Hi,

I have an HP LCD monitor plugged into a laptop.
The colour on the laptop is 100% but on the monitor its very red.

I tried replacing the monitor with a spare, but same problem.

I reinstalled the drivers and checked the settings of the monitor, but again still the same problem.

Do you think its a hardware fault with the laptop (IBM)

Not sure to call them as its an on-site warranty.
1) Its not the monitor
2) Not the cable
3) I think the settings are fine, as it was working fine on Friday, and today its buggered

Any suggestions?

Thanks!

:)
 
Sounds like a bent pin on the connector.

If it is a bent pin, be very careful when straightening it as these pins are very brittle and can snap off easily. Use a thin nosed pliers or tweezers.
 
I've seen this before a few times. A bent pin causes a lot of grief. Although it looks right, that small pin not making good contact changes the colour of the screen. Good advice from bedik ... be careful when straightening the pins.
 
I've had a green screen before (and a blue screen, since I'm using Windows :D) because of a bent pin :)
 
erm...

quoting here, but,
1) its not he monitor
2) its not the cable

the pins are in the cable, male end. the notebook has a female connector.
so if he was swopped out the cable and monitor already, then we can forget about bent pins.
 
If he tried more than one monitor with the same symptoms, then it's either the video card itself, or the red pin (on the female connector) is not either soldered properly to the motherboard, or it is not making proper contact with its male counterpart.
 
Hi all,

Thanks a lot for your advise.

Sounds like a definite hardware fault with the laptop then.
Its still on an onsite warranty, so will give IBM a call today to come and sort it out.

Thanks again!

:)

The things at the end of the CABLE are called CONNECTORS. He needs to check for a bent pin.

confuse me more, please.

as per post 1, he has tried another cable.
do you think it could be a random office worker, running around with as knife, intentionally bending all the pins in the monitor cables (the bendy thing that attatches to yoru much loved solid CONNECTOR), or could it be something more likely...like, perhpas, the fault isnt in the fsking cable/connector that belongs to the monitor????????:confused:

3 possible solutions to this

a) random pin bending kjleptomaniac works at his company...nit likely
b) bad bios version (this happens)
c) vga port, on motherboard is dud....bad solder/cold solder....etc etc....maybe even one female pin on the port is pushed back into the vga port. but you still arent going to fix that with a long nosed plier, are you???noooo....you were talking about the cable...the one he has already swopped out.

@ Student - do let us know what happens.

I'm sure it's a hardware problem.

Also had the same issue - monitor was showing blue, swapped it out, still blue. (maybe the luser watched too much pr0n? :p). Replaced the video card, everything's right.

In another case, the monitor was showing red. I always check the connector(s) first, and found a bent pin. Straightened it gently, and all was well. Happened three times so far.

Should you replace the monitor with a spare, and the color's fixed, and there's no bent pins, then one of the guns have packed up. Again, it might be cheaper to get a new monitor rather than trying to fix it (unless the monitor's under warranty).

On a laptop it's more difficult as the video card is embedded on the motherboard, and will cost dearly to repair (new motherboard). Best you can do is to buy a new laptop, or exchange it under warranty.

If said laptop's out of warranty, and it would be too expensive to repair, rather buy a new lappy, and use the problematic laptop as a small file/web server (built-in UPS).
