Intermitant sound on playback. I have manually cleaned audio heads which did improve audio, Machine initally did report "use head cleaner"

Hi Graham92. Read this through a couple of times, sorry it's a bit long-winded.

This may sound a bit strange but the Video Heads on the drum may be causing the sound to cut in and out. The reason for this is the audio circuit requires a clean signal, (good constant picture) from the Video drum heads. Most VCR's have an audio mute when a bad bit of tape passes through the mechanism to stop loud noises from passing to your speakers, TV, Hi-Fi etc. It sounds like you have taken the unit apart before so i suggest cleaning the rotating video head.

Unplug the VCR, locate the heads, usually under a metal lid. The drum is titled on a slant and has 2 heads-VHS or 4 heads-S-VHS which are visibe as a small horizontal slot, (3 mm approx) on the side of the drum. The way i suggest to clean these heads is to use a piece of flat, thin card about the size of a postage stamp, and some cleaning solution (alcohol based). Apply a little solution to one side of the flat card and apply the flat of the card with your finger to the side of the drum with light pressure. Do not press hard as this will break the pick-up coil on the head. Rotate the drum, as you do this you should be able to feel the heads through the card to your finger, this is good. Continue to rotate the drum for 5 complete revolutions. Inspect the card for any sign of dirt. Repeat proceedure if neccessary until no sign of dirt remains. Reassemble unit and test with a new pre-recorded cassette. If all goes well, test with the Cassette that you noticed the sound fault with, ensuring that this cassette is in good condition. Hope this helps you out. Post your resutls back and good luck.

My Panasonic NV-SD250 VCR displays FO4 message. The unit refuses to eject tapes.

Possible fault with the failure of the servo system, the mechanism , front loading and forward loading or the failure of the drum servo/capstan servo.
You can remove the front panel and top panel and remove up the loading mechanism by unscrewing the mounting. carefully disconnect the cylinder head strips, the audio connections and remove. manually turn to unload off the tape. then check for belt failure or visible errors. Now set back use a dummy cap to cover the end sensor emitter at the centre and manually push the loading mechanism assisting . If there is no loading the capstan is faulty, if it loads and the drums does not work it is tthe cylinder servo.
You will need some knowledge of the circuits to proceed to the correct fault.

How much is it worth used?

Hi there,

I can't give you a definative answer for your particular Sony DSR-11DV as the second hand price for one of these is going to depend on a few area's: the overall condition, that it functions correctly, it has it's accessories (leads, remote etc) and also how many drum & tape hours the machine is showing. Looking at ebay as a reference point for a general price in pounds sterling it looks like:

Used, working, below average condition, showing damage, around £260
Used, good condition with around 200 drum hours around £320
Used, working, below average condition with 20 drum hours £370
Used, good condition (accessories inc) with 31 drum hours £525

As I stated above the price can vary considerably, also the market can change and subsequently prices can fluctuate. These prices were obtained from finished auctions on ebay in April 2010.

Hope this helps,

Sanyo vcr player vwm 900, tape won't COME OUT.

This needs a little bit of care but essentially you will need to unplug the power from the VCR then do the following:

Remove the top cover
Then with the front of the VCR facing you look to see if any of the tape is wound around a large metallic silver drum, that is tilted upward and is not flat, at the rear of the tape casing. If so then it means that it has wound around the drum and you will need to retrieve the tape to allow the eject mechanism to work. Do not touch the shiny polished part of the drum. To get the tape in usually means that you have to locate a plastic or metal cog wheel, usually on the right side of the VCR that you can turn with your finger. This makes the VCR motor move. Also there is one that works the tape eject mechanism. If you can find the one to wind in the tape before working on the one for the tape eject than you stand a chance of rescuing the tape, if not then it will get some damage. Don’t worry about turning the cog wheels with your finger as you can do very little harm to the VCR with no tools involved and no power on. Moving the cogs this way will only cause very small movements with the tape motor and eject so you will need to be a little patient and you will soon see what is happening. Once remove run a cleaning tape through the VCR before you use it again. With the limited space available her it is difficult to give you much more info.

Pictures not showing(VCR)

There are 3 options that I can think of, 1 is that one of the heads on the upper drum is damaged, can see this if you look closely at each head, there should be no corners missing, it should look square, 2 is that the heads are dirty, cleaning tapes are really not that effective, if you wish to try this at your risk wet the back of a clean white business card (that has no images or writing) with ethanol or clean alchohol, place the card with the centre of the card between the lower and upper drum and carefully and slowly turn the drum clockwise by hand so that each head rubs the centre of the clean side of the card, repeat this until no more marks show.(do this only if you understand my explanation and at your own risk) 3 that one of the cables you have disconnected has not been properly seated or that the cable is damaged, check the ribbon cable connected to the head amp (silver box either lhs or rhs behind the upper drum). hope that helps.......Phil

Can hear crackling or spitting sound when selecting HI-FI

The "crackling" sound you describe sounds suspiciously like mis-tracking. That is: The result of the Hi-Fi heads (which are on the rotating video headwheel or drum) not exactly following the recorded tracks. Have you tried adjusting the tracking slightly? The reason this happens is that the Hi-Fi tracks are MUCH narrower than the thinnest video track (used for 6 hours per T120 tape). Tape stretches and shrinks as it ages. Video recorders wear with normal use in such a way that the tracking changes. The problem is often worse with tapes recorded at the SLP (6 hour) speed because the servo cannot correct errors as fast when the tape is moving slowly (on some machines only). Tape quality also counts...and manufacturers change their formulations without public notice. All these things can lead to "archived" tapes being lost. Solution: Use the best quality tape you can afford, not the cheapest; record at the highest possible speed. Store the tape carefully. Never use a cheap "rewinder" because they can over-tighten the tape causing wrinkles, stretches, and other kinds of damage.
