[TenTec] Omni 6+ Opt 3 problems

[Mike Bryce]

Pete,

the first line of troubleshooting this project would be to pop the top and bottom, watch out for that speaker wire, and then one at a time pull and reset each and every one of the MTA (mass termination assemblies) ---those white connectors with the wire wires--- 

do that on each one and several times. 

there can be oxide that builds up on the pin and by exercising the connections, you'll fix a lot of problems.

I'm not saying that will smash your bugs, but it's a good place to start.

do every connection going to the logic board and the front panel.

So in looking in the manual I see that by holding in the "Lock" button for one second gives access to the menus and the clock set is in Menu 1. Sure enough I did that and the panel display  read  "Change". The next step is to hit the "Enter" button to scroll through the 13 menus. Only in my case it does not go through the menus but returns to the normal display as before engaging the "Lock' button.

The cable to the amp was tested as was the amp switching and they are good. ( The amp is a SB-200 with the soft key mod so I do not think anything was fed back into the Omni 6 to kill the keying). The keying relay K1 is triggered by Q16 (MPS6514) but the driving signal to Q16 comes from the Logic Board via connector 59. U22, pin 4 sets the driving signal to Q16. When this pin goes high it keys Q16 which engages K1. So this may be the connection related to the first problem (after the two resets) as the driving signal comes from the Logic board and it is the same board which has a problem in not being able to scroll through the menus.
