Make sure that the TV's AC cord is plugged directly to the main outlet, and not through the decoder box (dish box).
Many models of TV sets, when switched off, if they loose the AC supply, the default user memory will be re-set to the default.
If the TV set is being used properly, it is possible that there is a defect with the internal memory of the TV set in the area that works with the user set-up. In this case, the set will have to be serviced. Some sets use an internal battery, while some other's use an internal memory built in to one of the microcontroler chips. If the fault is not directly from a memory battery, then servicing the set can get fairly involved.

I got a used 1992 Phillips 21" set. Set it manually to channel 73 for Dish
Network, to replace a smaller set at the same RF connection. It worked
normally with Dish Network, where the remote changes channels. Turned it
off, still plugged in and connected to Dish Network.
Next day, turned it on, it did not retain the previous channel 73 setting,
had defaulted back to channel 2.
The smaller older set was a 1985 Toshiba, but it retains the last channel
setting used, like any other TV I've used.
Is there a problem with the Phillips, or is this common in newer sets?
