My BD390 started having a "Disc Error" when trying to load about half of my BD collection, and the ones it would load would freeze after a few minutes. I am feeding it with clean power (Belkin AVU1500, a $1500 MSRP UPS and power conditioner), and it is in an actively-cooled Mid Atlantic rack. I have the latest firmware.
I went through the following to try to get LG to repair/replace my unit:
1. I went to the LG website to fill out the warranty claim form. I submitted all the required info (serial #, contact info, where/when I bought it, etc). I got no confirmation email, and no one ever called me. My claim disappeared into the ether.
2. A few days later, I tried the LG online support chat. The CSR found my claim in their system, but they had done nothing to process it (waiting for me to contact them again I guess?). He told me that I was outside the 90 day labor warranty, but inside the 1-yr parts warranty, so there would be a $69 labor fee. I protested ("can't you just swap it out for a refurbished unit for free?") to no avail. I already spent $300 for the player, it was either pay the $69 or be stuck with a $300 paper weight. He processed my claim online, but said he couldn't take my credit card payment over the web, so he gave me a number to call.
3. I called LG support. First lady I talked to (in the returns department) said she wasn't able to process my repair payment, and transferred me to someone else.
4. The second person made me recite all my info (Case #, serial #, contact info, etc), only to tell me that she ALSO was unable to process my repair payment. She put me on hold for 15 minutes while she tried to find someone that could.
5. The last lady was actually able to take my repair payment, but she was obviously chewing gum the entire time and was very unprofessional.
I still haven't gotten any kind of confirmation email from LG, but presumably they are snail-mailing me a pre-paid shipping label for my return (can't they just email that?). At least I don't have to pay shipping.
I'm expecting to be without my player for at least a month (shipping time to wait for the label to be sent + shipping time to LG + repair time +return shipping time), so I just gave in and ordered an Oppo BDP-80. I'll rely on the LG to do streaming or just buy a $100 Roku player (that actually has Pandora, unlike the LG).
I wish the Oppo was available when I bought the LG, because I would have gotten it instead. Oppo has a better warranty, a better support department, and supports DVD-A and SACD. Wireless and streaming capability aren't worth dealing with LG's poor quality and lousy support.
