I have an Eotech 552 rev F   today when i went to shoot  turned on EO turned up the brightness inserted mag chambered a round went to take aim and the EO was off or a least not visible. Tried to get it to come back on/ turn up the brightness to no avail.

Removed the batteries and let it sit for a minute or two while i retrieved more bateries installed new batteries  first round fired EO shutt off/ not vissible again. so i just shot with irons


IIRC not long after i got mine 2~ yrs ago or so i read about people having similar issue and their was some easy fix???? But i never had a problem with mine and cant remeber what the "fix" was.

Thanks for your help

Same thing happend to mine. I had to send it in under warrenty. I believe they had to rebond the reticle to whatever generates the image. I was also having a problem with battery life was a related problem.
