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

Thanks

Regards, Tedd

Hi

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 shopjimmy.com I am aware of an equivalent but I dont know the partnumber at this time
