I found a Panasonic TV (TC-32LX70) in the big garbage bin in my apartment complex it works fine
but it looks like it has the known power on problem with the firmware. Here is a Link
to the firmware install guide. I have a couple of questions though
1. I know I have to use an SD Card that goes into the Service Slot (I found the slot on the back of the TV but it is not obvious which way the card goes into the slot
2. How do I determine if the firmware actually needs to be updated?
