    definition of abbreviation for mother board components

    do you have a list of definition for mother board components.
    example:
    L2
    PQ
    C300
    these are abbreviations commonly seen in laptop motherboards.
    can somebody has a list to identify capacitors,inductors,transistors etc.
    thank you

    Surface mounted components will need to be cross referenced from a schematic to determine their original operating values.

    C300 - 'C' indicates capacitor; 300 is the enumerated index to this capacitor on the schematic.

      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...

      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...

      Help Identifying board components - iMac 2017 21.5
      by 944longdrift
      2017 iMac (Mid 2017) A1418

      I'm not quite sure how this happened but a couple of components got ripped off the board when removing from the Logic Board from the iMac.

      Can anyone help identify them?

      I'll have to do the trace repair on the board before soldering on replacements but would prefer to order the components rather than get a whole scrap logic board off eBay.
      Thank u

      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...

      DVR HIKVISION DS-7208HWI-E1/A BOARD DS-80104 REV 2.2 help identify burnt components
      by thesame
      Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
      The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .
