I have a Lionel Mikado cab number 1210 with no sound. The boards have been tested and all are good. The engine runs just fine so I'm at a loss at the moment.

Need more information. 6- number, running conventional or command, have you tried the volume controls both on the engine tender and via Cab1 or 2 (if running command). All sounds?
Bad speaker?
Check to make sure the opto devices on the drawbar line up. I am pretty sure the receiver and motor driver is in the engine and sound boards in the tender. The serial data is transmitted using light through the drawbar. If the rear coupler also doesn't respond that also indicates an opto problem.

Well if there is no drawbar comm, then the tender sounds would come on with track power...as if the engine were in conventional. Curious to know how the sound board and power supply were tested.

me too!

The 6-number is 6-18080. I've also tested the pot, speaker, soundboard, powerboard.

That comes up as a TMCC Mikado.
How exactly are you testing these components?
Can you fire the rear coupler?
If coupler fires, press whistle one time and keep pushing number 1 on the key pad. Do you have another tender to put behind the loco? Chuck is correct on the IR comm. again, try to fire the coupler to establish if you have comm.
I would like to hear more on how you tested everything.

I've checked the alinement of the IR and they appear to be lined up. I don't have another tender to put behind it as the moment. I tried firing the coupler and it doesn't fire.

tried it with another speaker no difference.

The only way I had open to me was to replace them with known good boards.

Marty,
The coupler does fire. I can operate the loco forward and reverse with my cab II remote. I appreciate the advise that you and the others on the forum have given me.

Where did you get the "known good boards"? If you don't have another tender, how can you be sure they're good boards?

Got the boards from Lionel so and I hate to say it I assumed they are good. The loco runs in both conventional and Legacy/TMCC, the coupler fires but no sound.
If the coupler fire and the boards are good, I'm at a loss. I think your assumption that the boards are good may be in error. Did you replace the AD20A board, it's the only thing left in there.
Did we ever establish that this is a Legacy engine? The number given shows up as a TMCC engine.

The box art shows "Odyssey System, 6-18080. Trainmaster command equipped. Pittman motor with Odyssey system. I realized my assumption that the factory boards were good was going out on a limb. My test jig is dated it came from training at Lionel over 5 years ago so I don't have a updated means to test the boards. No I haven't changed out the AD20A board.

Then you might want to edit your subject title, since there is no "Legacy" involved.

Thanks I already have.
The boards in that locomotive are more than 5 years old, so if you have the means to test RailSounds audio and power boards, they should work fine in a five year old test rig. I test them on a home built rig with a diesel motherboard wired to all the stuff I need to test boards, it's a lot older than five years.
John, I see many power boards crap out. The RS power board is the same with TMCC and modular board Legacy.
While it may be a long-shot in this case, let me give you some information on some Railsounds fixes I've been successful at lately.
1st victim was a 2005-era TMCC Mohawk (38053(?)) that stopped all sounds suddenly. I ultimately traced the culprit to the Railsounds "sound"board (the one with the two square sound chips). This was done with the help of Marty and GRJ to name names.... Anyway, I took a soldering pencil and re-heated the solder joints where the main board connector is attached to the sound board. While there wasn't any visual clue as to a problem, that re-soldering of the 20 (?) pins brought my Railsounds operation back to life.
Case #2 involves my 2011 era #34635 AT&SF F3 diesel set. This unit started intermittently losing the prime mover sounds while running; it ultimately lost all prime mover sounds + Towercom & Crewtalk announcements. Oddly (to me.....) the horn and bell still worked despite this. Looking at the Railsounds board, I noted the "wave solder" that attached the board components to the main disconnect looked milky with lots of tiny residue particles around the pins as if too much flux had been used and not cleaned off satisfactorily. I got out the trusty soldering pencil and re-heated all the pin connections and voila, all the sounds were restored.
It may be worth a try in your case as well.

Me too, I hope I didn't give the impression that I thought the board was good! 
I was just talking about testing capability.
I had the same problem on a similar locomotive. A simple reset cured my sound issue. Good luck.

I have zero info on this engine what steps did you do?

I'll give that a shot, thanks
Here's the parts listing for the locomotive.

If you have an AD20A you have TMCC. Are you a Lionel tech? The test fixture from years back is still good to test Legacy modular boards.
Yes, I am a Lionel Tech. Your right on target on the test rig. I tried it and the power board was bad. However when I place the boards back onto the motherboard the problem is still there. I verified that the IR sensors were aligned so I'm guessing the pot is the problem at this point.
