And no tech I know will do that since it can brick the TV and cost or force a board change. The lesson is repeated many many times with folk that "found a way" then flame everyone about bricking the TV and no support for reflashing a bricked board.
This is a nice Plasma set so don't take a chance here. Do what others do and get a Roku or such.
I have a Panasonic Viera TC-P60GT50 plasma TV on which the Netflix app has stopped playing any content, providing the error "We're having trouble playing this title right now. Please try again later or select a different title." and error code aip-705 (with aip-701 occasionally thrown in as well). All other functionality in the app works fine - browsing, rating, searching, changing settings, etc.. All other functionality on the TV also behaves as expected.
I've tried logging out of the Netflix app and logging back in, resetting all TV settings to factory defaults, confirmed that the firmware is current, and contacted Netflix support. Their response was that the firmware had been corrupted on the TV, impacting the Play Ready folder and thus preventing any content from loading. Unfortunately, because the firmware is current, I don't seem able to force an overwrite. (No option to download it in the TV over the current version, and attempting a rewrite from SD card or USB stick only results in error "Please check FILE in media.(0004)", whether FAT formatted via Mac OS disk utility or SD Association utility.)
In addition, I’ve performed a self-check on the TV (Vol- on the TV plus 3 second hold of “Menu” on the remote), and the “PEAKS” line is red. All other entries are white. From the little I’ve been able to find, this points to either the firmware or EEPROM.
Any feedback on whether a firmware update is really likely to solve the problem, and, if so, how best to force a rewrite when the installed firmware is already current would be appreciated.
