    ILO (AKAI) 32LTC32HA36 power supply MLT169B R68 value

    DOES ANYONE KNOW THE VALUE OR COLOR BANDS OF R68? MLT169B REV 1.1 2006.05.13 (between heat sink 1 and T3 x-former)
    I have already replaced 9 caps on the P.S. and noticed the PCB was dark under R12,R13 on the bottom side. I found C18 open and I cannot read the color bands on R68(possible heat damage). I am not sure if D14(HER207) or R68 are bad. Thank you

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Assuming...

      Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
      by sam_sam_sam
      I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

      One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

      700mv ripple on Akai Sampler linear supply
      by sumilumi
      Hi fellow troubleshooters. This is my first post on badcaps. I've recently setup an electronics workbench. i'm also building a studio with old equipment bought faulty at low cost.
      I've been into electronics since the mid 80's and particularly in the last few years though only getting hands on with repairs now. My knowledge gaps are significant so I'll be posting here to seek guidance advice and general practical applied learning.

      On my bench today is an old ca. 1993-95 Akai hardware sampler. This runs on both a linear and Smps supply. Both are getting on in age and ripple...

      Modification to a ZD-987 desoldering/soldering station using a external switching power supply
      by sam_sam_sam
      I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

      I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

      Russound CA4 Power Supply Repair
      by CMCM
      Hello Everybody,

      Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)

      Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).

      The outputs marked 12v and 20v are all measuring only 1v.

      The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.

      The capacitors physically look clean (no bludgesor leaks) and...
