Hi Noel.

Thanks for getting back to me.I am interested in the video heads for the HF150 and also the front flap.How much for the both items.

I am delighted you can provide both items as the unit is in mint condition and is well worth repairing.Not sure of your email address.I am at [email protected]

Many thanks.

Gary.

PS am I right in what I am saying that the heads for the 150 fit the 100.

Many thanks again.

Gary,

I can assist you with new Sony SLHF150 video heads and also the front flap if you cant source either of them locally in the UK.

Send me an email if you wish to follow up.

Many thanks.

Gary.

Hi all, I need to replace the CV001 cap. trimmer on my SL-HF100, but still can't find any suitable one on the web. Could you kindly advise? Thanks!!!

For general information,

I managed to source quantities of at least 10 each of the ICP-Nxx series fast acting semi conductor fuses I mentioned in a post below, except for the lowest rated ICP-N5. (Two ICP-N5s are used in the SLHF950s)

Sorry for the delay - I have been busy with family stuff. Sending photos of manual pages I think you need today.

Regarding my questions below.

These have been withdrawn from sale by the original supplier. (no longer available)

However, I eventually found some quantities on eBay or the N15, N20 and N25 from three different sources from China to Hong/kong.

Hello all,

A general question, where can I get supplies of the N series of electronic fuses used in the Sony VCRs.

I have found a UK source on eBay for N25 but not much else.

The sony models use N5, N10, N15, N20 and N25.

BaiBa2,

I have a service manual for the HF150 plus replacements for the IC that is used in the HF150.

You can email me by dropping the "nospam" from my email address or contact me through my website at Betaheaven.com and I will email you photos of the circuit and power supply check information.

regards Noel

Ba1Ba2:

These are non UK machines so unfortunately I cannot help with the manuals.

The STK IC's in Sony's can cause erratic non functions such as those you mentioned if they have gone bad. Similar situations arise in the Sanyo's models with those in the PSU.

There are some overseas users who occasionally post here who more than likely could help you out.

It's just a matter of when they see this post.

Good luck...............Kevin

hello everybody from Italy, this is first time i wrote on this site but i follow you

from a lot of time. Just to introduce myself i have bought a Sanyo Vtc-5500p in 1981

with which I recorded all football matchs of Italy Champions of the world of the Spain Mundial in 1982.

It's a great machine with high video registration quality. I've seen that there is no page for

this machine. If required i can post the photo of the recorder.

Now i need help for another machine, the Sony sl-hf150 that goin on but

only Av on the display and no green led. There is a problem with power supply

and the stk5443 is cold.

Can someone help me with the service manual of this machine? Many thanks.

Hi Noel:

I appreciate your comments and input as always.

Rest assured on ANY Sony I work on the reel drive area is always stripped down and both spools lightly oiled and ,yes, that wear to the plastic bearing area always checked (by the space between the flywheel and coils).

Also the capstan speed remained constant ,it was just the forward direction reel that sped up after it got warm. Resulting in tape damage in certain modes.

I now have a replacement board fitted and all issues gone. It's been way too long for this one.

I have another of the same (SS28) where there is no reel drive at all. All other areas OK.

Thanks again for your input and also to Clive for the deal for this 100% working one.

...............Kev

Stephen:

Whilst I've not come across that exactly I have seen one where someone had replaced the entire drum assembly from an early VTC 5000 and the head activation was a tad too slow when pressing PLAY. The result being a slight delay in picture pick up at the start. This and other parameters are not compatible with the NX100. The same as a 'M' series capstan will not work either and the pinch roller that later model is a tad smaller than on other earlier ones too.I have also seen a few NX100 's with worn heads. Which is normally not an issue with Sanyo models.

If the Reel motor is noisy too then obviously it's a high mileage machine.

One way to tell on that model if it's seen high use is, look at the two raised strips on the cassette hatch flap at the bottom. If a lot of the black paint is worn off it's seen a lot of use.

AS for your original issue. I would check the caps in the PSU. Also make sure the head drum bearings are not too tight or have been fiddled with in order to quieten them down instead of lubing them.

Hi, I was wondering if anyone could help me with a Sanyo VTC-NX100?

All functions seem to work, but when Play is engaged, the tape laces but the drum is slow to pick up speed. The microprocessor then locks up, requiring the mains power to be cycled. I've seen this on two of these now, and was wondering if anyone has seen similar. Regards.

Kevin,

Your email prompted me to remember that the reel motors on the front load Sonys can all suffer the sort of problems documented on the SLHF950 chassis repair information.

The spindle pivot for the magnetic shaft wears and the magnet eventually closes the gap to the winding and then runs the insulation off and spreads copper between adjacent winding shorting out the particular coil.

You mentioned that you think its the control board but that might only be the symptom caused by the increased motor drive current requirements.

Back to what you said - It speeds up when it gets warm - but that does not happen with the above condition. The capstan motor keeps the speed constant so you should only be noticing and increase in forward tension, not the machine speeding up.

I spent hours fixing such a fault once and it was due to a leaking transistor which tested OK but failed intermittently in operation due to heat related excessive Icbe current.

Use some coolant spray on the transistors in that part of the control circuit to track down which one if that is what the cause is.

BUT REALLY - neither explains exactly why reduction in forward tension (a reel function) allows the speed of the capstan to reduce. Are you sure the capstan roller is holding the tape hard against the capstan shaft?

SOME FOOD FOR THOUGHT!

regards Noel
