Another Laptop Q, intermittant display inop prob after being dropped

[EvilHorace]

Yep, last fall I was moving it from the basement where I had it sitting on the bar, audio cable connected to the stereo down there and I forgot to unplug it (was in a hurry) and when the cord tightened up as I walked off with it, out of my hands and down it went, face down onto the ground.
That required a new HDD and floppy drive as both were dead after that. They didn't notice the dead floppy drive the first time either so that required yet another trip. I bought it at Bestbuy with an extended 3 yr warranty and no, didn't tell them that the thing fell (no obvious physical damage) so warranty has covered both repairs but it's gone for 2 weeks everytime as it has to be sent to Toshiba.
One thing that it still does, intermittantly is that usually if left on for a while, the display goes to dark (not totally dead but too dark to be seen in daylight, not useable). This seems to occur only after its been on for hours, like overnight and re-booting while being slightly bopped (not beat on too hard) is the only way to bring the display back. Re-booting without doing anything else when it's gone dark won't bring it back to life, it'll try but then go dark. I'll then tap/bop the top, next to the keyboard, re-boot again and it'll be OK for a long time. It might then not fail again for many days-weeks.
I took it with us when we flew to Tucson, AZ about a month ago and it was in its laptop bag with my other electronic devices (digi-cam, Garmin eMap, etc) and the case fell off the luggage cart at the airport but onto carpet. It didn't act up at all while on vacation and was fine here too for a while so I thought that maybe, just maybe its loose connection (my thoughts) had hopefully fixed itself but it's acted up again recently so I know the prob still exists.
When it was returned for the floppy drive replacement (many months ago), I mentioned this to them and it was typed onto the repair order BUT the guy said that they don't usually even try to do anything with intermittant problems like that if it's not presently acting up.
I think that there's a loose connection somewhere but I've never opened a laptop up. I've already checked all the obvious things that I can access w/o completely opening the thing up.
Anyone run into this before with laptops? I can try returning it to Bestbuy again, telling them that it needs to be left on for many hours to act up but that's not always a consistant thing. They'll probably do nothing again.

I have no idea but if no one else has a suggestion I'd say if it's a pricey high quaility laptop take it somewhere else to an actual full out computer store and pay for the repair. BestBuy isn't exactly the most willing to help bunch of people from my past experiences, if it's not top notch and the repair would be quite a large some of money then maybe it's just time for an upgrade... try to be more careful next time thought

It's not repaired by BB, they send it to Toshiba. It still has about 1.5 yrs of warranty so I won't pay and I'm unaware of anyone who repairs laptops locally. Any new laptop is costly btw and re-sale/trade-in is non-existant IMO.

I think my only solution is to just leave it on for as long as it takes to see a real pattern of when it fails. That way, hopefully Toshiba can duplicate the problem.

years ago i had a toshiba lappy with a loose connector behind the lcd. it would blank out completely, but when you pushed on the back of the screen at a certain place it would come back on -

the "secret" spot on mine was

facing the display
left hand side
about two inches up from the bottom and about 1/2 inch in

if i would just put my thumb on the frame and push with my fingers from behind that would fix the switch to on
