Sylvia is LC320SL1 seems to have a mind of its own first the volume increased without any input from me and now the screen goes through channels, video, components without generally stopping on any function or channel

SOURCE: Unable to record one tv channel while watching another tv channel

You CAN record one channel and watch another with satellite service, but it would require two separate DBS receivers. The issue is that all satellite broadcasting is encrypted until it hits the receiver, which decodes it and transmits it outward toward your other AV devices. If it weren't for the receiver, connecting the coax cable to your other devices and trying to tune channels with them would yield no signal and possibly much frustration. You would need to split the signal into each receiver and have one connected to the television via one input and the other to the recorder then to the TV via another input.

With cable, you can split the signal without having to have two boxes - this way the QAM tuner in the cable box is still capable of tuning channels while the recorder can tuner basic cable channels for recording separately. You can also have the cable box connected to the recorder via composite so that you can record premium stations on a DVD recorder input mode anytime you like - but you would have to be watching that channel at the same time unless the DVD recorder had a pass-through RF signal (rather than a composite clone) - meaning you could also use coaxial to your television from the recorder and tune channels separately on your television while the recorder is recording one channel.

A lot of what-ifs there, but it is all quite possible.

It could well be the accumulation of dirt/dust behind the buttons causing them to stick. If you are able to carefully remove the board that the buttons are located on and use a cleaner that will de-grease at the same time. Be sure that everything is dry as can be before re-assembling and then check if the problem persists. If you are not capable of doing this trust a competant technician. Hope this helps.

SOURCE: input channel with no remote

You should be able to select the AV input with an Input or Menu button on the front of the TV.  If there are no arrow keys the Channel and Volume buttons may provide up-down-left-right action.

Whew! Found the NE116UD replacement for the EWF2704 Emerson TV (there are other models on the list as well), it can be ordered here for 24.95:

Hope that helps. This problem is certainly very irritating. I have never heard of a remote for 24.95, nice job Emerson -- never again!

Hmmm a wild guess perhaps you should try to add channel 0 (zero)?
