An idle thought. Are you sure the cables are all seated properly into the xvrtr? It is not difficult to think you have the TMP cables seated only to find that all you've done is force the center contact in the jack backwards ... so that it becomes intermittent or open. Easy to spot and fix ... the little plastic surround for the center contact will be pushed backwards at a funky angle.
I learned to always leave the cover off the xvrtr when attaching cables. A couple of them (don't recall which ones specifically) are prone to this problem. Don't ask me how I know this ;) Grant NQ5T Sent from my iPhone > On Jul 24, 2016, at 9:25 AM, mike <[email protected]> wrote: > > Apparently it is an intermittent problem.
