Dear earthkmtech

i did all those of course and still could not figure it out. I don't post just to feel good. I'm stuck. I have replaced all boards, including power supply and it works for a bit then shuts down again!

We can't upgrade it now, must fix.

help if you wan but I'm not rude it just takes me 20 to 30 minutes to get somewhere where I can reliably check the posts, thus if someone posts things that don't help the fix then it is frustrating!
