I own a Panasonic TH-42PD60U. I recently had a problem with what I believed to be my tuner and cable company playing nice. My tv firmware version was 0102-0010 meaning I had tuner version 100 and eeprom version 120. After reading many threads about QAM channels not locking in properly I ended up looking to Panny's site for a firmware update. There were 3. One for the tuner, one for the eeprom and one for the vchip ratings. I updated to the latest and my problem is worse then ever.

Problem - digital (QAM) channels that my cable company broadcasts in the clear do not get picked up by the auto channel scan. I need to manually punch in the root channel and then I can select the subchannel. Since it was not picked up by the autoscan, it will not stay in my lineup. If I punch the root of a separate channel the first one I was watching goes away.

Worse problem - after upgrading the firmware, I can no longer tune the subchannels that are not picked up by an autoscan. If I punch in the root channel, I can see and hear the program until the channel is finished scanning. Then it says the channel is not available and goes black. After a minute it will clear the subchannels and put me at the first analog channel in my lineup.

Does anyone know where I can get an older version of firmware to try and at least get back what I had? Anyone else have a similar experience where the upgraded firmware scanned less channels? Some channels still come in perfect so I know the QAM tuner still works.

Panasonic's QAM tuner sucks, other Tv's i have Samsung LCD and a LG3510 tuner compared to them it takes forever to scan, it picks up channels with nothing on them i assume if you have say channel 90.1 it will show all 90.2-3-4-5-6-7 even if at the time of scan theres nothing on, takes forever to delete all of them as you cant watch in the lil screen in upper left corner.
I doubt you can go back in firmwares, complain to panasonic, doubt they will listen.
