Toshiba Satellite c50d-b-13x screen gets black


Jun 15, 2016

I am not realy a good specialist in computers, I just fix them if I have time for it. So it's just a way to earn extra money. And this time I got a new Toshiba Satellite c50d-b-13x. I am not interested why the person did not take it to the warranty.

So the person took it to the repair shop, and they told him that the motherboard is dead. They asked for 250€ for the repair. Then he gave it to me. I turned it on, the screen was black, no beeps, just the power light and fan was on. I opened it, took all the components out, fitted them back, again and (i gues i pressed f1) then the screen turned on, everything was working fine! Even after restarts. So I gues the motherboard is fine if the laptop was working normaly.

After some time, when i started to delete and install some programs, i saw that the cpu usage was something around 80% withouth any hard work. And suddenly the laptop froze, the screen was showing the same picture and nothing happened. After I turned it off and on again, the same thing happened. Screen is black and nothing works. I checked the connections again, started it up, while holding F1 and again the screen turned on again. It took me into some settings, but that does not matter.

I left the PC turned off now, and I am looking for help.

Maybe someone can help me? I think this could not be related with the motherboard, but I am not sure. Maybe it's related to the cpu or something? Maybe it could be due to overheating or something...

I am sorry for my English, as I am not a native speaker and I was in a hurry. :)

Thank you!

A short update: It happened again a few times. Pressing any buttons did not work. I unscrewed the plate that was holding the cpu, putted it back again, and the system turned on again...? What the hell... Do not know what to do...

I would also go for a motherboard problem based from the symptoms that you're getting from the laptop. Here are some other troubleshooting steps that may help.
- First is to do a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If the same problem will persist do remove the battery again and connect just the AC adapter then observe if the same problem will persist or not.
- I won't go too far with it like opening the laptop for applying new thermal paste since it's still under the factory warranty.
- I would suggest contacting the Toshiba support for a repair or motherboard replacement.
