Question about Toshiba VGA Board Graphic Card

1 Answer

External monitor connection problem

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.

Toshiba Satellite A505 - Most of the time when I turn it on the screen is grey, with no text.


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.

Laptop broken screen... plugged in Dell monitor,still doesnt work


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

Toshiba Satelite 105 4134 Major Resolution Problems


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 laptop.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt 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 systems 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 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Toshiba satelite pro red spot on screen


Sounds like your screen is going bad or your video card is bad. Try plugging an external monitor to the laptop to isolate the problem. Borrow a monitor from a neighbor, friend, relative or co-worker and plug it into the laptop. if the borrowed monitor displays without the red spot then your original monitor is bad. If the borrowed monitor shows the red spot then your video card inside the computer is bad.

Screen is blank (no video), even when connected to to an external monitor. I presume at this point that it's a problem with the on-board graphics processor. Notebook appears to power-up normally. Notebook...


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.

External monitor connection problem


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.
I can't guide you through disemble, its complex. I can include a site to help you with this.
