I'm sorry, but I don't have any schmatics of your vcr. The control chip is normally the one hooked directly to the head motor. It is replaceable if you can locate the part ( some vcr [parts are obsolute). Good Luck with your project

You just have a dirty main video head. You can get a head cleaner tape or you can buy a tin of Servisol Video 40.
To clean with the Servisol, remove the top cover of the VCR. You will see a big shiny video head. Spray that head with the cleaner. You can also wipe it over with a cotton bud if it is very dirty. It's a good idea to clean all the surfaces that the video tape touches. If you don't know which, when you first take off the cover with the VCR on power, put a video tape in a press play then watch where the tape runs. Eject the tape, then clean with the spray and a cotton bud. You can even spray the cotton bud and then clean with that if you are not happy just spraying into the unit.
Make certain that the sprayed areas are dry before trying a video. It dries very quick anyway.
It sounds like you have a dirty video head, you can try a wet or dry cleaning tape, I recommend a dry tape because it is easier on the head. The second option is run a brand new T120 tape and set the speed at sp (2hrs) let it run the full time.
The problem is not with your TV. I have had this problem as well and the older the VCR gets the harder it is for it to turn the tape. Does your VCR react the same way with other tapes? Try Fastforwarding the tape about halfway and then test it again.
I assume you have had this player a while and I assume that all the programs that work without snow are ones that you recorded using that VCR to do it. Right?
If so, it is a compatibility issue where the last time you had it fixed, the repair guy did not check for VCR to VCR compatibility. I had a shop for 15 years and this is common.
Do you have a Tracking control? try adjusting that. It is either a physical control or part of the menu, depending on that specific model.
Last...last is to open the unit and you must be very very careful. Put in a tape that is from another player that plays snow and identify the shinny rotating head if you can physically see it. It sits at an angle and the RCA is typically in the back middle, about an inch in a half in diameter. While playing press your finger very very lightly in the middle of the shinny exposed video tape for like 4-10 seconds and maybe the snow will go away.
Your video head may be worn or dirty. Do not attempt to clean the heads the are verrrry delicate.
3. Try finding an old VCR cleaning tape. It does the same thing as your finger.
Are you absolutely sure that it is receiving an audio signal?
What input are you using? Try recording using alternate inputs.
Audio part of a VCR is normally way more reliable than the video.
The exception is on high-end stereo types where they record the extra
audio signals using the video head cylinder in which case it can easily
Error 2 and error 3 and error 4 are tech codes.
and if your unit won't reset, you can take it to your local
electronic repair shop. I had error 3 on my Phillips,
and he went to the PM webpage,researched it, and fixed it perfectly for $39.00 total. STILL WORKING!
He said it was some little thing to replace that took him 15 minutes.
If you don't want to buy one of the REALLY cheaply made vcrs or DVD/vcr combos that are out now, it worth a little phone time to find
an electronics repair shop. Or the new DVD recorders with vcr combos are very good, but sturdy ones are expensive.
First, have you doublechecked the video hookup? It sounds like you are using the video/audio inputs to the TV, so make sure you have VCR video out cabled to TV video input, and the TV source/input selection set to that input (video 1 etc.).
If this checks out, check for a dirty video head on the VCR, though a dirty head usually results in a blank or blue video display (older VCRs, snow).
You could do a process of elimination by hooking VCR to a different TV and see what is displayed then.
Lastly, I assume you've tried multiple tapes, just in case a home recorded tape was incorrectly recorded?
On some TV's the screen will go blue if there is not a strong, solid video signal present. This is to prevent the showing of very snowy or all snow channels, or garbled, mixed-up external video signals. This is normal. On some VCR's the video signal changes when the FF or REW search feature is used, and this could trigger the TV to go to blue screen. The only way around this if you can enter the TV's menu and turn off the blue screen feature.
