Re: 4BX prob.
I bought the 4BX when it was new, to replace the Original 3bx. I experienced the Exact same problems.
To make a Very Long story short: The 4BX must, Must, MUST be powered from a Very Good Surge (Voltage) Protector!!!!!
I'm talking about a Surge Protector that can Clamp the line voltage to Under 220V, within Mili-seconds!!!!!!
Reason: Power line trancient spikes come into the 4BX & lock up most (all?) the logic ckts needed to operate the 4BX.
Unplug the 4BX for several (3-4) days & let the residual voltage that controls the 4BX IC's, die off. The 4BX will work normally again........until the next AC voltage spike locks up the IC's again.
Put the 4BX on a Very Good ($100, 1988 dollars) Surge Suppressor & your 4BX will love you forever.

NO Battery

No battery in my 4BX. I checked that Years ago. The memory settings are stored digitally.Just a wild guess... how did this unit "remember" settings? Is there a back-up battery that could have died?

@MLStrand
CFLs and Plasma TV with mess with the remote signals. There is a physical reason why turning off and letting a product sit will "fix" it. The 4bx does have a ZNR on the input, but it's only for normal mode and not common mode signals since there is no 3rd prong.
@dangus
The 4bx is quite unusual, the settings are only remembered when it's plugged in. Once you remove power, the settings are gone. It was designed like this from day 1. Only operating the front panel power switches will the settings be remembered.
@Anybody
Would any 4bx owners want to own a modification of the 4bx which would remember settings by allowing a switched outlet to turn on and off the 4bx such that the settings could be remembered? What features, hypothetically, would you like it to have?
For instance, some digital functions include: 1) a pulse on power up 2) a pulse on power down; 3) State: On/Off/Mute, possibly Bypass 4) Pulse to power up and 5) Pulse to power down and 6) Rising edge to power up, Falling edge to Power down
How should the signals be implemented? Optically isolated?
Should the time delay between on and mute be adjustable? What range? Should you allow power-up in mute mode?
Most people, I think would be satisfied with just a switched outlet for control. I need the pulse when turned off and a pulse when turned on.
This is just an idea. How to handle 240/120 is a complication. Any discussions welcomed.
My system uses an Audio Timer and does not have an IR enabled receiver. So, pretty much from day 1, I modified the 4bx so that an optically isolated pulse between 3 and 30 V could turn off the 4bx. An optically generated On state was also generated.
This allowed my timer to turn off the 4bx and could be accomplished with a "switched outlet control". The "power up" signal told the timer to power up the entire audio system from the 4bx remote.
