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

Vcr hi-fi light blinking


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.

Toshiba modelsd v392su dvd sound and picure perfect vcr SOUND GREAT NO PICTURE and I have done all that is needed to review all inputs to make sure thye are in and i know they are in the proper...


DVD produces a great picture with sound - but the VCR is not producing a picture? is it snowy? or a black screen? if it is a black screen, the video output from the VCR is possibly faulty, this is not economical to repair. If it is just snow, and there is slight evidence of a playback picture from your tapes, try cleaning the video heads with a head cleaning cassette (available from eBay and electronics stores as a discontinued stock item).

Since Hi-Fi VCRs have the left and right stereo track on their head drums, and this drum becomes worn or dirty, the sound deteriorates along with the picture - mono sound usually with lots of snow.

This is a combo unit - it has a VCR/DVD common output section on the rear - allowing DVD and VCR pictures to be viewed when the respective drive is selected. When you checked your input connection, did you check the rear of the unit? you may have connected 'DVD priority out' instead of the VCR/DVD common out. If you did connect the common out, and still have no VCR picture, try the head cleaning suggestion as above. If that fails, consider replacing the unit as a last resort.

I am offering this suggestion 'gratis' - free of charge.

I'm getting nothing but snow when I press play on my VCR. Everything is plugged in, the sound comes through clearly but no picture. Any ideas?


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.

Movie tapes have snow but not home video tapes can i fix it my self


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.

Go video VR4940 VCR video recording has sound but no picture


You can try cleaning the video tape heads. The vcr has 2 different heads. One for audio which is fixed and a drum head for video with 2 heads on it that rotate. The best way to clean them is to take a lint free cloth ad wrap it tightly around your finger. Put some alcohol on the cloth and place it on the drum. Then rotate the drum as you hold your finger against the drum. DO NOT move your finger up and down as you can brake the head off. The other option is to go buy a head cleaning stick. It's a piece of chamie on a plastic tongue depressor. I've cleaned hundreds of them with my finger though. You can clean the whole tape path with the rag. Good Luck.

TV Snow and Static Sound


Sound like its all cabled wrong So its from the source, (wall satalight Whatever ) to VCR in then VCR out to TV, Now when the VCR fires up it tunes the RF output to Chanel 4 and has a strong signal, that over rides just about every thing. Simply way to stop this is one of two ways, press the TV/VCR button on the VCR, or simply turn off the VCR to let the signal pass through.

Tv monitor turns blue during forward or reverse vcr search


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.
