I’m happy to assist further over the phone at https://www.6ya.com/expert/joe_8b8c2cd6ce148309

unfortunately older models such as the a105 do not have a recovery partition. however recovery cd's are around 25 dollars if you contact toshiba directly

Here, I found this:

If you pull off the top part where the speakers are above the key board your monitor might be unplugged. i had the same problem with one

Yes, a new Hard Drive is not parititioned or formatted so you will need the start up disc to partition and format the new hard drive for it to work

Try connecting an external monitor if this also shows a "bad" picture then probably the graphics chip on the laptop is faulty.

There was a hardware failure / problem on your laptop. If I'm not mistaken it's probably on the Memory Module.

Thanks,

Don't forget that there is a switch that toggles the display from internal to external display (possibly Fn+F5).
