I've got a Toshiba laptop; Satelite A105 that is 2 yrs old to be exact. The connection to the external monitor is experiencing intermittent connection problems. When I jiggle the VGA cable where it plugs into the laptop I can get it to connect and stay on but if I move anything it drops signal again. Same problem persists after I put in a new VGA cable.
What is the fasest, cheapest way to determine where the problem and fix it?
If you are comfortable with opening your case up you need to follow wiring from plug to system board checking proper connection to the board. If not comfortable or connections are ok then a local computer shop is your best bet.

This sounds like a bad display on the laptop. Hook up an external monitor to the vga port on the laptop. You may need to toggle the display to output to the external monitor. This is generally accomplished by pressing the "FN" key + one of the F# keys. Look for an icon that resembles a monitor or it may say LCD. If the graphics display correctly on the external monitor, then you will need to replace the computer screen.
You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8
Sounds like your screen is going bad. It's either the screen or the
video card inside of the computer, but most likely it's the lcd screen.
Try connecting an external monitor to the laptop. You can Borrow a
monitor from a neighbor, friend, relative or co-worker to connect to the
Plug in an external monitor and see if
display shows up on it. It can be any kind of monitor even the old big
monitors as long as it has a vga cable to connect to your computer's vga
port. If the external monitor displays correctly that proves your video
card is ok and your lcd screen is bad. If the external monitor
displays the same as your lcd screen then your video card has a
problem. The video will show
on most systems when you reboot without you having to do anything. Some
will require you to hit the FN (Function key) + F1 thru F12. Hold down
the FN key then hit the correct key for displaying on the monitor (F1
F12). The correct key will normally have CRT/LCD on it or it will have
the icon of a display.
will video work when first booting?? try to start in safe mode then if you have restore disk or applications disk remove the display video in hardware manager, sometimes the drivers get corrupted, thei may re-install video drivers. al so you might go into bios and check for setup defaults hope this works. have had similar situations on diffirerent systems. some laptops have a Fn key Function key so when you have external monitor up to system it switched=s from laptop monitor to external little picture on keys usually on or near function keys.
connect an external monitor on the unit and press the key combination to get the video on an external monitor this is different on some laptops on HP dv 6000 for example it is FN F4 if external monitor work the problem is with your laptop display if the external monitor doesn't work its probebly your systemboard als check your memory.
The problem is with the laptop. The femal VGA port is slodered to the motherboard. Once the laptop's MB has been removed you'll most likely find the solder holding the VGA in place is most likely cracked/loose. The fix would be to remove the old solider & apply new.
