Eotech 512 problems

[Force]

I've had an Eotech 512 A65 rev F on my patrol carbine for around 6 months.
In those 6 months it has worked flawlessly.
Last night I turned the Eotech on, and instead of the nice crisp circle and dot,
the reticle was kind of pixelated. Instead of the single row of dots that make up the circle, it was now about 4-5 dots wide. I tried turning it on/off a few times, brightness all the way up/down, still the same. Changed to brand new Alkaline batteries, no luck.

For some stupid reason our work computers are blocking the Eotech web site today, so I can't research it. Will try from home tonight.

Has anyone heard of, or experienced a reticle spread problem with an Eotech like this before?

Update: I checked out my Eotech again last night. It seems to be working perfect now.
Don't know what the problem was, maybe my eyes. It's working fine now.
