    Polaroid FLM-3232 no standby power

    got this tv for 10 bucks and when i first plugged it in, it worked fine for at least 6 hours. the next day it would not turn on at all. i dont even get the red standby light when plugged in. i see 165v at the main filter cap, but on CN3 where i should see some pins with 5v i only see a fluctuating voltage going from around 2.7v to around 3v.
    i lifted the leg of what i thought was a diode to test if it was shorted but im thinking that cant actually be a diode because it doesnt have a stripe saying which side is which...and it says J3 not D something...is it just a jumper? why does it look like a diode without a stripe then?

    still not psu savvy enough...what should i test?

      That is a ferrite bead. It's like a jumper, but also with a ferrite bead.
      The black ferrite bead is there to reduce high frequency noise.

      Try warming the board around the areas of C62, C15, and D7 (what is the number of the capacitor right below D7?) with a hair-dryer. If it makes the 5V standby come on, then one or more of those small electrolytic capacitors has/have gone bad, and will need to be replaced.

          dang..would u believe no one in this bachelor pad has a hair dryer?? thanks for the tips...ill go pick one up and try it. the capacitor right below D7 is labeled C19

              Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
              by tvguy12012012120
              This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

              Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

              Finding replacement diode iPad Pro 3rd gen A1701
              by asr
              Hello, I am looking for help to replace a damaged diode. The tristar was replaced and a diode was damaged in the process. I have a picture of the diode but dont have an exact donor. I mostly have macbooks for donors and only a few ipad and iphone boards. Diode part number: DSF01S30SCAP
              Im not sure where to find the ipad board number. Anybody have an idea where else this diode is used on other boards? Thanks....

              TV backlight zener diode
              by unimatrix93
              Hello everyone, I'm repairing an LG TV backlight and I noticed some strange behavior when I touching the backlight strip with a missing Zener diode.

              So I replaced the leds on the strips and they seemingly working fine, but soon as I touch the strip which has a missing Zener diode the whole backlight turns off for a few seconds and then turns back on.

              Is this caused by the missing diode? If so what kind of zener diode should I use to replace it?.
              ​​​​
              The led strips has 9 6V leds.

              Vizio D50u-D1 Dead Set No Standby
              by fharris1977
              Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated.

              Samsung BN44-00259A standby question
              by Crystaleyes
              Hi all.

              I started a thread while back regarding TV power supply standby circuitry as it is something I am not quite on top of.
              SMPS theory and function is becoming more familiar, however the standby part is still a bit of a mystery.

              Anyway, a friend has this TV with the above mentioned power supply board which has no standby voltage, nor any other voltages leaving the board.
              The mains AC comes in fine, gets filtered and rectified with power is on the main filter cap as well as the transformer and drain pins of the ICE3B0665J, but that's it.
