Toshiba Laptop Blank Screen on Startup. If comes on, restarts when I bend the screenscreen capture
Posted 10 June 2011 - 02:25 PM
Most of the time the screen remains blank when I turn it on, although the rest of the laptop seems to work.
No flicker or anything - just completely blank.
Sometimes the screen will come on and the computer seems fine, but when I bend the screen at all forward or backwards a blue screen comes up and it restarts.
The error messages that come up change every time, so I don't think they are relevant...but I can list them if someone thinks they will help.
External monitor doesn't help when the screen is blank...works fine when the screen works.
People have told me probably the motherboard. Or maybe an exposed wire to the screen is short circuitting other things.
I am willing to open the laptop up and look around, but obviously I'm not super savvy.
Thanks for any help..

Don't have a whole lot of experience taking laptops apart.... the lcd assembly...do you mean the whole top part of the laptop? Or just unhook the place where the 2 wires connect to the bottom part of the comp from the top part?

Assuming I didn't mess something up when I took the lcd off.... Is it probably the motherboard at this point? Any other suggestions of things I can take out?
It seems so weird that moving the screen would screw with the motherboard somehow...unless moving the screen triggers some weird settings or something...
Thanks for any help

If so, I do not see an onboard VGA/HDMI port on it so I'm assuming that the VGA port is on a small separate board that connects to the motherboard via a little cable. Look and see if you can find this cable and remove and reattach to both the VGA board and motherboard. Its a long shot but worth a try. After doing this if it still wont work out of the onboard VGA, with it on there is a key combination that is the "Fn", function key, and usually "F3" or "F4" i think, try that to see if its having trouble auto moving between LCD and VGA.

Got any experience buying motherboards over ebay?

That being said with this issue the motherboard could be the problem but I can remember a few times I just nonchalantly chalked it up to a bad mobo only to get the new one in and still have the issue. Words of wisdom, start with the most likely and cheapest part.
P.S. when buying any part on ebay, search by the actual product number on the part itself first to ensure accuracy of the part. Should be a label/sticker on it somewhere with a long string of letters and numbers for the LCD ribbon it's something to the affect of K00000XXXXXX with the X's being random numbers/letters. LCD screens tell you specifically what model number they are and motherboards should have a similar format to the ribbon for toshibas. If that doesn't pull anything up, broaden the search to your model number of the laptop and the part name: "Toshiba A205-S500 motherboard". If still nothing, search the broadest: "A205 motherboard". Just be sure to read the entire listing and make sure you know the part is in working order, from a respected seller, has some form of return, and is in fact the right part. Emailing the seller with those questions is acceptable.
Pretty much your call now so best of luck. Let me know what you decide and how you end up getting it fixed.
Hope any of this helped.
