Sony SLV-N750 sound problem

Looks like a great brand with good features for the price.

1. Connect Video & Audio Cables to a video signal source
2. Connect Power Cable
3. Turn on VCR.
4. Insert a blank tape in the VCR.
5. Note - A Broken Tab on the back of tape will prevent recording. This is called Write Protection.
6. Cover the tab hole if you want to record over old video.
7. Press RECORD on the VCR remote control.
8. After a minute, press Stop, then PLAY to see recording.
9. Cheers

Check the audio/control head for damage and any conections to it. The audio head could also have failed.

Needs cleaning. You can either use headcleaner cassette ( not always effective ( If you can find the type with micro-filament brushes they're more expensive but far more effective and last forever ) ) ; or alternatively do it manually ( sometimes neccesary ) ; unplug unit, remove the cover and clean all the surfaces that the tape comes into contact with ( using Q-tips and head cleaning fluid ( most effective ( when done thoroughly ( have to keep at it until absolutely no trace of black carbon comes off on Q-tip ) ) ) .

As JSE suggested.
Also dump any very old tapes.
As you say some play perfectly, I suspect, from personal experience, that faulty ones are either very old, or if recorded on another machine, may be mismatched with your current player.

If this unit is 4-7 years old then TOSS it. As time goes by the rubber gets soft and the units timing gets whacked. Repair will be more than what it's worth , unless your emotionally attached to it ...

Please rate!

As long as your cable company converter box is feeding your VCR, you should be ok. The cable box should convert to analog which is what your VCR records.

Hi, i have a Panasonic dmr-es30veb DVD ram recorder/VCR and i cant record one channel while watching another, as you can tell i am not at all technically minded and if you can help i would be grateful many thanks Eileen.

It sounds like the taped program was recorded on a different speed. The other VCR that you are playing the taped program may not have the speed needed to play it correctly.
Next time when you record a program try to make sure you use a speed that will be compatible on both VCRs.
For example a tape that last 120 minutes, using the different speeds will give the following recording times.
SP means "Standard Play" >>>> 2 hours
LP means " Long Play" >>>>> 4 hours
ELP means " Extra Long Play" 8 hours

Older VCRs have all the 3 speeds but newer ones only have SP and ELP.
Hope this helps.

Is it ejecting the tape when you set up for timed record, or any record mode for that matter? If so, check for the presence of the record lockout tab in the tape. If tab is there, machine should accept it. If machine ejects tape with the tab present, then the sensor which detects tab present or absent is probably afoul. this sensor is often a small switch. This tab, by the way, is on the backside of the tape, on the left, looking at the tape from the back.
