  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.....

  Samsung OLED QN77S90 Bad Power Supply

  by cheebster

  Hello, picked up this tv a nice Oled QN77S90. However, it's blowing fuses like crazy (got the whole room lights go out the first time). So i digged and it seems this tv has the BN44-01264A PSU that often fails. However, replacements are costly (samsung replaces it for the BN44-01329A revised psu).
  
  I'd like to troubleshoot that one. Here is a picture of it, but honestly i don't know where to start. It blows a 12A fuse in a split second, it's really a hard short on this one. Thanks for any guidance ! ...

  Hisense LCD42W60P Television

  by angelos

  Hi Guys,
  I have this 2008 lcd tv that uses ccfl lamps. The tv is stuck on standby. This is what I have noticed. The standby 5Vs voltage is not 5V but rather 3.28V. There is a 14V rail as well but that measures ok. I put my volt meter on the 5Vs rail and switch on the 220Vac. I noticed that the 5Vs rail goes to 5.1V and quicky changes to 3 28V and steady.
  I unplugged the main board and ccfl lamp wires and tested the power supply separate from the tv without load and put a 470 ohm resistor to the stby rail to force the tv on.
  1. Pfc circuit activates and mains smoothing cap is...
