Hi all,
I have a Toshiba Satellite Laptop, the lcd screen is very dim, you can just about see the logon screen, if i plug an external monitor that works fine.
I did replace the inverter, but that did not help.
I don't have that much experience with laptops.
Any ideas??

Had this problem twice recently. The first time it was the cable that connects the display to the MOBO, caused I think by moving the LCD out of range. Simply plugging it back in solved the problem. The second time it was the LCD going out. Pop of the front strap infront of the LCD behind the keyboard per the instructions and make sure the cable in plugged in securly. Also, and I'm sure you have already done this, check to make sure the brightness is turned up first.

The backlight on your LCD is bad. You need to replace the LCD. Can get expenive. It is definetly the backlight it has nothing to do with the plugs because the image wouldnt come up at all or it would come up distorted. definetly backlight, expecially if it works on external monitor...

Thirded. I find ebay is the best place for sourcing replacement LCDs at decent prices.

depending on the age of the laptop you might be able to just get the backlight.

Yea I saw this problem on a customers new Toshiba recently. When the LCD was 'moved' it would flicker from bright to dull. Warranty job.

Before you buy an lcd check into the inverter board. This is the device that powers the backlights. The cost of an inverter board is around 70.00 you can also have the backlights replaced by someone but I would not recommend doing it yourself it can be very difficult.
