When I first turn it on then I select 222, it will play then select 111, it will play then 233, will not play scans twice then stops, then 100 it will play. If I repeat the same selections. 222 will not play, scans twice then stops. 111 plays 233 does not 100 plays. I hope this is helpful. Thx

I have not had a chance to look at the TMU wiring. I didn't mention that when I put a battery to the RCA jack that all the selections play. Does that change your answer? Thx

I do have the manuals. I will look at that. Thank You.

I hope someone can help. The LS325 will play any 2XX selection once, when it is first turned on. No 2XX selections after that. All the 1XX selections play fine.
