Sony SLHF1000 Betamax No Video component level repair 

Amazing to see those old machines come back from the dead. Just love it.

Hey man. I've praised you before, you know this and you deserve it. There are 2 types of people I think that watch all your videos, myself included. The first kind are the vintage hifi buffs and the second are hifi buffs who have learned alot about different aspects of repair from you. I wonder if you have a video or would make a video for us who are the hifi fans and electronics hobbyists showing what minimum gear we should have if we wanted to fix an old av device that we picked up at valuvillage or the usual haunts. You are a master of your craft and as such can do more with far less gear with a lifetime of know how than us eager to learn. Your esr meter, dmm, dso while great pieces of kit are not available anymore. Especially your esr meter and fluke. I've searched for the same esr meter you have and cannot find one but I found and ordered one similar to yours, which at regular price here in Canada is about 150. I ordered mine from China to save 110 dollars. I guess what I'm trying to say is would you mind making a video with a basic outline of the gear you use and more importantly where should we start as beginners. I have a pretty good set of tools and such but we both know tools don't mean sheet without the skills to use them. I'm a little farther along than a complete beginner but by no means consider myself competent to fix another person's device. I've changed hdmi ports and fixed traces here and there on game consoles but I have a vintage Roland digital effects pedal board from 89 that I wouldn't dare mess with yet. If you've made this type of video I apologize. If I come across any old belts or motors I think you'd be interested in I would be more than happy to send them. I plan to join your patreon regardless if you make the video or not. The wife is on me for an 80 dollar a month patreon bill, I support or make a donation to anyone I learn from. Great video by the way and congrats on the silver button.

I love this channel. It's to the point and shows everything.

Video loaded with a lot of new information that I could use in my shop. thanks for sharing.

I still own a Sony SLHF 1000 in near mint condition. I once thought about selling it at one time, but I think I'm going to hold on to it now.

Great job Dave, people can't resist fiddling with things. They think there going to save themselves some money, but little do they know they're increasing the bill with the extra work the technician has to do.

I got this..., we'll turn this screw and this one and maybe this one....! Well I can't figure what I did wrong..., well let's give it Dave! Many hours later after being screwed driver to death... Dave got it running like new again!!!! As always another great video!

Brilliant repair ⭐⭐⭐⭐⭐

excellent video, thank you

DAVE, Nice video. I agree these machines are built like tanks, well made and serviceable. I hope you charge accordingly knowing that not too many people can properly service vintage electronics.

Amazing work Sir.... Love you from Pakistan

Long ago I came across a Japanese webpage detailing how to rebuild those STK modules. I didn't think to save or bookmark it though. Sony puts out good manuals and actually labels the bottom of their PCBs. Unlike the Marantz SR940 receiver I've been working on that has zero markings on the bottom side of the PCB and a black and white paper service manual with zero indication of signal and power routing (grounds have bolded lines, that's it). At least its easy to access the boards although way too many cables are soldered on as opposed to using plugs. Regarding service manual scans, its due to people either not knowing what they are doing or not giving a crap. I had to scan the Marantz manual because the print was too damned small (a lot easier to zoom and print segments of pages). Landed up using a borrowed large format scanner at 1200dpi for excellent results. The fold out schematic pages were scanned in pieces and auto stitched together in Photoshop creating one seamless large page. I also OCRed the whole thing, makes it easy to reference the parts pages with a simple text search.

And this time, the problem with no video is not because the black video switch is on. Nice work, man. Sucks that you had to also fix an unrelated problem because someone thought they could adjust the original problem away.

Amazing video. I wish I had this level of knowledge. I may have yo watch more of your videos. I got a betamax sl-100 I'm going to try and tinker with.

Thx for making these video's

Wow, I have three of them. It really a work horse.

Good repair ♥️

This is the sort of long video I like to go to bed and sleep to.

Isn't the 3KHz test tone used for checking wow & flutter, and the 5-6KHz tone used for adjusting the azimuth of the A/C head to bring the treble to its maximum possible level?

Epic. Keep it up...

Ah, the good old golden screwdriver technique, customer turns all the pots because the screws must be loose. I always liked the Sony machines, no longer have mine but still have a Sanyo Beta machine

It is definitely bad when you have to correct an additional fault that someone introduced that otherwise didn't exist. About the resolution: if I recall, the specs for PAL are 260 lines in colour and 300 lines in b&w (on VHS 240 lines in colour and 260 lines in b&w).

thats amazing

I had also an open coil on my philips crt tv-set at the nec of the tube and no picture.

When I used Betamax equip. for several years. Some information sources claimed that any Beta unit will work with any other Beta unit was not quite correct. I had a Zenith 'portable' recorder and a Sony video camera (HVC 2200) a nice camera except that it needed a lot of light for a great picture. Anyhow, when in the recording mode, hitting the pause segment, the recorder went into pause. When releasing the pause, the recorder would go into fast forward ( in the recording mode). The local tech looked at several times and could never get it to do this crazy action. So, in order to start and pause in the middle of saving a video moment, I had to hit stop and then go back in record mode.

These are nice machines. What's your opinion on the ED beta machines?

The Beta doctor at work 👍

Hello bro good video I like

Cool! Thanks for the upload! Do you have any skills at Video 2000 systems? It would be cool to se some repair video of that system!

I like it when E-E doesn't work, rather than just off-tape. Signal tracing is much easier when you can just stuff a known good signal in and see where it vanishes. But without schematics, it would have been almost impossible. Alas nothing like this machine was sold in the UK.

What's that lamp you use for your desk lamp please? Is it a halogen? Iv noticed that it's nice and small and easy to manipulate the position, is that something you set up yourself?

It's interesting to know why the inductor on this part of video chain, are blow up. Amazing video however.

Can those alignment tapes be copied? Super video as usual!

Super.

Dave! I have one of these machines, and the head drum won't spin. I have the service manual and have repaired VTRs before, just not sure where to begin on this unit. Do you have any idea, why the head drum won't spin the rest of the unit, appears to function normally?

Hi Dave, I just had a good deal from a client. "Archive my 12 tapes and you can keep my HDR-HC1E" Only problem it frequently pops up the C:31:22 error and battling to do a proper capture. How can I fix that? Looks like a rather professional machine.

Have you worked on sony slv 575uc. I have one that has issue with video. The TV does not display anything on screen but typical blue screen. I am able to hear the vhs recording. I believe it has to do with the RCA video output port. How can I check that with any voltmeter?

Hi am just thankful for your videos just good work,you magic idea tell me how you do it

Without that diagram, it would have been horrible. I agree with the crappy schematics on the net, if you can't read it, it's pointless. I was supprised it was a choke problem, i've not seen many go o.c.

Sir I need Sony Slv-x715sg modal chazis can you provide me.

What causes that to burn out like that? Old age or a surge maybe!

I have 2 EDV 9000 from japan i use them to convert my PAL tapes to ntsc using a converter here in Australia one of edv has low distorted sound in line 1ans power supply issues currently getting repaired ntsc beta seem to be cheaper than the PAL ones

Where does everyone get their schematics. Ive found some things for old arcades but not much on old players. Id even pay for them if i could find a spot.

On the KR5-1V you have only the color pattern with AFM audio in βII. On the KR5-1M you have only the color pattern with AFM audio in βIII.

29:00 servo vaporwave remix.

You must have an arsenal. Right?

Yeh but it's a beta try and get tapes for it still good video

SP = Superior Performance, not Superior Picture, but I'll give you a pass on that. Close enough 😜

VCR repairs are 2 fold. Electrical and physical. 😑

To many commercials... sorry my friend...
