Is It Possible to Repair Rohde & Schwarz RT-ZP10 500MHz Passive Probes After Overvoltage?

Hi everyone, I have 3 damaged RT-ZP10 500MHz passive probes from Rohde and Schwarz. I've been in contact with a few places to repair them and they recommend dumping them and purchasing new ones. Direct replacements are about €300+, while rebranded options are about €200+. I think this is a bit of a waste, so I decided to have a look and see if anyone knows if this is a) possible and/or b) pointless? Are they really this hard to fix? As far as I know, the damage was caused by an over voltage condition. In my naivety, I'm assuming some discrete components are fried and can be replaced. I'm probably way off.

Mike,Seems to me there's a YouTube video for anything. In my story, I mention such a video for ifxing the 34401A capacitors.

I just read your article this morning. I really enjoyed it. I love the detailed schematics and photos you took for the piece. It's clear and easy to understand.
I've had a look for any such Youtube videos specific for the part and I haven't found anything yet. It will take a little longer to hunt for something similar. If there isn't a Youtube video, maybe I should make one or at least write it up. I figured there must be a reason why I can't find anything on this yet. 

Hi Mike-What are the symptoms of the failed probes?  I think you're probably correct- it is more than likely a failed discrete component.  From the picture of the probe on the R&S website it appears that the discrete components are in the end with the BNC connector on it which is more than likely potted. This makes repairs extremely difficult or impossible.My thinking is that if the BNC end is potted, save the probe tip and other accessories and toss the rest (sorry).  If it's NOT potted, give us some info about the symptoms and we will help you troubleshoot it.-Rick

Hi Rick,They don't work at all. I see nothing on the Oscilloscope. I've checked each port with a good probe.I'll try bring one home from the office and play with it over the Christmas holidays.I hope it's not potted, but if it is, I'll get the Dremel out and see how far I get.
