I originally posted this on the back of a long PL47 thread before I realised it was in the commercial sellers spot and my be frowned upon posting there, so I moved it……………
Does anybody know where to get replacement parts from, particularly new glass lens and maybe aux board?
I purchased and received a faulty unit recently (I was aware), which had 1 faulty LED plus intermittent aux LED’sand I proceeded to gain access through the front; the press fit retaining ring was relatively easy to remove, but despite my best efforts I managed to crack the lens :person_facepalming:
It may be interesting to note what I found inside:
- Initial view I saw the intermittently faulty AUX board looked like it had been run over; you can see in the image below it is cracked in several places and one of the cyan LED’s has completely lost its dome/gel (whatever it’s called), the one near the ‘fireflies’ printing. The faulty LED is top right in this image and closer inspection with a high powered magnifier noted evidence of the right hand bond wire overheating and bubbling the gel, presumably disconnecting and causing the failure - I have some SST-20’s on the way from BSM so should be golden :sunglasses:
- Upon removing the aux board and connecting to PSU, nothing would work except the LVP red LED’s, though if I flexed the board slightly in a certain way, the blue LED’s would light. I suspected a dry joint or a broken track, but couldn’t find either.
- After much scouring (things are really tiny on this board), I found the broken track, apologies for the poor photograph through cheapo 60x magnifier:
I managed to scrape a little solder mask and bridge the broken track with solder - not sure how robust it will be, but jeez it’s hard working on such small area, through a magnifying loupe.
- Next was the MCPCB to take out; turned out to be a reasonably substantial item. Unfortunately going to the bother of lump of copper MCPCB is a little pointless if you’re going to leave huge burrs that prevent it sitting flat, even if it were able to sit flat you could strike matches on the rough mating face and even then a total absence of any heatsink paste, at all:
Not pictured is the front of the MCPCB, bubbled in places presumably due to heat. I hope this is just solder mask and nothing terminal.
Sorry for the diatribe, but there doesn’t seem to be much in the way if internal shots of this torch and thought the pics may be of interest.
Hopefully I can get this running again; may need a new aux board and just got to try and source a new lens.
