Lilliput power supply problem

**davinder** · 01-16-2005, 11:01 AM

Hi All,

I have been putting together a car pc but have run into a small problem.
Basically I have my laptop all setup with GPS etc and have just bought a 8" lilliput touch screen.

The problem is that I bought it 2nd hand and the car lighter adapter for the touch screen seems to be damaged. Why do I thinks its damaged well, I plugged it in and it started smoking so I'm guessing if it wasn't damaged before it is now.

So now I need to basically find some sort of replacement for it, does anyone know what the touchscreens power requirements are? Or even better know where I can get a replacement from.

Cheers
Davinder

use a 12v stabilised power supply for testing, or a 7812 regulator ic

800mA. That may be just enough. Check your 8" and make sure it doesn't use more than 800mA/.8A or 9.5W.

Thanx everyone,

I ended up ringing the UK suppliers of lilliput who said they can supply me with a power adapter for £7. Which is not so bad.

So have placed my order and hope to be using my screen soon and this time I hope I don't blow up the adapter.
