electronics purgatory  
After ages of toting the components around and not bothering to set them up, I decided to put my stereo together and run the TV through it as well, as part of my general "use it or get rid of it" purge plan. This ran into some obstacles. That my receiver was so old that the TV would have to be run through the phonograph jacks instead of a Aux for the TV I knew; that it was so old it didn't have a remote was not very significant given where it will be positioned in the living room. That it was so old that the plastic seatings holding several sliders had deteriorated and would snap upon being slid, was a surprise.

I decided that given it was only the treble and bass sliders, I could simply leave them in midposition and plunged on, only to realize in some move or another I had detached all the wires and since lost track of them. Goodwill or the curb and buying one of those cute little all in one stack stereos when I get a job was looking alluring, but I think I'll visit Radio Shack instead.

a problem with your plan
It won't work to plug your TV into the phonograph jacks.

The voltage levels of the signals coming from your TV are much higher than the levels from a piezoelectric or magnetic phono pickup, and the impedance of the TV's output is likely to be way low compared with the phonograph.

Also, phonograph records and pickups were deliberately recorded with amplification varying with frequency using a formula for the variation called "RIAA Equalization." All phonograph inputs have a circuit built into them which accommodates the required variation in amp. with freq., and a TV's sound output will be trashed by it. This is the opposite of the problem where you can't play back vinyl by plugging your turntable into a regular AUX input.

If the speakers' wires that you have with this setup end in RCA plugs, you probably might as well drop off the speakers with the rest of the stereo, since they're unlikely to work properly with a new amplifier or stack stereo when you buy it.

Sorry to be the bearer of bad news, but maybe I've saved you time and trouble finding out by experimentation that it doesn't work.

Re: a problem with your plan
The speakers are new and regular speaker wire type, actually. Not terribly expensive ones, just a pair of bookshelf speakers I brought.

It sounds like I should check craigslist for someone dumping an old, but not as old as mine, receiver. The tape deck and CD player are perfectly adequate, so I hate to toss them out to get a whole new ministack system. It seems wasteful.

Hmm, there's a Pioneer SX255R receiver on craigslist for $25 that has Phono, Tape 2 Monitor, Tape 1/VCR, LD/DVD, and CD inputs. I assume that would work for chaining in my TV somewhere?

Re: a problem with your plan
Yes, if it works in general it should work for your TV. Any of the inputs you listed (other than Phono) should be a match for a TV's line-out. A good find!
