HELP! Toshiba Satelite Screen Issue

ron.atkinson  you have a problem with the backlight circuit on your motherboard. There is no inverter and the backlight is driven from the motherboard not the replacement screen. toshiba is a paranoid company that does not condone having their service manuals show up enywhere. So if anything you can try by giving us any information that is printed on the mother board. Look for makers/model numbers etc. Let us know what you find. Without a schematic it will be very difficult to determine where the fault is. Of course you do want to consider posting some good images of your motherboard with your question. Use this guide Bilder zu einer vorhandenen Frage hinzufügen for that. It will allow us to see what you see.
