    HEP Group LBVC9BI UNI LED driver

    This unit had approximately 50K running hours before it failed; upon opening, a bulging (and heat stressed) TK UTWHM series 450V 10uF unit caused the TOP278 IC to blow its top off.
    Other electrolytic capacitors were a 25V 680uF Taicon HH (output filter) and 22uF 50V Hermei LR (driver circuit), both of which have not failed.

    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

      by osrex
      Hello, this is my first post and im just a beginner, so be easy on me guy. thanks



      i have a LED chandeilier that switches colors from white to cool white to warm when toggling the switch, it has 24 LED arms, each arm is 30 CM length.

      LG 55LM6200-TA country group/Area option
      by notallbad
      This is a 2012 LG TV so aware full functionality of the smart functions/apps will be limited however currently unable to get the LG Smart Store.

      Youtube, Netflix and LG Smart store icons briefly appear in the apps list but then automatically disappear after doing 'Initialisation of Premium' via the standard menu, I'm guessing this is due to the Country/Area group its set to is wrong for the UK.

      Unable to change the country group, Area option can be changed which alters the country group but none make any difference. So believe its the country group that needs changing....

      Vizio E55-F1 dark backlight zones. LED failure or Dimming Zone Driver?
      by howardc64
      Problem

      Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video



      Model & Board Pics



      Conflicting Spec

      Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12

      Repair Success! Middle Atlantic UPS2200R-IP
      by valvashon
      Yesterday I successfully repaired a Middle Atlantic UPS2200R-IP that had inadvertently been used as a surge suppressor at our transmitter site. It has already been replaced with an updated one but it's coming home with me now instead of being e-cycled. To be specific, this is the MA model that has the blue backlit display and has been discontinued, although this design may have been used in many UPS units including the smaller Middle Atlantic ones in this series.



      Here's what happened: We experienced a brownout/surge at the site, which damaged the UPS and took our broadcasting...

      Audio Driver for Thomson P14C4BK128
      by charif
      Need Audio Driver for Thomson P14C4BK128 (Windows 10/11)

      Hi everyone,

      I'm looking for help finding the correct audio driver for my Thomson P14C4BK128 laptop.
      The sound is not working properly, and I believe the audio driver is missing or not installed correctly.

      Here are the details:
      • Model: Thomson P14C4BK128
      • Operating System: Windows 10 64-bit

      If anyone has a working link to the driver or knows where I can download it, I'd really appreciate it.

      Thanks in advance for your help!
