  1. When I power on my Toshiba equium a200-151, the screen lights up but no display at all - even though there is loading activity. I rigged up to my PC monitor and everything is fine - see bios and windows loading etc. Borrowed a spare compatible working screen but same problem. I'm not 100% sure if its the inverter or the ribbon connector - any ideas before I buy a new inverter? Thanks for looking.

    I would say that the video cable (ribbon cable) is bad based on what you have tried so far. This cable goes from the motherboard to the LCD display. Did you use the old inverter off the suspect Toshiba when you tried the compatible spare LCD panel?

    Yes....I was still using the original inverter to connect the spare screen, I will now try to borrow a compatible video cable to see what happens.Thanks for the reply.
