I'm trying to repair an older laptop (3 or 4 years old), a Toshiba A205-S4707. I've checked everything that I can check (at least what I've thought to check) and I have not found the problem yet. What it's doing is that when it gets to the Windows 7 boot-up screen everything on the screen artifacts, creating visual distortions that renders the screen unusable. The screen itself displays no artifacts when in Safe-Mode or while in the Bios. It is only when a higher graphical standard is initialized that this problem occurs (at least, that's what I'm assuming based on what I've seen).
This is what it looks like when Windows 7 starts to boot:
What I've tried:
1. Hooking the laptop up via the VGA cable to an external LCD monitor works fine, the LCD monitor has zero artifacts and looks absolutely normal. I believe this rules out the graphics chipset itself but not certain.
2. Buying a new LCD screen for the laptop - the new LCD screen didn't fix anything. The new LCD screen functions the same as the old one in that it looks fine up until it gets to the Windows 7 boot-up screen and everything artifacts (Fine in safe mode/BIOS).
3. Buying a new inverter for the laptop - replaced the old inverter with a new one that matched model/make of old inverter. Same result happened (when Win 7 boot-up screen appears, the screen artifacts. Fine in safe mode/BIOS)
Can anyone here suggest *anything* else to try? What could be causing it not work in higher graphical modes but run fine in Safe Mode/BIOS and display to an external monitor fine even in higher graphical modes?
Thanks for any help anyone can give. So tired at this point...
