HOW TO CLEAN VHS VCR HEADS

Vcr's commonly get dirty heads that cause a blue or snowy screen and no sound in some cases. In my experience the rental tapes were common point of trouble especially when you consider the amount of machines that were deployed in use back in those days. Today people run into less issues because they have there own collection and put them to good use. In order to deal with some people's problems there are three approaches to cleaning heads, the first option is to use a wet tape with the provided fluid usually two or three drops will do and run it for ten to twenty seconds. The second approach is use a dry tape with same amount of time as outlined above. The third approach is get a blank store bought tape "T120 2hours" set the vcr to sp and run the tape from beginning to end, this is a good way if you want do more of a deep clean to remove difficult dirty particles that refuse give way. I find the dry tape will give less problems when cleaning and less chance of shredding and easier for people who don't like taking vcr's apart.

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 location. Is the vcr picture part internally broken? if so I will have to buy a new machine. If all you will say is yes I dont want to pay 12.00. That does not fix the problem if unfixable. thanks sherry.


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.

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 head.it 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.

Video image problem- Blue screen?


If your unit is fairly new,your VCR part might be the problem.Take it back!
If you have this unit for awhile,two things:
1. You need a professional A/V repair guy to clean up and check your VCR head.
2. The rental VHS tape is dirty.
Good luck!
