    Sony vpcsb cable from power board to mothernboard

    Hello. I have a sony vpcsb (mbx-237) here that seems to have a defective flexible cable, the one that goes from the power board to the motherboard. The computer would not turn on, but after moving the flexible cable around it started to work. It only works if the power board is out, and the flexible cable stretched a little.

    I see from the schematic that most of the cables go to Ethernet and other thing I do not need. Does anybody know what are the absolutely necessary lines to power on? I have searched for the cable but can not find it here in Mexico, even online. I will order one from the US, but it will take more than 2 months to arrive.

    PS.After moving this cable around, it does not work at all anymore, when connected I do not get 19v to motherboard, when it is disconnected I do get 19v.

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

    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...

    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"...

    A1312 (27” iMac 2009-2011) A1407 (Thunderbolt Display) A1316 (Cinema Display) Display Black Screen Repair

    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

    Sony Vaio SVS MBX-261 board failure
    by delpiero3
    Hi everyone, newcomer in this forum, i watched tons of video from Sorin, i like the way i calmly explain things, i did quite some console repair, i am not that bad at micro-soldering, but troubleshooting where the issue is, is definitely where i still have progress to make. Usually i was able to fix the console because the failure was obvious, or because i was able to find someone with similar measures on the board and was pinpointing what to replace that way.
    Nevertheless, let's say, i don't come as a total beginner.
    I have this old laptop, which suit perfectly my needs, with the...
