I am by no means and EE but my PP205 had a display that went in and out and had funny characters showing. I called support and they had me take the cover off and make sure the display connection we tight/secure. It was loose so I secured it and now my display is working fine. I don't know if this will help but, you should call support. Good luck.

Any success in figuring out the problem? Of course it is the weekend so I suppose tech support isn't the easiest to get a hold of. Hopefully it is something very simple as suggested by NRM above.

No luck. I had already tried the things mentioned with out success. I spoke with Ray and he decided the machine needs to be sent back. I hate this as I have to go borrow a tig welder to do some repair and modification work to my dragster. What I dont really understand is it was working flawlessly 6-7 weeks ago and had been sitting in my shop on the cart all rolled up, unplugged nice and tidy in its spot. As soon as I find out what happened Ill let everyone know.

I was hoping to have all this behind me by now, just got the machine back Tuesday, box looked alittle rough opened the box UPS has broke the front bezel and pushed back the connections for the ground and torch. Checked to see if anything was grounded out, didnt see anything pulled the panel back out. Put power to the machine, powered up fine, ran for about 30-45 seconds then a loud pop, trips the breaker in the breaker box. Called Ray he instructed me to pull the cover and check the nylon spacers that hold the heat sinks in place all are in place and make sure nothing is shorted or broken. Cannot see any shorts or burnt circuitry or burnt electrical components or burnt smell nothing broken. He said put power back on the machine, powers up fine display OK seems to be working, BUT has no output only the HF . Will not pull any arc when in stick function either. I have become very frustrated at this point Ive been dealing with trying to get my welder back in action for almost 12 wks now. I really really need to get this worked out Im getting really backed up with personal projects along with customer work.
