How exactly did you replace this screen?

It could possibly be an issue with either the cabling or with the integrated graphics.

You could probably have a new cable installed fairly easily, but I'd suggest either sending it in to Toshiba if the laptop's under warranty or having a professional take a look.

If it's the latter, It'd likely be cheaper and/or easier to buy a new laptop...

Hi I work on laptop all the time, It's kind of my little specialty, people bring me laptops when someone recommends me because when nobody can figure out what is wrong or they are to afraid to do the work. I approach laptop repair like a mad scientist,
that's how my friend describes me anyway. Okay enough of my rambling ;-)
1. what type of Toshiba is it?
2. did you use the same cable that go from the LCD screen to the laptop?
Depending on the year of the laptop there are inverter boards, they are usually about 3 or 4 inches give or take a few. it's possible that that has gone bad,
3. do you have the screen to shut off after sitting unused for a certain amount of time?
I have seen in older model laptops that have a little button or my like a little plastic pine that sticks up by one of the hinges, sometimes the switch can go bad and the easiest fix is to open up the main chaise of the laptop and disconnect the cable. a few times I actually had to take the little switch apart because it was solder to the mother board. if that was the case I'm sure I could try and talk you threw it.
But Please, If you are able to resolve it on your own please let us know so that others maybe able to learn from your experience. even if it was something you may be embarrassed about because is was something so simple because we all make mistakes, and sometimes it the simplest things that are over looked. Just to give you an example of one of my own, I soldered a new power jack in some ones laptop that also had a plug on the other end that plugged into to motherboard, well I forgot to plug it in. I just hung my head in embarrassment and chuckled and said sorry, But I didn't charge him to take the whole laptop apart again since it was my silly mistake. but hey that's how we learn, that's what I try to teach my two kids, if you don't try you won't learn, even when you screw up you still learned something, to not do that ever again.
Okay I'm finished rambling, sorry for that, It's 12:38 and I still need coffee, can't seem to wake up fully yet.

Watch the screen when it goes black then move the lid slowly back and forth to nearly closed position. If you suddenly see something on the screen it means that the cable is faulty around the hinge - fairly common due to usage. Also the connectors at either end could have worked loose.

As it works with an external monitor I rather doubt it is the graphics module.

Always pop back and let us know the outcome - thanks

The IT guy in my office replaced the screen twice; I haven't been able to leave it with him to fix so I thought I would see if there was anything I could do. Thanks.

Hello:

Can you talk me through your solution? I don't care if it's something simple I just need the screen to work so I can take it with me to court. Your help is greatly appreciated.

Thanks for the response; I tried that and it's completely black. The computer itself is fine because it works with an external monitor.
