.) Check the inverter connections (inverter looks like a thin tube)
4.) Check cabling from motherboard to monitor /inverter for signs of fraying, tears, bare wires
5.) Check connections of the cable for damage.
If the above are ok, then you may have a damaged inverter. In any event, i'd look to repairing the damage to the loose lid, as its putting a strain on the wiring

Looks to me like your LCD cable is loose. You simply need to reseat the LCD cable. If you needs steps to do so I can provide them just let me know.

HI:
If you can test your laptop, by connecting an external monitor to it, that will tell you if it is a screen problem, or a video problem. If you get a good picture on another display, you have a problem with your lcd or inverter.

Hello there:
i would suggest using a spare monitor and connect the cord that would normally go into a computer and connect it to the laptop and then plug in the power cord for the monitor and turn on the computer if this works and everything is ok then you know that the laptop screen may be faulty or there may be a loose connection somewhere ok?
best regards michael

Did you try a external monitor to see is it works mine is doing the same think so I hooked up a external monitor and the computer is booting correctly i had to hit fcn and f5 for monitor to display. I think it might be a loose connection in the laptop.

No it's not motherboard problem u have to change monitor!!!

First make sure everything else is getting power and operating okay, and that it is only the LCD display that is non-functional.

If you get no video signal or power at all, even at boot time, you probably have a dislodged ribbon cabling or power connection. Usually when LCD monitors go bad they show colour banding or all white, etc., but usually continue getting power.

As a last resort, try disassembling the lower case (with the power disconnected and the battery out of course) to expose the LCD monitor mounts, and then following the wiring from the screen into the laptop and check for anything loose or disconnected. You could also have a loose ribbon cable going into the LCD array, which will require disassembling the LCD cowling and mounts.

If you are handy and comfortable with electrics and find nothing loose, put the battery in and test the power line going to the LCD backlight, which should be getting above 7V (I think). Below that and you either have a bad video controller or bad wiring/solder joints somewhere. Otherwise, if the unit has been dropped or had a hard life generally, it could also be the connections between the LCD connector bus on the monitor array and the array itself. As a last resort, try unplugging and reconnecting all ribbon and connector cables, cleaning the exposed brass coloured runners lightly with rubbing acohol or even a pencil eraser.

Good luck...

Hello. If the problem occurs only at some times (even permanent), this may indicate a faulty connector between the lcd display and the motherboard. It should not be an expensive repair unless there is something rong with the video chipset itself, but this in pretty unlikely. Try to move the display, bend it a little, watch out to see if any thing happens to the pink line, even a small change in colour, size or whatever. Or if you are willing to do this, I could assist you to dissasemble the laptop and check the connections yourself, but I don't recomand unless you have some experience and the basic tools.
