Hi folks,
Had a lot of help from Quuq folks early this year on my lack of '5v S/by' problem with shematics and advice re- those 3 dubious diodes. Today thought to replace the STR-A6169 again - from A6169-SK631-147C to A6169-SK502-498C - set worked.
No idea why but glad it did, so but thought mention it - Thanks and now to find the customer - Chris
