I have an old VCR its a Hitachi F361 Digital Audio Tracking with Hi-Fi stereo. Its hooked up to a electrohome tv thats 20 years or more old. I use the VCR (and its remote) to watch tv. The volume on the tv has a highpitched buzz that changes depending on the volume level. But lately when I turn the vcr on towatch tv over top of the high pitched buzz is a scratchy "buzz thats very loud and changes randomly (and is not affected by the tv's volume setting). I only hear this newer scratchy buzz when the vcr is on. I tried checking the cord connections, wiggling the connections, and propping up the vcr at a different angle hoping that would solve the problem. There also seems to be a correlation bettween the tracking lines on the vcr screen and the scratchy noise, when the lines increase so does the noise. Any suggestions on how to fix this are greatly appreciated.

The hi-fi sound goes first. There is nothing you can do about it. Unless some special recording techniques were used, you always have a linear sound track too. Try to adjust TRACKING on the remote to hook up to the hi-fi track.
Normally the tracking control is on the remote control. Some models do use the up & down channel selectors on either the remote or the front panel of the VCR. If you don't have the remote, the best way to test if it is these controls on the front panel, is to start a video playing a hold down the up or down key and watch to see what happens. If they operate the tracking, the tracking should go way off (do it on a video that is tracking well when first playing).
PS don't forget to clean the video head every so often (Servisol video 40 spray is best for that).
You will need a converter to record onto a VCR. I can't remember the when the FCC require VCR to have digital, but I know yours old enough it has an analog tuner. Take your antenna connection to the in on the converter box, then you can take the out from the converter box to the in on the vcr and finally take the out to tv to the tv. To record you have to have the vcr on 3 or 4 and use the converter box to do the channel changing.
Another way would be take the in to the converter and use RCA cables to the line in on the vcr, and line out to the to the tv. This will give you stereo sound.
Such a simple job. First check if the cables are connecred properly 1. Audio OUT from VCR to AUDIO IN of TV. 2. Video OUT from VCR to VIDEO IN of TV
Then switch the TV ON. Select 'Video' on the TV/Video selection button on the TV's remote control. Your TV screen will show a display like 'Video' or 'AV' Play a cassette and you should be able to see the picture... Happy Viewing.
I had the same problem when I got the TV from someone and I didnt have a remote. I went out and got a ONE FOR ALL remote and once I got it set up I had it in VCR mode and hit the AV button and now I can get to the channels. Hope it works for you.
The noise from the TV is called 60 cycle hum and it is caused by a capacitor that is open, a test for ripple voltage will confirm this The noise from the VCR is more then likely common mode noise which would not be heard but for the bad capacitors in the TV. Simply put the common mode noise is being added to the 60 cycle hum. Now for how to fix this, if you have a background in electronics you can use a schematic, multimeter and an oscilloscope and Multimeter to find the bad capacitors, and the schematic to tell you what the voltages and %ripple should be. If you do not have a background in electronics, take the set to be repaired
The "crackling" sound you describe sounds suspiciously like mis-tracking. That is: The result of the Hi-Fi heads (which are on the rotating video headwheel or drum) not exactly following the recorded tracks. Have you tried adjusting the tracking slightly? The reason this happens is that the Hi-Fi tracks are MUCH narrower than the thinnest video track (used for 6 hours per T120 tape). Tape stretches and shrinks as it ages. Video recorders wear with normal use in such a way that the tracking changes.
The problem is often worse with tapes recorded at the SLP (6 hour) speed because the servo cannot correct errors as fast when the tape is moving slowly (on some machines only). Tape quality also counts...and manufacturers change their formulations without public notice. All these things can lead to "archived" tapes being lost. Solution: Use the best quality tape you can afford, not the cheapest; record at the highest possible speed. Store the tape carefully. Never use a cheap "rewinder" because they can over-tighten the tape causing wrinkles, stretches, and
other kinds of damage.
