Re: picture is snowy and isn't clear

If you are using the RF out to connect to the VCR to your TV, perhaps the connecting Cable is faulty? And if you are connecting the VCR using the Audio Out / Video Out Cables, try replacing only the Video Out cable. In 95% of the cases, it is only the connecting cables which go faulty. If the above solution does not solve the problem, then we consider options. How old is the machine? if it is more than 5-6 years old, you need to get a service done. For chewing of tapes, 99% of the time it is a bad Pinch Roller(it is big (approx. 1 inch high. on the right side of the mechanism assy.)replace, and your chewing problem will go away.

Snowy picture

Clean the video heads. You can get a head cleaning tape. But the best solution is to take the top cover off and spray the Video Head with Servisol Video 40. Use cotton buds to clean any bad dirt off. Clean all the surfaces the tape touches. Allow to dry before putting a tape in. You might have to do it more than once. It will also take longer to clean if someone in the house is a smoker.

You need to clean the video head. Though you can buy a tape head cleaner tape, it's much better to take the top cover off and spray the head with Servisol Video 40. Make certain it's dry before putting a tape in.

I have a couple VHS-C tapes that drag

This may be caused by a faulty adapter. 1. try playing in the camera. 2. try a different tape. 3. try a different adapter.99% this is a problem with the adapter or the tape. It really sounds like the tape isn't turning freely, which can be caused by a brake sticking, or spindle in the tape or adapter.

Our Hitachi MX818E VCR is suddenly not playing videos. We can hear the sound however. We do not have the user manual anymore. Thank you, Ann

a common problem is rental videos that have been damaged in the first few feet of the tape by some other vcr's defective drive mechanism that "eats"the tape..What happens is the particles of the damaged tape clog the video heads in your machine,which have gaps in the millionths of an inch.Put a brand new tape in the machine and let it play for a half hour or so and it will usually clear itself.If that does not do it,insert a head clening tape and a couple drops of cleaning fluid and run it through.The newer machines will show a blue screen if there is no video information present.However,if you put it on forward search,it overrides that feature and you will see a snowy picture from a good tape,if one video head is clogged and the other is working.There are 2 video heads on a rotating spins at 1800rpm and that is the whirring sound you hear when play is pressed.If both heads are clogged,you will see a snowy screen and no picture at all.A 4 head machine has 2 heads for slp or 2 hour speed and the other 2 heads are used for lp and slp.A hifi vcr has 2 more heads,which are used for the hifi audio,a total of 6 heads.The stationary playback head has a control signal for tape speed,and regular audio,mono or stereo.

I have a Sony VCR. Model SLV-N51. I record a lot of television shows on new Sony VHS tapes and when I play back the tape the picture scrambles every so often. When I rewind it back to where the...

First of all I want you to check the tape inside it's case as soon as the problem occurs. Stop it and eject. You'll find a button on the side of the VHS tape, press it and you should be able to lift the flap. Look at the tape it should be smooth and shiny. If it is there's nothing causing damage. If you see any damage then the mechnism is causing it.
If that is good (which I think it will be) I want you to take off the top cover of the VCR and with some Servisol Video 40 spray, blast all the surfaces that the tape comes into contact with. You can wipe them too with cotton buds. Give the heads special attention. Once done leave for 30 mins and try it out.
I think the problem might be dirt that the head cleaner tape couldn't shift. The sound dipping being the hi-fi sound dropping out reverting back to the mono sound head. When you rewind the video tape acts like a cloth for an instance, hence the better performance.

LG RC195 dvd/vhs combo

Do you just get a snowy screen when you playback? I think the first thing to try is to clean the video heads. Either try a head cleaning tape, but these are not always the best thing, better still is to remove the lid & carefully using a head cleaning fluid (isopropal alcohol) & a thin piece of card or head cleaning stick (NOT a cloth), carefully & gently wipe the heads which are on the round silver drum. Do not use too much pressure or you will damage the heads, give it time to dry (couple of minutes) & then try playback.

Sound but no picture

first you will need to take a tooth pic and lightly clean the creases in the head , then use a cotton tip with cleaning fluid on it and wipe the head down , then if it gets to where you can see it again you may also have to adjust the tape pull pins for the tracking
if those don't work then the head is bad or there is a bad component

Very snowy picture when recording or watching video tape

If there is snow from the VCR only when the tape is being played, it is possible that there is a head clog or dirt on the heads.

If the head is clean and there is still snow from it, this means that most likely it is faulty.

A service tech who is experienced at servicing VCR's can connect a scope to the pre-amp test points, and run his calibration tape. With this he should be able to look at the signal carrier envelops on the scope and see if there are any faults.

At the same time, he will also see if there is a fault with the head pre-amp area. I've rarely seen any faults in the pre-amp area.

An experienced tech who works on VCR's can change the head for you. This is time consuming because he will have to go through all the guide and tracking alignments with the scope and test tapes.

A problem with most VCR models, unless it is a high end industrial model, most manufactures are no longer supplying replacement parts. They are telling the people to buy a new machine.

In reality, it may not be cost effective to service your VCR. You may end up buying a new one.

Beta VCR

Get all the belts changed in it and the pinch roller replaced. All of those decks had real rubber belts plus the lubricants where made from animal fat. It's a wonder it does anything at all but beta is great its the foundation of HDcam and the SR series today and what a beautiful picture.

No picture

This type of problem may be caused by a dirty video head, people some time try to adjust tracking to take care of this problem this is a mistake. Now to clear up this issue first you put the tracking control mid way in its setting, then you clean the heads of the VCR you can use a head cleaning tape (follow the instructions on the cleaning tape box)for this or if you have experience you use a chamois swab type cleaner (follow the instructions on the package of swabs and liquid cleaner). one the heads are cleaned you acn then try to adjust track to obtain the best picture. If you can not you may have video head problems or a problem in the drum motor (servo) mechanism. In which case I advise taking the unit to a TV repair shop.
