My omega likes to occasionally just cut out. Usually when I'm playing with the disc or sensitivity knob, the screen will just blank out and start back up, occasionally I'll have to turn the machine off and back on. It's not very often, but damn it's annoying when it happens and I dont think it should unless there is something loose. Thinking of sending her in for warranty work once the snow flies. I've also got a little problem of one corner of the screen starting to pry up a bit .
I bought my Omega second hand, the seller had sent it to First Texas and it had been repaired, he sent me the shop repair form with the detector which stated "Replaced and adjusted discrimination component and Reprogrammed Unit"
When I got the machine it worked as designed, however after a few trips to the beach, it had started giving intermittent problems.
1. Would not go into the ground grab mode. Just nothing, this was at a rate of about 50% of the time.
2. Same issue with pinpoint.
3. On occasion the above issues would be accompanied by a screen blanking.
I found turning on and off, made it work for a while.
After reading your post, and having basically the same intermittent issues with mine, I realized that it might be a cold soldered joint, if you don't know this term it amounts to a less than professional soldering attempt, resulting in a joint that is not fully bonded, hence often causing intermittent issues (hobby was electronics for a few years).
So with no warranty I opened the case up. Simple to do, but I was gentle.
I inspected all soldering under magnification and bright light. Saw nothing wrong but, I noticed a 2" piece of electricians tape on the backside of the printed circuit board, and it did not look to have been applied during manufacturing.
So I pealed it off, and guess what I found, uncleaned solder joints from I assume, the replaced component during its repair, brown resin which can be somewhat conductive. There were no cold soldered joints but since the pins were close together like they have to be, what I found after I cleaned with denatured alcohol was bridge of resin between two adjacent pins in the row.
After scratching very lightly with an exacto knife to break the bridge ,then some more cleaning with alcohol and a toothbrush I buttoned her back up.
Results, I have working Omega 8000, goes into ground balance, pinpoint and so far works just fine after several on and off cycles.
After a little time l will see if the cleaning job is all that was needed, but I now believe it to be repaired.
Disclaimer: Stating the obvious; If you decide to open yours up, your detector SHOULD NOT be in warranty. I am NOT suggesting you do this, in fact you probably shouldn't unless you understand what I am talking about, and have the know how. Should you trash your detector, don't blame me.
