Raritan Dominion - Cover 01 - 1080p

In this video I repair a Raritan Dominion LX-108 IP KVM in a very professional manner using wood. It goes on for quite some time, but that’s at least more appropriate for YouTube than other platforms. No biggie, you can always skip around using the chapters. For posterity, here’s a transcript of the video in case you’d rather read than listen. But beware! It’s as transcribed by YouTube and so may include some errors and lack of punctuation (and etc). well hopefully it’s repair time today I have here a Raritan Dominion lx18 8 Port IP KVM switch which has served me well for many years now it customarily sits in a rack at an off-site Data Center and obviously … Continue reading

LeCroy WaveRunner 64Xi-A-N Oscilloscope Upgrade Attempt

Video

  By Scott • 2023-11-03 ,

I got this LeCroy WaveRunner 64Xi-A-N Oscilloscope from eBay because I needed a faster scope than my best 200Mhz Siglent model.

On eBay it looked super clean and in good cosmetic shape, and was shown and claimed to be working. When I received it, it would kinda start up, but the display was blank and overall it was unresponsive. When I went to make this video showing the investigation, it powered right up! Strange.

So I figured I’d just be replacing the RTC battery and upgrading the HDD to an SSD. Turns out it already had an SSD and a new battery. The problem was that it would reboot every time the USB ports were even slightly jostled.

After getting the motherboard out (which is standard-ish mini ITX style), it turns out that the PCB is really badly warped. That’s probably leading to cracked and/or damaged traces, possibly in internal layers. I’d wager that’s the cause of the reboots.

I posted this video more for posterity and in case anyone wanted to see an albeit slow teardown. Apologies for the rambly nature, but this really didn’t go according to plan.

Repairing a TrippLite Isobar Power Strip

TrippLite Isobar4 Repair

The Problem I purchased four TrippLite Isobar Ultra 4-Outlet Surge Protectors from eBay for about $50. They were all well-used, but purported to function. Unfortunately, two of them did not. They wouldn’t conduct any power to the receptacles, and displayed a fault LED. Hence the Video Fortunately the problems were identical for both, and very easy to fix. There are a pair of very robust and heavy inductors on the PCB that routes power inside the Isobar. They’re not mechanically fastened to the board, except by two relatively small solder joints. Either in their previous life of hard use or during shipping, they must have experienced some bashing around which caused inductors in both units to become un-moored. A bit … Continue reading
