Hitachi Rear Projection TV - No audio on inputs, except Static on Antenna
So I rescued an old TV from the trash, appears to be a Hitachi Rear Projection TV, no obvious model number available, and when I try to power it on, it will display just fine, but it has no audio coming out UNLESS I turn it over to antenna input, in which case it has bone rattling analog static. This is the US where everyone changed over to digital television, so not super helpful, and while I could do some sound splitting magic, that seems like a waste if there are already good speakers. So I have come to you, honored Tildos, for assistance in pointing me in the right direction on whether or not this television's speakers can be saved.
Old electronic tech here. Without schematics and knowing what to test for, you'd be hard pressed to be able to do anything to it. Only suggestion I have would be to see what socketed chips you could reseat, try unplugging and reconnecting all the plugs inside (with the power removed, of course). In our old Air Force mainframe computers, a reseat often fixed faults.
Without getting it fixed, you could put an amp in it tied directly to the speakers, bypassing the TV's audio.
Yeah, I have a Roku with Composite Audio, so that was my plan B, just thought that it was odd that Static plays just fine, but Audio doesn't, so I was wondering if it was a setting or configuration error. Thanks for the insight though.
Bit of an update, found out it is a Hitachi 51f710a, audio works on composite after I put a VCR on it, and I trawled the menus and manual for something to fix it, but nothing obvious seems available. My old Roku will still do HDMI with Composite Audio out, and when that goes, the Roku Soundbar seems like a good step up.
