    I, too, am a successful power supply replacer. Likewise, figuring out how to get inside was the hard part for me. (4 screws on each side of the unit, with a 1/16th hex mini-screwdriver.) The PSU comes out with, what my kit shows to be a "*T7" mini-screwdriver. Replacing the PSU, itself, couldn't have been easier.

    This thread represents everything great about community forums. I was about to take my 7+ year old transporter to the tip on its apparent death, but fortunately decided to look here first. I'm in the UK so yesterday I ordered a PSU from Rapid Electronics as recommended and it arrived today (£8.47 + VAT - bargain). Not only did it revive the display, it also seemed to magically repair the DAC which had packed up about a year ago. As I have a Lyngdorf digital amp as well as a Quad 66, I was able to swap my "squeezeboxes" around previously so the loss of the DAC wasn't the end of the world. But at least I can now use them as preferred.

    Absolutely over the moon that the Transporter is now as good as new for about £10. It was very straight forward until I stupidly managed to knock a couple of capacitors off the display PCB. it took me over an hour to replace them after watching some YouTube videos to make sure I got it right - quite a fiddle!

    While I was on the forum I had a look at LMS stuff and decided to update to 7.9 from 7.5. My NAS runs Windows Home Server which I've previously updated and had fortunately made notes the last time I installed what was then a Squeezebox Server update.
    And to think I was seriously thinking I would have to invest in new players/servers etc and start again. I was looking at what seem to be called "network music players" when I came across the Linn Klimax DS for a staggering £15,800 here in the UK! it doesn't seem to do very much the Transporter doesn't do, but of course it has the fancy power supply (probably costs more the £10!) ultra-low jitter master clock and is made from a single billet of aluminium- but does it sound any better? Or more to the point - is it £14,500 better?

    Once again, many thanks to all the posters here.

    £14,500 would buy you a pretty nice external DAC, and still leave money for a lot of music...

    Hi all,

    I repaired a Transporter in September 2016 that had display failure as described here - displays dark but otherwise it worked as it should.
    Referring to the beginning of this thread, let me give you an advice first: remember the Transporter is only without power when you pull the mains plug! Standby means the displays and outputs are off, everything else is running just like under full power. You may have noticed that the Transporter is feeling warm at all times. So (un)plugging the flat flex between the main and front PCB is not a good idea unless you are sure that the circuitry is not powered. If the flat flex cable is at the slightest angle when you plug or unplug it, you might create a short circuit with very bad consequences. It might be a power regulator IC on the main board that blows (silently) instead of the main fuse. Rather hard to identify and to fix.

    That additional 5V power supply board is definitely the culprit in most of these Transporter display issues. It is really an odd design choice. Other Squeezebox devices are just using a 5V power regulator component on their main board and there you go. Why they took the trouble of adding a completely separate board can only be explained by the power draw that two VFDs generate. Each uses ~800mA for the heater wires permanently at 5 Volts - no joke, even if the Transporter is in standby and does not display any content, the displays and their heater wires are permanently powered, just as in every other VFD Squeezebox device. It's one of the things I criticize most about the design. The 55V high voltage that was mentioned before in this thread is not for the heater wires by the way but for the VFD grid voltage, and is indeed created locally in circuitry for each display separately on the front panel board.
    What that means is that this 5V power supply board in the Transporter is also powered at all times unless you cut the power on the primary side. On first glance I thought, that's quite a Wun Hung Low piece, not really matching the rest of the hardware quality-wise. Still, Rapid Electronics seem to be one of the better manufacturers. Customer support appears to be over-average at least, considering how forthcoming they were.
    Anyway, it appears that switch mode power supplies are just not made to last forever. I understand that many people find it too hard to identify the actual fault in the power supply and prefer to buy a new replacement. Going any further requires additional tools, and dealing with high-voltage components is just not everybody's favorite hobby either. Some might reconsider this because in most cases the repair can be done for a minimum spending. It is one or two of the electrolytic capacitors. In the Transporter I had here for repair, I replaced the two that you can see front row right:

    The third one that is missing in the picture measured okay once it was outside the circuit so I soldered it back in - just like the 4-pin connector that I desoldered no idea why.
    A good amount of heat has left its traces around ZD3, however, that part (a Zener diode) also measured good. What I think might cause the caps to fail is the proximity to this component. Electrolytic caps don't like heat pretty much because their liquid content evaporates when too much heat and resulting internal pressure is present. We are talking about a process that takes years, of course, with constant power and constant heat.
    After replacing the caps, everything was back up and working fine. I spent about 50 cents for the parts and half an hour of work.
    My recommendation is to put the caps as far away as possible from the diode, so don't shorten the legs of the new parts, instead isolate them with shrinkwrap, and bend them sideways, as far away from the board as possible, then stick them to the base housing with "hot-snot" glue or whatever you have handy. That's to avoid that any vibration causes the leads or the soldering points to get brittle and fail.
    There could be other failure reasons, of course, but I think that the caps are the prime failure point because of their unfortunate placement. I'll happily take care of Transporter repairs inside the EU which have failing displays (except Switzerland, sorry, the customs and shipping are completely over the top). I can also replace faded and burned-in VFD displays by original spare parts, using professional equipment and providing high quality work at a hobbyist price. If you want to have your original 5V board repaired, I can at least give you an assessment of the chances and expected cost.
