    Emerson E320VT power supply problem

    I just can not seem to get away from defective power supplies in Emerson/Funai branded Tvs. Anyone have a schematic or know the value of Q501 and R501 in the power supply. The board is a A21F1MPW. Thanks very much.

    Emerson E320VT is that the correct brand and model?
    E320VT is VIZIO: http://www.walmart.com/ip/Vizio-E320...ished/21777180

      Re: Emerson E320VT power supply problem

      I posted the wrong Model No it is an Emerson and the correct model number is LE320EM3. How can I change the thread title to the correct Model? I do have a vizio with the E320VT model number I am working on also. I typed the wrong model number in the header. Sorry.

          David, this is Larrygad7, the value for the resistor is 47ohms 1watt 5% that is
          R501 the Q501 is K3498. I hope this helps. Larry

              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...

              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...

              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...

              What capacitor should I purchase for Power Supply of obsolete game consoles?
              by chth96
              hello.

              I have Sega Saturn and 5 years ago, I recapped all of capacitor in the Power supply, Because At that time, It frequently freezed black screen after SEGA logo displayed.

              It hardly ever freezed after I finished to recap all of caps in the power supply.

              But Yesterday, It did not show any screen at all and its green power LED constantly blinked.

              To my surprise I found that all of two NXH 10v 2200uf capacitors in the secondary area of Power supply have been bulged and It measured 57 mF and 75 mF capacitance.

              It seems that quality...
