Sony Betamax head drum sensor replacement

[@KarlHamilton]

Almost certainly never going to even own a Betamax machine, never mind repair one. Yet I'm strangely addicted to this channel. I think it's your passion that I find enthralling.

Shortcuts usually grease the rails to disappointing outcome. But this looks like a good one. 🙂👍

It's not just that it saves time, it's more about reducing risk of damage. It's so easy to smash the heads when removing the head drum assembly.

I have a similar problem on a Betacam SP recorder, there is no PG signal. I think something was happened with a sensor on a video drum.

[@video99couk]

Could be the same problem.

I also found out in this kind of repair 15 years ago. The glue contained salt. It's rude to the manufacturer, but it's almost a failure.❤❤❤❤👍

Dear Sir, When I press the play button on my SONY Betamax SL-C5 the Video Head Drum Assy's starts to spin (with and without video cassette) for about 60 seconds and stops. Do you think the problem is the hall sensor?

[@video99couk]

No, that's not the fault on a C5. There may be a servo or some other fault due to capacitor failure, or a mechanical fault. The C5 is not an easy machine to fix, it needs someone who is familiar with video technology.

Many thanks for your kind response. Sincerel

I thought about this when repairing the drum motor of my Betamax, but then decided to remove the board to check the tiny electrolytics it also has. They were all fine ESR-wise, but replaced them anyway because I have bad experience with those miniature electrolytics, SMD or not. I bought the sensor from a German seller on ebay.

[@video99couk]

There's something to be said for replacing those anyway.
