2 ipossibly related issues. About every 6-9 days, when I turn 722K on in the morning, it displays a different channel than the one that was being viewed when I turned it off the night before. It is always the same two channels: 640 (TV Japan) when 722K is turned off with the remote, and 345 (Encrore Drama) when 722 is turned on with the remove the following morning. The second issue: When this happens, I enter 640 from the remote to change the channel, the 3 numbers appear on the TV screen, but 722K does not switch to 640. Do this several times, but no channel change. Then enter another channel - 6308 for example (local NBC station) - and 722K switches to that channel. Then enter 640 and 722K switches to 640. Has been happening for about two months. Current software level is L750, but I do not know how many times its changed over the past two months. "Grasping at straws", I changed the remote's batteries - they were about a year old - but that made no difference. The first one is easy to live with, but the second is a bit of a pain. Will appreciate any thoughts as to the cause of each issue.
