    Polaroid FLM-373B strange power problem

    Ok friend gave me a Polaroid FLM-373B to look at.

    He had the typical bad caps on power board and replaced them.

    he then unplugged it to blow dust off of it.

    After doing so he plugged it back in and there was no problem what so ever.

    When I looked at it this is how I get it to come on.

    I gently plug the AC power cord in the back of the tv till I hear a small spark. then the red light comes on then i push power cord all the way in and the tv works no problem.

    If you just plug the power cord in no red light, but if you gently push in until you hear that little spark the red light will come on.

    I am thinking it is the part the power cord plugs into that is bad.

    What do you think

    I have never seen this before

      Sounds like you've found the proble. Open it up and post pictures. I have a few of the 32" Polaroids with broken screens sitting around. I bet I have a few of those power adapters too.

        Is that a removeable power cord? The poniter in the picture looks to be a fuse holder, it looks like an IEC inlet with built-in fuse holder.

          Yes, it is a removable power cord with the fuse holder.

            try another power cable.

            the connector on the tv has solid contacts,
            the one on the cable has spring-loaded contacts that may be bent and are probably burned from the sparks.

              Try another cord as suggested, inspect the solder on the inlet terminals, reseat the fuse folder.

                  Problem with LG Plasma 60PM6700 - Random power downs
                  by theone111
                  I have an LG Plasma TV 60PM6700 for the past ~12 years.

                  In the last ~3-4 months I have been having some issues.
                  1. Problem: It started with random picture disappearing (sound still worked).
                    Frequency: Happened about once a week.
                    Solution: Had to turn off TV wait a few seconds before turning it on again.
                  2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                    Frequency: Happened about once a week.
                    Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
                  3. Problem: TV shuts down

                  When I reflash again the bios of hoaca388 the unit powers on and the unit lives!!! Hooray!! All voltage in the coil 3.3v, 5v and 6.7v indicate charging are all present. including the cpu voltage , EEPROM and GPU voltage the unit is now alive, normal screen booting to windows and log in screen until I power it off. Then the unit never goes on even when pressing the power button in the keyboard.. Voltage reading 19v main , 3.3v VCC in IT8225E-128 and EEPROM VCC 0 volt and the charging voltage 0 volt.

                  Try to trace the power switch button goin to the power switch IC PU8803 (APL3533AQBI-TRG)...

                  LG OLED55C9PUA power problem
                  by EazyBone
                  Hello, trying to fix C9 55 inch. I have pulled the back and all looks completely normal with nothing burnt so far. This is first time attempting to fix a tv so any help is appreciated.

                  Problem. I hit power button, red light on TV turns off and tries to turn on, no picture shows up and then shuts off. This occurred after house power turned on and off, not from a storm.

                  I have tested the power going from power supply to main board, all 12v and 20 volt readings are proper when I hit power button.

                  The power supply to t con is different story.
                  This...

                  Help please..Lenovo ideapad 5 14itl05 power and charging problem
                  by Dr.d
                  I have a lenovo ideapad 5 14itl05, board LA-K321P, That will only power up on Battery only, or with battery disconnected and power adapter only. If battery is connected and usb-c power plug connected. It only works on battery and will not charge. I can however force it to charge by connecting the battery from a disconnected state while the power USB c plug is powering the laptop.

                  Additionally....to add to this strange situation. The usb-c power plug ONLY works to power the laptop on one side when inserted into the boards power usb c plug. If you rotate it 180 degrees, the board gets...

                  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...
