   I have a Seiki SC-40FK700N TV with what appears to me to be dim   
   backlighting along the top 1/3 of the screen. The lower portion of the   
   screen appears as normal, but about 2 weeks ago the top suddenly went   
   dim; it's still readable, but dim.   
      
   I don't know how many LED strips this TV has. I would appreciate any   
   troubleshooting suggestions such as what nominal voltages I should see   
   where. If it does turn out to be a bad LED strip, should they all be   
   replaced while I'm in there?   
      
   While I do have plenty of experience dismantling, repairing and   
   assembling medical devices and computers, I have never worked on a LED   
   TV. After watching some backlight repair videos, it looks rather   
   straight forward.   
      
   I think that I can find LED strips for ~$15/ea or so, so it may worth   
   fixing this set. Thanks for any help.
