Note: We've had one report where the clock locked back up after adding the TVGoS channel back. We think this may happen if the station hasn't removed their TVGoS equipment yet (even though there's no guide data anymore). But this procedure may still get your Pal to auto-load guide info from the stations PSIPs instead of the nonexistent TVGoS, so it's worth a try.
As a last resort, a factory defaults reset should purge all memory of TVGoS from your Pal. Just don't enter your Zip code when prompted (leave it at 00000). The Zip was only used for TVGoS.
I'll try to clear up this 00000 zip code confusion since I was the one who originally suggested it. when I suggested setting the zip code to 00000 it was only intended to be done following a Factory Default.
The way TVGOS works is that you set the zip code. The TVGOS device will then receive a zip code packet. If the zip code packet matches your zip code, then you receive a timezonepkt. It is this timezonepkt that causes the DTVPal to gray out the clockset field, and report that the clock has been set by TVGOS. Once the DTVPal has a timezonepkt it is very difficult to get rid of. Apparently if you push enough buttons, and delete your host channel enough, and do enough soft resets, then you may eventually lose the timezonepkt. The easiest way to get rid of the timezonepkt for good is to do a Factory Default (which wipes all the TVGOS data), and then leave the zip code set to 00000. Since 00000 is an invalid zip code, it will never match the zip code packet, therefore the DTVPal will never receive the timezonepkt.
Setting the zip code to 00000 after your DTVPal has locked the clock is pointless. If TVGOS is gone in your area, then you don't even need to mess with the zip code since it is only used for TVGOS. If you really want to unlock the clock, and guarantee it won't lock again, then the Factory Default is the only way to go.
Here are the steps to prove that a timezonepkt is what locks the clock:
1) TVGOS must still be available in your area.
2) At 10 minutes before the hour, do a factory default, and let the installation wizard run.
3) Turn off the DTVPal until 10 minutes after the hour.
4) At 10 minutes after the hour turn on the DTVPal (you do not need to be tuned to your host channel, the second tuner will have already found it), and go to the clock set screen.
5) Verify the clock is still unlocked (for even more fun, you can set the timezone to something other than your own).
6) Now wait... at exactly 15 minutes after the hour the clock will gray, and the DTVPal will report that the time has been set by TVGOS (if you changed the timezone from your own, TVGOS will point out that you have set the wrong timezone, and offer to fix it for you).
Timezonepkts are sent out twice an hour, at 15 minutes, and 45 minutes after the hour.
