  New Members - please post your introductions here

  by petabyte

  As this is a brand new forum, I thought I'd open up a thread to encourage new members to introduce themselves a bit.. now hey.. let's not get too personal.. ok ?
  
  And if you wouldn't mind to keep this thread \"clean\" let's try to keep the the chitchat (i.e. even the welcome to the board replies) to a minimum or this thread may get to 100 pages fast
  
  So I'll start things off :
  
  My name is petabyte and I'm a forum junkie. :oops: I've been off the wagon for a number of years and countless times I've tried to stop but it's useless.....

  2+ year old TV with many (720? 65" version has 720) mini LED dimming zones. TV boots, has sound, panel picture can be seen with flashlight. No backlight. No TV model sticker on rear panel (Maybe Samsung service removed it, read below). Found the model # through the PSU and zoned LED driver board numbers.

  KENWOOD KA-701 POWERS ON, NO RELAY CLICK

  by rccrasher65

  I'm looking for some help, sorting out a protection circuit fault on my Kenwood KA-701 integrated amp. The amp does turn on , but the relay don't click.
