Do you have original smps energizing power supply what uptone was selling with lps-1? Do you try that?

Also is your 12v power supply following this criterias?

I've tryed the original smps but with the same result,using a hdplex 400 w supply otherwise.

When this happening do you energizing same divice with lps-1? ( have plug in device on lps-1 output?). If yes just unplug wire from lps-1 output and try repoweing lps-1.If your problem will repeat contact the seller to resolve the problem  or Uptone audio via contact page on their site.

I have a five year old LPS-1 which was showing some erratic behaviour. Looked at the board inside and the two small upright supercaps had leaked something. Cleaned the substance, changed them and now it functions perfectly.
