Where do i get the flex for the screen

Sometimes the flex cable that connects the touch screen comes lose when reassembling. You will need to take it back apart and check all connections. If the flex cable is fully set then there are two things that can be wrong.

1: The screen and or cable is bad. The flex cable is very fragile and can tear easily. Inspect the flex cable for small tears or sharp folds. Also look for missing components on the flex cable.The solder pads are shiny if none was there and dull if there was something there

2: The pressure connector on the motherboard is broken or not fully seating. Look at the pins on the back of the connector to see if any part of it came loose. You may need a magnifying glass to inspect it.

If all looks well then it may be a bad touchscreen.

Toshiba is famous for overheating problems, blow out your cooling fan with canned air. Also another fairly common issue with the M4 is memory module seating, basically the memory modules/sticks werent put in properly by the factory...i know..go figure. Remove the memory panel from the back of the unit and remove the memory stick/s. Should be 2 of them, be gentle, and then just simply reinstall them back where they were making sure they are seated in the slots firmly, then replace the memory cover and fire it back up. This worked on 4 or 5 ive repaired with similar issues. Hope this helps you as well.

Doesn't sound like a GPU as the external works . Could be screen or flex cable maybe ?
