    Vizio E322AR power supply

    This is the small xfmr T501 from the power supply AIVP-0089 . I can't find a schematic online and can't reference the part # for the xfmr either. It reads shorted on the primary side, I assume thats normal . The secondary reads open , I assume thats bad. When in circuit I read 168vdc on primary and no volts on secondary. Can someone help identify this xfmr?

      Re: Vizio E322AR power supply

      Update, After spending 5 hours researching with no results I ordered a lot of 5 bad power supplies from ebay. One is the same as this one and is described as "makes tv flicker". Could be the main board was bad. Either way I think I can make a one good board out of these two and have 4 more boards to play with.

          There seem to be a number of "cap Kits" available for this board - that in itself suggests the
          original caps are poor and fail regularly. Whilst I dont suggest buying a cap kit off ebay
          (except from certain sources) you should consider changing all caps on the board except the BIG cap, or at least the 12 or so caps in the kits
          Please upload pictures using attachment function when ask for help on the repair

                  Update, One of the 5 "bad" power supplies I ordered worked. The tv powered up and works fine but there is a small crack in the bottom right corner and a blank spot. Buyer beware, the guy I got it from said it was in perfect condition. I handled it with care so I think he was BSing me to get it sold or he cracked it when he was trying to fix it and didn't realize it.O well, I only gave him $20 for it and I learned to check for cracks with a flashlight from now on. I'll just put a plant or something there to block the spot a keep my eyes open for a compatible screen .

                      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.

                      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...

                      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...

                      Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
                      by JimBanville
                      The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
                      Opened it up and discovered the power supply is making a faint clicking or ticking sound.
                      I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
                      I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...
