    Need help for broken Transporter

    Hi all

    I am a long standing Transporter owner, but unfortunately my unit is no longer functional.

    What happened:

    First the screen stopped working, however I was still able to control the player through the web interface / iPeng and sound was fine. I tried restarting the unit by holding the power button - the unit clicked and restarted but the screen was still not working.

    I then unplugged the unit, opened it and checked for a loose connection to the screen. I plugged it back in and it no longer started at all. No click sound when starting up, no sign of ethernet connection on my router, although a red LED was flashing on the board (see picture below showing the light above the WLAN card).

    What I have tried:

    1. I removed the WLAN card as suggested in previous posts but still no start up and still the flashing red light
    2. It seemed to me the secondary beige board between the main board and the display was related to turning the unit on/off. I unplugged the cable between this board and the main board, turned the unit on and the red light did not flash. As such, I believe the secondary board is allowing power to pass to the main board.

    Any suggestions? Are Logitech still supporting these units? Even if they do, I'm based in Hong Kong which complicates things somewhat.

    Thanks

    Luke

    Did you check the fuse?

    Thanks Peiter

    I checked the fuse visually and it looks OK. The red light when plugging into the power seems to indicate there is some current passing through it.

    I can try removing it and seeing if the red light still comes on or not. On the board it says 250V 500mA slow, which I assume is sufficient specs to replace it if needed.

    The red LED is situated next to the IC that looks like it might be connected to the IR Output. Have you had anything connected to the IR In or Out jacks (recently)?

    Hi Gandhi

    No, I don't think I've ever used the IR port...

    I seem to recall that the beige board creates the high voltage for the display and that it is situated far away from the DAC circuitry to minimize interference. The internal PSU must then be powering the beige board, which also is how I interpret the cabling in the picture.

    The blinking LED might be indicating that the PSU senses that it is shorted, turns itself off (LED off) and then tries again (LED on). If the blinking stops when you remove the beige board, it might indicate that the short circuit is somewhere in the beige board.

    Is your Transporter capable of playing audio without the beige board (but with no display)?

    Oh, and did I say "might"? ;-)

    I think that beige board is a power supply for the VFD display (but I could be wrong).

    It is a bit hard to give advice on such issues especially since there is no technical documentation available. But a good start is to measure the different power rails.
    For sure there is 5 volts and two rails for the analog (+ and - something like 12 or 15 volts).

    *Exactly* the same for me

    Hi,

    Exactly the same issue here!

    On Dec 31 my Transporter was playing happily all night through new year and on the wee hours I hit stop and switched my amp off. The next afternoon on 1st Jan I tried switching it on but nothing happened. No clicking noise no display not reachable over the network.

    I tried all known resets/xilinx etc..also with the wi/fi card ejected...let it off the power grid overnight nothing seems to work since it does not power up.

    The fuse is OK.

    Everything points to hardware failure in some very early link of the chain (although I'm not an engineer)

    I visually inspected the pcbs but all "seems" ok...apart from that *$#^@! diode led that keeps binking red. Anyone knows what this is? An error code?


    Does any fellow squeezebox owner with a technical background have a suggestion?


    I will give another more thorough visual inspection on the parts with a magnifying glass and take pics during the weekend.


    I wish to all a happy 2014! (although it started on the wrong foot over here)

    I just had the same issue start with my Transporter. Were there any solutions?

    Hello there.

    It's been a year since mine died like I described above but life got in the way and I never found time to deal with it. (have put a spare SB3 as a "temporary" replacement)

    What I can suggest though is to visually inspect the small pcb feeding the display since upon **closer** inspection I remember I saw what appeared to me as burning discolourisation..it was a resistor or a capacitor if memory serves..but the burning was more evident on the pcb beneath the component. I always "planned" to look deeper into this but never got around to I admit.

    If your TP shows similar findings then I would feel pretty confident that we have isolated the guilty party.

    My second guess would be one of the power supply relays on the upper left being stuck or fried.

    If you can report back I would appreciate it and I'm sure other TP owners in the future as well, since there seems to be a pattern here that maybe is affecting TPs as they age.

    Good Luck
