If you're having problems scanning in the HD tp's, it's likely that your satfile is outdated. I'll give you step by step instructions to check, and convert if needed.

1. Hit the menu button on the remote.
2. Go to "Installation". Enter PIN code 0000
3. Select "Channel Scan".
4. Use your right/left remote buttons to get to the sat that you want to edit.
For this example, we'll say you want to edit sat 129, so select EchoStar 5.

5. Turn Network search "Off".
6. Scroll down and highlight the EDIT TP icon (It's the one on the left and it should go to it first. Press "OK"

7. If you're using the default satfile, TP 12268 is out of date and thinks that SD channels are on it, and actually it's a HD TP, so use your up/down arrows until you get to 12268.

8. Press the F2 button on your remote to "Edit" the TP.
9. Right arrow once to highlight 20000 and type in 21500. The highlight will automatically move to the Polarity entry. It should not be changed.

10. Right arrow again to the FEC field.
11. Use the up/down arrow until you have 2/3 in that field.
12. Right arrow again to the MOD field.
13. Up/Down arrow until TURBO8 is showing.
14. Press your Exit key.
15. Scroll down to the next TP that you want to edit, then press the F2 button again.

16. Repeat steps 9 thru 15 until you've got them all done. Then rescan.

Note: If you want, you can press the Exit key after each TP. It will ask if you want to save, select Yes. Press the OK key and it will scan the TP you just edited. I like to do it this way so that I know I've got it right.

Give it a try, and post your results. You'll want to use lyngsat to find which TP's should be HD and need to have these settings.
