The following is a snip of the post I assume you're replying to and I put it here to put this post in context, since we wouldn't understand which codes you're talking about without it...
All I can say is GOOD LUCK ON THAT ONE, been down that road and decided I needed to move on with life!
codes I would try (in order of increasing danger!)
147 412 356 Warm Reset
653 214 741 Cold Reset
653 274 147 System Reset
No, it's a COLD RESET, equivalent to you rebooting your PC.
NO, it's a System Reset, which is what you should try, equivalent to reinstalling Windoze, Linux, etc.
Google search one night, long ago, for a particular TVGOS code. Don't recall where it came from although I also see one on Spiff's new Forum.
It's a WARM RESET.
It's funny you mentioned this...I actually did this last week after having no luck trying to pull TVGOS from my local CBS. It didn't take but few minutes to relabel the inputs and add the tweaks, but it didn't solve my Guide problem. No biggie since I don't use the Guide with this set, but my Sony HDD500 is pulling TVGOS from the local PBS analog station and I am in no mood to force it to pull data from CBS station right now. I think I may contact the local CBS O&O.
