Hi. I had the same problem, and changing the SS14 diode solved it, fyi.

Most likely the device has been incorrectly powered. The most easy way to check this is the following:

- unscrew the 4 screws on the RC-3 bottom
- slide the board out from the connectors holes
- gently detach all the connectors and wires coming to the board
- locate the schottky diode (SS14) close to the power input connector
- check if the diode is short
- replace the diode if it is
- if this does not solve the problem probably also the capacitors in the power section are shorted.

Boss rc 3

It seems that when you engage the recording mode, the RC 3 draws too much power and resets itself. Does it work on battery power? If so, then I'd check the power connector for good fit and for corrosion, and I'd check the adapter for proper voltage, polarity and current. Do you have a "PSA series" AC adapter? If not, then check the fine print on the adapter you have for Output, and make sure it's 9V and also that it says 100mA or higher. The Boss PSA can output 500mA and can usually drive 5-6 pedals with the right breakout cable. And I suppose you already have this, but just in case you want to RTFM: Boss RC-3 Manual.pdf 8-)

The Auto on my Boss RC2 sometimes doesn't seem to pick up a signal and engage. It is plugged into a multi- socket adapter and I do not have the amp turned up too loud as the room is tiny. I thought it was...

Sometimes, with BOSS pedals, the battery must be disconnected before using another power source. I ran into the same problem with my DS-1 distortion. If it's not that, then check the power rating of the power adapter. It should read, for the output, exactly 9V DC. If it doesn't, then you have to get a power adapter that has that same rating. Boss pedals will not use anything other than 9V DC (I know, I've tried).

Hope that helps!

Kyocera mita 5035 code 6400 c

Zero-crossing signal problem

• The main PCB does not detect the zero-crossing signal (Z CROSS SIG) for the time specified below.


Causes


Poor contact in the connector terminals. - Check the connection of connectors YC1-3 on the main PCB and YC2-6 on the power source PCB, and the continuity across the connector terminals. Repair or replace if necessary.


Defective power source PCB. - Check if the zero-crossing signal is output from YC2-6 on the power source PCB. If not, replace the power source PCB.


Defective main PCB. - Replace the main PCB if C6400 is detected while YC2-6 on the power source PCB outputs the zero-crossing signal.

My Boss RC-50 has stopped working. I used the power chord for my RC 50 in my Boss OC 3 pedal and then tried using the chord in my RC 50 again and it won't work. It won't even work with other power...

CHeck the voltage out of the adapter. It should be around 9 to 11 volts. If it is not, it is possible that the OC3 has reversed polarity AND a protector that put a short on an incorrect supply. If so, it could have damaged the RC50 adapter. If the RC50 adapter is putting out correct voltage, then I suspect the inout connector on the RC50 may be damaged or not quite seated. Visually inspect the connector first.

Model HSB03 stopped working after power outage. Is still like new would like to keep ....any suggestions?

HI. What generally happens during a power outage, will be a serious surge. The surge will, essentially, destroy the Main PCB. Without proper PCB function, the unit will not operate. All power is controlled by the main PCB. It routes power to the compressor and fans, as well. You can, visibly, inspect the affected part by pulling the access panel on the rear side of the unit. It will be mounted on a bracket, near the compressor assembly, or just in the middle section of the rear side of your unit. Inspect the Circuits and relays that are mounted on the PCB. If burn marks are present, or a brownish discoloration is sited on the circuit board, simply replace the PCB.

NOTE_ PCB location may vary in your model Generally, they are located just behind a access panel, on the rear side of the unit. Some may be mounted in close proximity of the compressor platform.

Hi. Due to the fact that the fans are not operational, this will confirm that the Main PCB has failed. This is the main power control board. It must be replaced, asap. The general location of this affected board will be just behind an access panel, near the compressor unit, or on the backside, mounted in the middle section of the unit.

Once the Main PCB board is replaced, the unit will return to its normal operating status.
