Problem CB200 REX 7 assist and RSAT2

Hello everybody. Last Sunday something unpredictable and meaningless happened. I was in flight with my extra 300 104 'with primary receiver CB 200 Rex 7 Assist with gyro not activated and as secondary Rsat 2 with 2 Jeti 3100 mah batteries. All servos are 7.4 volt Savox SV 1272 SG (I think I have made 70/80 flights without problems) and suddenly the right elevator floor stops working. I managed to land without any problems and I wondered if I had the batteries a little down even though I had charged them the same morning and it was the first flight of the day. I turn off the engine and begin to check what may have happened and the elevator floor sometimes moves and sometimes doesn't move. I turn everything off to check the plugs but everything is ok the servos have no smell and everything seems ok. I go to turn on the system again and nothing turns on anymore as if everything was dead and I hadn't done anything. I decide to go home and calmly start checking. Arrived at home I assemble the model I connect the batteries I turn on the DS12 transmitter I turn on the RCswitch the green LED turns on but the model shows no signs of life, I check with the tester if the CB 200 is powered and I find 7.9 volts at the output, check the voltage of the batteries and both give me 7.9 volts, I check the voltage that reaches the receivers with the tester and is 7.9 one and 7.92 the other. The telemetry works but no servos move and I see in the telemetry VOLT RX 1 6.91 volts and VOLT RX 2 7.91 volts. Why is there a volt of difference? . After a bit of calm I begin to remove the primary RX and suddenly everything turns on the servos work, I reconnect it and nothing works anymore. I turn off everything I remove the primary RX, I make a new model nothing to do it does not connect anymore, I take the other transmitter the DC24 I make a new model but it does not work anymore, I tried to do an update with Jeti Studio but it seems dead too if the power comes in. I tried to change the port with Device Explorer but nothing is not working. I thought dead for dead I open it, I struggled a bit because it closed very well, after having opened it inside there is no smell the tracks seem ok but it doesn't work. I take another new REx7 Assist from the closet and connect it to the CB200 as the primary RX and everything seems to work, but I have many doubts why an RX stops working so suddenly? I take the TX I see that everything works and I enter the Wireless Trainer, I deactivate the secondary REX and everything works, I deactivate the primary REX and nothing new works anymore and from that moment the RSAT2 no longer connects, and powered I see the telemetry but not makes nothing work. Now is the time to ask for help because I no longer understand anything.
Thanks for your help

the text you posted in post #1 is hard to follow and read as you did not use and linebreaks and paragraphs

if you still can edit it, try to format it a bit using your ENTER.key
group the things you did a bit to make it easier to read

... then post your logfile(s) too pls

Ahh ok !!

now i'm in contact with Jeti and i wait answere from him

Hi,

maybe there is a problem with one of the receivers binding to the transmitter: The transmitter does not detect two working receivers and therefore does not activate the model - with the result, that nothing is working.

Is it possible for you to use two other receivers with other cables to connect them to the CB? If everything is ok then, you know that one of the receivers is damaged.

Kind regards,
Kai
