troubleshooting a non-functional Smirnoff lightning lamp
Hi, I just acquired one of the Smirnoff lightning lamps from a local
sale. Unfortunately, it worked for an hour and then stopped and hasn't worked since. I took off the bottom cover which revealed a small flyback, what looks like a couple of mosfets, a driver transformer or two, and maybe a timer. Specifically, it is called the "Smirnoff Tempest Bar Glorifier" made in Korea for Neu Solutions. Unfortunately, they haven't been made in nearly 20 years. Does anyone know of a service manual and/or schematic for this device? I'm having no luck googling for it. Fortunately, I am going to be able to borrow a working unit. If anyone wants to roll up their sleeves and help me troubleshoot using the working one as a template, please share. I'd be more than willing to post pictures of the circuit board, components, etc. I think the first thing I will do with the working unit is take resistance readings of all components while off and discharged. Then, while on, take voltage readings of the same. I don't have enough experience to try reverse engineering a schematic which is why it would be oh so helpful to find one from the manufacturer. Any information provided would be welcome. I'd really like to get my broken one back in working order again! Tips, measurements, etc welcome. Thanks in advance, Tempy |

I would start over with an entirely new power-supply, if you are so-inclined. You will get better reliability, at least, than dealing with 20-30 year old components.

.... this group exists to teach people the hard way of doing things - rather than the correct, effective or efficient way.
Anon. a) Verify the flyback as correct. This can be done cold with simple resistance readings. b) Verify the power-transformer. This can also be done cold with simple resistance readings. c) Build a new power-supply - looks like about US$10 worth, including the heat-sink. Less transformers, of course, if needed. d) Even both transformers should be able to be had for less than US$20. If you start screwing around with the borrowed unit, you may have two dead devices on your hands. By your own admission, you are not a highly experienced expert in these things, so I am suggesting you err on the side of caution. Peter Wieck Melrose Park, PA |

By the way, one thing I don't like seeing is no power transformer. I believe this was line powered. Ouch! Line-powered to the flyback - which isolates as well. Peter Wieck Melrose Park, PA |

The kind soul who loaned it said to be prepared to shell out $50 if I end up "breaking it". Since they seem to go for well over that online, this isn't an end all, but I still want to be as careful as possible. I think I'm going to start with my broken one by taking pictures of the components side and then the board side. I may try superimposing them together in Photoshop. It might make not only troubleshooting easier, but I *may* be able to draw a schematic later. Also, I shouldn't have to disassemble his at all, just readings from the underside once I know what is what. At some point, I will post these images on imgur. |
