    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

      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
