    Kenwood R-42L / X-42L problems

    Hello

    I have acquired a Kenwood R-42L tuner / amplifier and associated cassette deck X-42L.

    The person I got it from assures me it was temperamental but working when they had but now it is totally dead ... there are no lights when plug in and no fiddling with any buttons makes any difference.

    I have of course checked the fuse (!).

    I have it set up in the same way at this:


    Does anyone have an magical ideas that could help me to sort it out?

    Many thanks,
    Danny

    open it?

    Trace the circuit from AC input cord all along the path. If it's difficult to follow, see if there's a separate power supply board and check whether there is any output from that.

    If I had to guess, since there aren't even any lights (though it could have had more than one failure by now?), maybe burnt rectifier diodes but that's a random wildshot guess.

    Providing good top-down pictures of the boards, particularly the power section, might help.

      Kenwood KR-6030 vintage stereo ,Old Man Trying to Save a Buck
      by DrDos
      Hello all. I'll try to keep this short. I have no knowledge of electronics. I can use a multimeter and am familiar with caps to some extent. I bought a Kenwood KR-6030 vintage stereo. It need work and so I thought I would recap the thing since I get power to the on switch but nothing else is working. No lights, no sound and so forth. I went to Mouser to order caps and I find I am way over my head. I not only do not know the type of capacitors I need but Mouser and digikey do not accept Kenwood part numbers. I have the info such as 220uF 63v and such but no place to put it. I could buy a recap...

      USB problems?
      by Hondaman
      Recently I discovered my SSD died (OCZ/Toshiba 240 GB). It was in a USB enclosure, attached to the Linksys WRT-AC1200 router. Since then I removed the USB enclosure and attached it to my Win7 PC (AMD 8150 CPU, 970 chipset, 64 GB RAM). I also gathered one or two other USB enclosures to figure out what is going on.

      (I suspect that I lost quite a few MP3 and FLAC files I recently ripped from my audio CDs, I think I lost very little un-replaceable stuff.)

      I think it is IMPOSSIBLE for Win7 to have any problems with a USB enclosure as long as Win7 knows how to speak to the...

      Lenovo 11e problems (any sata hdds are not recognized, sleep battery drain)
      by clabr
      Need help to solve some problems with this laptop.

      After working in bed with it one night and heating up too much (probably the cause of this problems) the sata HDD OS windows froze
      After restart the original Sata HDD was not recognized anymore (but works fine in other laptops or PCs)

      Tried connecting other good Sata 2.5 HDDs but not one is working in this laptop anymore (not the original nor others)

      Before this had happened I observed some other problems:
      When I tried replacing original mecanical HDD with a SSD HDD could not get them...

      by jean luc ferre
      Hello,
      First on my laptop i had a motherboard with a pentium 6100 processor. Installing w11 i was blocked on the 23h2 version...impossibility to upgrade toward 24h2 because the SSE4.2 functionnality of the cpu was missing. About displaying and screen looking all was perfect.
      I changed of motherboard with an intel I3 processor...and now i don't find the previous aspects of the displaying.
      Now i have a veiled screen and pixels are missing though the graphics parameters have not changed.
      Desinstalling and reloading the drivers in the same time on the graphic card (intel hd...
