I have same problem with my previous DELL and now with my new (1550) onr too.
Sometimes when starting up the laptop with own display (not remote one, which this problem has never occured) the display just keep to be black. Sometimes it helps to close dislpay (to make laptop to go "sleep" mode and then open it up again, but this does not help always).
Maybe this is normal behaviour for DELL laptops ... This is last DELL that I bought.
Check to see if your truck was recalled for a faulty cam shaft sensor. Some sensors develop hair line cracks which allow contaminants to get in and the sensor becomes intermittent. The symptoms can include sudden shutdown of the engine so a recall was issued.
Sometimes that happens to me too. What I do is just push play, then fast forward, and normally if you watch it, the picture starts to come back. Just keep fast forwarding until you can see all of the picture, and you should be fine.
