I was given a LCD screen from a car vcr system. The display needs 12 Volts
AC, but makes no mention of the mA requirements. I have a sony 12 Volt AC
adaptor that as 300 mA. Will it be damaged if the LCD requires more? Also if
I purchase an adaptor with to high of a mA value can that damage it?

I have searched online trying to find info about this particular LCD screen
but cant find any detailed info with regards to power requirements, so I
figured Id look for help here.

Thanks
