Hello. I've got a mid 2014 MBP with 2.5 GHz Processor + "Dual" Graphics. Looking on the other websites, and in my "About...

First time asking for help?! That’s great, be sure to ALWAYS give the manfuacturer and model information of your device when asking for help online, probably why I’m the first one to respond. The helper community gets pretty tired of instructing people over and over again to : say WHAT they want help with exaclty, model, then problem, then what you’ve tried, then more details. Depending on the model / value of your player, it may not be worth it. Here’s the official repair support page for Sony (my heaping pile…): https://us.esupport.sony.com/support/s/s... I have a BDP-S6500, and it’s not worth a dime if I can’t fix it myself in 20 minutes. It’s been finnicky from the first. Junk I say! My next one will be an LG I think, haven’t tried them in a while… How I fixed mine most recently was use the “Troubleshooting Page” here: Sony BDP-S3700 Troubleshooting Which doesn’t come up on ifixit searches, but does on web searches, or you can navigate to the master page for the DBP-S3700, then click on...

Hey Mayer! This reminds of the ongoing iPhone "Battery" replacement issues... how is it that the "battery" (hardware) needs replacement when these phones were fine until iOS 11 (software)? Conspiracy indeed... I've not gotten the fleet of legacy / upgraded macs I manage onto 10.13 yet, most are on 10.11, but now I think I'll upgrade with great caution. Perhaps do some Geekbench and BlackMagic and/or AJA System speed tests to see if I can find some insight into what Apple is doing here. Did you run HD read/write + processor tests in both scenarios? I'll report my findings when I do this (assuming I remember to come back here...), as now I'm interested in doing this as a test on a partition of one of the machines that will eventually get there... should be able to do this in the coming month. awfulapple!

Not sure if you can re-flash the firmware (FW) to current version or roll-back to a if you’ve previously downloaded & kept the files. On my S6500 I did 1 / 4 of the FW updates via USB, rest on Wi-Fi. It actually seemed more intense on USB. BUT, if you have finnicky wi-fi 1) wire the thing w ethernet 2) use a USB drive to update FW (dl from Sony site). I might also suggest to people that they could be having Router/QoS or Comcast connection/packet interference arbitrarily based on protocols / servers etc. Comcast is also heading up the charge to kill net neutrality. I would switch ISP’s if you can. Look it up.

>>> Sony Servers also MUST be working >for you<! All the apps run through SONY servers then connect to your subscription services. Spying/selling your “behavior data fragments”.

As far as the thing forgetting your passwords and stuff… yes, these things are total garbage and it’s funny sony put their name on.

Also I’d try a static LAN IP, if not too techy, for people losing connection, wired or wireless.

A BIG thank you to the iFixit Student Authors!:

Literally, BDP-S6500 would not power on, until I followed directions in the HDMI Cable section of “Device Not Powering On” above… menu was called something else, BUT… unplugging the HDMI cable from our splitter WORKED. Unit powered on immediately. I navigated to the equivalent option (called something else on this model, of course, thx Sony (eye roll))… it was off of course, because I had never turned it on… but it was behaving in a manner that the solution above solved it for now… I’m so glad their build-to fail attempts on failing on this hunk of junk!
