    Phillips 42PFL3704D/F7

    Set had no sound and did not change channels. All power supply voltages were good. I got another main digital board . He only used the HDMI inputs that are on the digital board. Audio worked for a short time. The A91H5MJC
    analog i/o board with audio amp was only 35 bucks plus shipping so i bought it. It to only worked for a short time. both speaker wires wer 7.5 ohms. not shorted or any resistance to chasis. Tried freeze mist on audio amp transistors. No joy. I can get a menu OSD with either Main Digital Board.
    Am I fighting two bad boards?

      Problem. Was I had gotten a bad main digital board that was supposed to have been good. I will not get any more parts from that site any more. Cheaper is is not always best.
      I do have a spare CBJ board now.

              I had got the main digital board from http://www.tvtechparts.com/
              I waited too long to return the part because my Mom was in the hospital.
              She passed away. Mom and Dad were married 71 years. She was 89

                  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.

                  by m1ch43lzm
                  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...

                  Problem

                  This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                  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"...
