Terrible Quality Control & Last-In-Class Customer Service
I've been trying to get a decent panel from LG for over a year now. Each time, something has been wrong with the TV I received. In this instance, I had strings of dead pixels lining the top of the screen. After an authorized repair, the problem became worse, but now LG is refusing to authorize a second repair or do anything to help me. After dozens of hours on the phone with customer service, I've given up. I'll be going with Sony, Panasonic or Samsung for my next TV purchase.
