LCD Inverter Toshiba Satellite U300 U305 U405D

I ordered this item because the screen of my laptop had become too dimmed and barely readable. After extensive online search I found this Inverter was the faulty part.I searched Amazon for Inverter for Toshiba Laptop U300 and this item came up. But, after ordering it I found out the item part number (code) does not match the item part number (code) of the Inverter on my U300 Toshiba Laptop. So I doubt that this item would be compatible with it. I have not received the item as yet so I cannot say for sure.Shipping: I chose expedited shipping because I was on a trip to USA and I was departing 4 days after my order. When choosing expedited shipping it stated that I would receive it next one or two business days. But, It was not delivered before my departure, and I did not receive it on time. So, I had to have my roommate to forward it to me in Canada, but I have not received it yet.****UPDATE*****I just received this inverter today which was forwarded to me by my roommate. And, It worked! Although the part number is different, it turned out it is compatible with my Toshiba Laptop Satellite U300 and the screen is as bright as a brand new screen again.So, I added three more stars, and just have one star removed because it was not delivered on time, although I had paid for expedited service.
