IR Remotes detailed post
Hmm dish told me that you couldn't have two uhf remotes.
Now, with my Sharp 46" lcd tv, Sharp LC-60C46U from costco to be precise.
There are various av mode settings ranging from dynamic, standard,movie,pc, game,user, etc. Each has their own 'backlight settings'. My tv is used in living room, a fairly bright room normally.
The default settings from Sharp seem to set a lot of these settings for backlight "high" (the range is from -16 to +16), so dynamic is set at +16 from sharp, movie +16,game at 0, pc at +12, and standard (which one might think is a default setting only at +5).
Now you turn the tv on (this seems to happen for a time period until the tv is on for awhile, then usually any setting will work, so it is most pronounced for the first n minutes).
**** If the backlight is set at +8 or more, the remote (from Dish 722) works fine. If it is set at +7 or less, (that is +7 to -16), including the standard setting at +5, the remote does not work! Clearly reproducable. If you put a piece of paper over the sensors of the dvr, it works fine at any setting.
Questions:
1) I called Sharp and Dish. Dish sent this to their engineers as tech support does not know. Sharp is having a tv repairman come to the house as they did not know. I want to probably try to escalate at Sharp.
a- anyone know for Sharp LCD 46" (in a regular lit room) what are the appropriate brighness settings? I don't see why the defaults for most are set so high.
b- It seems almost counterintuitive. If IR interference is caused because the lcd tv is sending off higher IR than the dvr can handle , wouldn't a higher backlight cause more IR than a lower one?
c- Do you think this is more of a bug/defect in the amount of IR that the tv is broadcasting, or the sensitivity of the sensors in the dvr (my guess is the second).
Thanks to everyone.
