I'm fairly certain the problem is some lack of sophistication in error checking and correction/recovery software native to these electronic junkpiles. This is the trigger to most of the problems these RCA abominations experience. The biggest tip in trying to work with these boxes is to try to site your antenna somewhere it almost never becomes subject to propagation anomalies. That may very well restore your box(es) to what limited and sporadic functionality they were ever capable of at best. Experimentally I found the cure on mine-you must pull the power cord out of the wall socket and then depress the standby/on key while plugging the device back in-hold the button down the whole time until you get it reconnected to the mains current.

That sounds like it might be your problem. My worst example often will not come back on once turned off. When there are difficulties one of the first things to try is to cycle the device between standby and on. If you're still struggling with these not-worthy-of-a-warranty-of-merchantability abominations this may be useful for you.

The worst example I have has a particularly annoying defect. Often when a channel becomes temporarily un-tunable due to the transient nature of the propagation these boxes will 'hang' on the untunable channel for minutes before another channel number or up/down command may be entered. Nevertheless these particular boxes seem as if designed to fully-exploit the potential in DTV broadcast 'technology' for creating frustrating unpleasant experiences to the utmost degree possible. Some of this is the nature of UHF propagation and digital stream decoding. None were worth the trouble to go get them and bring them home, much less the many man-hours of frustration and recordings of content when not home which were later found to contain sound/no picture, picture/no sound or continuously appearing boxes stating that the antenna must be repositioned or another blasted scan performed.

Two were purchased with the vouchers and one came from a thrift store-$3 I think.
