Problem is that the red led lightens-up while powering up the box, but nothing els works. It flashes on using the remote though...
I think al already see the problem: capacitors C13 and C14 (10V 1500uF) on the power circuitboard are blown. This solo actually never powers down and is on std-by all the time.
I'll try to replace these by 16V 1500uF at the end of the day, see what happens.
