My Screen Is Black No Back Light Toshiba Satellite C850
Chosen Solution Even there is no display when connected to external screen using either HDMI or VGA slots. Is it possible that the graphics card is malfunctioning, can I change the graphics chip?? please advise Yes, if you don’t get any image through the HDMI or the VGA connectors, it’s most likely you have a graphic chip problem. Sorry PS: It’s possible to rework the chip, but I don’t know if it’s a patch or a long term solution....
