The top cover replacement is covered under warranty. If the graphics card is integrated into the motherboard, then it becomes the motherboard problem. So I pulled the charger back out and the screen was still black. What I want to know is it the Inverter, Display, or Video card? I took my A75 apart last night cleaned out the lint and put it back together. You mention a utility to test video card memory, but I cannot seem to find it. The screen is bad on a projector too so its not the LCD thats at fault. May be your fan works only at slow speed. Most likely this is happening because of a loose part. I am not sure if the mother board died or if the video card died or if the hard drive died. I insert a piece of soft plastic between the mask and screen and slowly move it along the screen. I would probably try using the grease recommended by Toshiba. Blow it inside the fan opening on the bottom of the laptop, so the dust goes away through the opening on the laptop side. It should start spinning right away after you turn it on. It can be either black or white.
