    JBL Flip Essentials - Bluetooth not connecting after a fall - video of board

    video: https://www.youtube.com/watch?v=S-xBu7m6SwE

    Hi all. I was given this JBL Flip Essential speaker that 'fell from about 8 feet' and then the bluetooth would no longer function. It seems to power on normally and responds to button presses, but it will not showup on bluetooth for any device I try to connect to it.

    The bluetooth daughter board has a 26mhz oscillator that I could not get to read the proper frequency so I tried replacing that to no avail. Thought maybe something was wrong with the bluetooth IC it's connected to, so I tried replacing that as well. None of the caps in the area are shorted out, the inductor on the daughter board reads a very low resistance. My biggest qualm right now is not being able to read 26Mhz on that oscillator, I can't seem to figure out why. I know the chip is getting 3.3v. The closest datasheet to the Bluetooth IC I can find is this https://datasheet4u.com/datasheet-pd...php?id=1152019 (actual model is WS9623ADSFF) and I cannot find a schematic for the JBL Flip Essential at all.

    I did not see any missing components as I went through the board. There was one SMD electrolytic Cap that was ripped from the board, I'm guessing I did that by accident opening this thing up, but I have reconnected it.

    Any advice would be appreciated!

    thanks

      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.

      HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
      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....

      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
