Oh Wow really,

I just assumed they were all the same. It is a Breakbox (older) model so I
would have expected it to be 
Pre Aldi. 8-)

I know the unit used to work, although I could only get B & W out of it.
Prehaps it

There is no screen now though, so something inside has died.
I wonder where else on the main board I could safely check for 9V?

Thanks.
