A cigarette lighter adapter is available through amazon.com relatively inexpensively

these adapter pin is available in all electonic shops and you can get them to suit your TV .
If you want the DVD to work in the cigarette lighter socket then attach the make adaper to the set with the correct polarity.
If you want to use it at home then you need the dc adapter with the current factor of about ( 12 V/5Amps) to suit your set.
I hope that is what you meant.

Your power adapter for the car is not working. Check if there is any voltage output while plugged in.

What about a small, light power inverter, that plugs into your cigarette lighter in your car, and has 100 Watts available?

(Your laptop won't EVEN use 100 Watts! Look at the Ac adapter. (Charger)
Read the specifications on it.)

have you check the polarities?or fuse?
