Sorry the 2nd photo is blurred the one with the plugs in the right hand side

Customer: replied 2 years ago.

don't you have schematics?

Hi Tedd

Yes but they change the specs which is why their may be upto 6 different versions of the powerboard and mainboard

OK you need to replace the mainboard now like I just said you will need the partnumber found on the mainboard itself and post it back here the mainboard is the one with all AV connectors on

Customer: replied 2 years ago.

Thanks Anthony,

The number is XXXXX (3A)


what is the cost and availability ?


Regards, Tedd


I am not finding it in stock at any of my usual suppliers I was expecting the cost to be about $100_$120 seemingly its nearer $180_$200 I dont think that price is fair

I havent tried ebay yet I usually use I am aware of an equivalent but I dont know the partnumber at this time
