I have a Toshiba A105-s2716 satellite. At first the screen would start flashing. The screen went black and sometimes gray horizontal lines would appear. It would then turn black and go back to normal. After a week now, the screen will stay black after ten minutes of using my laptop. It works fine with a external monitor, many people tell me that its a hardware issue. My warranty expired so I’m trying to figure out the problem before I have it fixed. I need to fixed my laptop ASAP because i need for college.
I’ve seen this problem with Satellite A105 laptops before and I believe the culprit is the the motherboard. Even though the external video works fine, it’s still a problem with the motherboard. I think there could be something wrong with the video chip or with the video cable connector. Unfortunately both the video chip and the video cable connector are soldered on the motherboard. It means the whole motherboard must be replaced in order to fix the problem.

I tried to replace the whole LCD panel, but it didn’t help. I was going to buy a new laptop, so I just wanted to mess around with the old one. First thing I did – I upgraded BIOS to most current version. I did it just to see how BIOS upgrade works, and it fixed the problem!
It’s possible that Toshiba fixed this problem with the latest BIOS release. I tried updating the BIOS before but it didn’t help, apparently the BIOS version with the fix wasn’t available back then.
I will try it as soon as I have to repair Satellite A105 with a problem like that.
