|I have a Toshiba Satelite A135-S4407. It's new to me but my daughter used it for about 4 years. I installed Windows 8 Consumer Preview and it has been working very well with that OS. It had an overheating problem due to clogged fan ports, I have cleaned the ports today and the system is much cooler but still no display.|
The display "Froze" while I was using a browser (Internet Explorer or Chrome) and all I could do was a hard shutdown. After the shutdown I had no display on the built in monitor. I attached an external monitor, it lit up and after the boot cycle both monitors were alive. I disconnected the external monitor and continued to use the notebook for a while until it once again froze while using a browser. This time however the external display is as dead as the internal.
I'm pretty sure it's not a driver issue because I don't get the Toshiba splash screen or the text telling me to press F2 for Setup or F12 to choose boot options.
I'm pretty sure it not a backlight problem because I cannot see a faint image of the screen, even with a flashlight and the external monitor is also black.
I took the notebook completely apart today and cleaned the fan ports but, of course, that had no affect on the problem with the display.
Is there a display adapter I can add or replace or are we talking about a new motherboard?
I loved this machine for the short time I used it but now I'm back to my old Dell Inspiron 1505 with the not nearly as vibrant screen.
