Loud high pitched noise coming from converter box?
Bought an Apex converter box about 6 months ago and it's worked pretty well up until about a week or two ago. If the box is not in use, it'll automatically power down in which I'm assuming is power saver mode. I don't mind this option so much, except in the powered down mode, it makes a loud high pitched humming noise coming from the converter box unit itself.
Could be the power supply. i'd be taking that one back to the store. mine goes into power save every four hours but it shouldn't make a noise like that. that usually means the transformer in the power supply is arcing and it will fail soon. it's also a fire hazard. there's a rumor that most Apex branded boxes are bad. i don't have any way to say since mine works fine but if it's making noises i'd be taking it back. DTV isn't worth your home burning down.
