Hi,
It may also be a firmware problem.
The logo showing is a good sign as it shows that the basic fundamentals are there i.e. the screen works, the power works, the connection between the mainboard and the screen works and parts of the mainboard work as well.
I cannot find a firmware download for your model but if you happen to find it and since you said that you’re going to scrap it if unsuccessful you have nothing to lose by trying to reinstall (or maybe update) the firmware.
If you cannot find it either try contacting Toshiba tech support in your location and ask them if it is available.

+Hopefully you are able to reinstall the same version software if that is all that is available. Some brands only allow for updating and not reinstalling the same version. Don’t know about Toshiba though.
