    Appliance PC Board Protection

    If this inquiry is posted in the wrong forum or site, my bad.

    BACKGROUND: Several home appliance PC boards have been damaged over the years – dishwashers, wine coolers and oven. I'm no expert but it is my feeling that appliances with PC boards and without a manual on/off switch are particularly subject to surge damage.

    Now, each appliance is protected with an internal surge protector whenever possible. A Whole House Surge Protector has just been installed in the electrical panel for external surges.

    QUESTION: The oven Control Board (Whirlpool OEM Part #71001872) has just been replaced – damaged prior to the external surge protector install. The oven does not have a manual on/off switch, just a keypad. I think it is vulnerable to internal surges. There is no way that I know to add an internal surge protector for the oven. The oven power is hard-wired.

    Any suggestions to add an internal surge protector appreciated.

    Regards...Bill

      Your TV is also does not have hard power switch (very rare now to have power switch that actually cut off the power to the TV completely), just soft power switch. Same thing for your monitors and computers.
      The TV has standby power supply that runs 24/7 same for the processor on the TV's main board. TV power supply only use a small MOV for surge protection.

          Get POCO to check for open neutral. You're only masking the problem with those TVSSes, and those of questionable quality can burn up attempting to "re-balance" your service.

                  kaboom, thanks for info on open neutral.

                  It is over my pay grade; will have electrician check it out.

                      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...

                      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
                      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

                      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                      by howardc64
                      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                      LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
                      by Hakuu
                      Hi There,

                      This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

                      After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

                      More Details

                      TV Model - LG OLED77G1PUA

                      Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

                      Sony xbr-65x900c main board issues?
                      by jb_Bak
                      Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                      Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
                      Power Board Connector that goes to Main board
                      CN6401
                      Pin 01 NC
                      Pin 02 NC
                      Pin 03 "BL_ON": 0V
                      Pin 04 "N/C"
                      Pin 05 "STBY 3.3V": 3.5V
                      Pin 06 "GND": N/C
                      Pin 07 "AC_OFF"...
