I have a VSX-108 and bought it used. It works great except when you turn it off manualy. I do not have the remote. When you power up hours later it does not retain the stations that I set up in memory. I tested the preset station prior to turning off to ensure that it took. I then powered it off and back and and still retained the preset station until I turned it off and then came back several hours only to find I had to reprogram the stations again into memory. What maintains the memory and can this be replaced by me a non tech. Receiver is not under any warranty. What is the part and cost. I googled this and it seems to be a problem of the VSX-108.
The problem is IC 701. I looked it up as far as pricing and it costs around 78 dollars. I am not planning on replacing it as it is not worth it.

If you turn it off MANUALLY the power is physically cut from the mainboard where the memory is stored and it is lost. If you use the remote it puts the unit into a standby mode which retains the memory.

I have the remote, and it does not put the receiver into stand-by.
I do not believe it ever did. Is there a battery on the main board that needs to be replaced?
The above solution is incorrect. The remote standby mode is only for "other equipments". The vsx-108 does not have a standby mode. The operating instructions manual seys that the unit should remember settings when the power is off for several weeks. The unit must have a source of "keep alive" power for the memory circuits. This will be either a capacitor (most likely) or a battery. As I have not found a battery in "easter egging" the units guts I am assuming it"s a capacitor. I need a circuit diagram and component layout to find which cap to test.
