Toshiba Beta (Betamax) V5470B repair part 1. A very rare machine, but is it a load of old Tosh? video99.co.uk 2019-10-26 | Repair of a Toshiba V5470B (Beta / Betamax format). Part 1 of 2. Let's see if we can get a picture from a video recorder which is almost 40 years old. Working examples of this model are now very rare. It uses a mechanical type deck with lots of drive belts and pulleys. Probably the first video recorder to use an LCD clock, which was always an unusual display choice.Part 2: youtube.com/watch?v=nn90ZqdwrEsAudio and video transfers: video99.co.ukPlease support us on Patreon patreon.com/video99coukor Paypal to colin@video99.co.ukMusic “Let It Run” with permission, copyright Cristie/MacFarlane.See a demonstration tape for this machine: youtube.com/watch?v=2nOnCkcYtFk

JVC HDV on Panasonic DVCPRO-HD? video99.co.uk 2024-07-24 | JVC did a rare High Definition on miniDV format, HD 720P. But Panasonic's DVCPRO-HD machines supported the same resolution and could take the same size tape. As JVC and Panasonic were closely related at the time, just maybe the Panasonic will play the rare JVC format. Let's try it.
JVC invented a rare and little known professional video cassette format. HDV 720P ProHD. video99.co.uk 2024-07-19 | The miniDV and DV cassette format was sometimes also used for high definition. Sony created reasonably popular HDV equipment utilising 1080i or 1080p resolutions. But JVC had to do things their own sweet way, and made a few cameras and even fewer video recorders which recorded in the 720p resolution. Interoperability between the JVC and Sony formats was almost non-existent, making it very hard to recover JVC 720p recordings properly today. We look at a JVC GY-HD201 broadcast camcorder and a matching JVC BR-HD50 "ProHD" video recorder. We will try to repair both units. We will also look at the interoperability issue that comes about when attempting to digitise tapes of this rare format.Audio and video transfers: video99.co.ukOLD-VTRs user group: groups.io/g/OldVTRSAmazon Affiliate links for the microphone and wind chime, please use this if ordering one, it really helps us:Microphone: amzn.to/3zMMiv3Wind chime: amzn.to/41GarNxYealmpton Show: yealmptonshow.co.ukPlease support us on Patreon patreon.com/video99coukor Paypal to colin@video99.co.ukPatreon members often get to view videos early.Music “Let It Run” with permission, copyright Cristie/MacFarlane.Sorry I do not offer an audio or video equipment repair service.00:00 Introduction 06:44 Camera has a fault, try to fix20:56 Connecting and using the camcorder23:31 The video recorder, oh dear.33:24 Camcorders and microphones39:47 A format of one machine?

The unobtainable connector for U-matic dub cables. Hirose plugs and sockets. video99.co.uk 2024-06-14 | Professional U-matic video equipment gives vastly better performance when connected to a Digital Timebase Corrector with the proper Dub cables. But here in the UK, it seems to be impossible to buy either the cables or even the Hirose RM12BPE-7S(71) type socket connectors to make them up. The RM12BPE-7PH(71) plug however is still obtainable, and the chassis mount sockets are just about obtainable, or could be scrapped from old machines. So could we make the required super-rare connector by swapping parts over with what we can still obtain? It wouldn't be easy.I am absolutely not offering to make these up, but you could get some good pointers on how to do it yourself. More information has come to light about pins 3 and 4. They could potentially carry and R-Y signal and the ground side is Pin 4.Here's where we finish the cable build: youtube.com/shorts/2uKEY543084Audio and video transfers: video99.co.ukPlease support us on Patreon patreon.com/video99coukor Paypal to colin@video99.co.ukPatreon members often get to view videos early.Music “Let It Run” with permission, copyright Cristie/MacFarlane.Sorry I do not offer an audio or video equipment repair service.00:00 Introduction 03:36 What do we have?06:48 This may be possible09:35 Try pressing out the socket14:30 First success15:19 Sacrificial plug18:29 Press out plug20:37 Press in socket25:19 Result and a small oops30:02 Wiring considerations34:31 Conclusion

Skiing tapes clog video heads video99.co.uk 2024-05-16 | The only subject matter of recording which seems to cause a problem is skiing. The cold temperatures caused camcorders (miniDV in this case) to contaminate the tapes which can cause problems at playback time, years later.
Sony Betamax SL-C9 video recorders. Can we get something working from these? Part 1. video99.co.uk 2024-05-10 | The SL-C9 is a highly sought after Beta video recorder. What it lacks in hifi sound, it makes up for in slow motion functions by use of an extra playback head. They are also very useful for connection to PCM digital audio encoders. But they are not the most reliable of machines, suffering a myriad of mechanical and electrical issues.

A seriously expensive bit of kit. A few weeks ago we tried really hard to repair this monitor despite it being designed to be unfixable with very limited service manuals.

Sony EVS1000E Hi8 recorder from 1989. Can we fix it? video99.co.uk 2024-04-12 | In its day, this was a very high end Hi8 video recorder which includes PCM digital audio capability. This one has broken down, let's see if we can find out what is wrong and get it going again. Bear in mind that new spare parts are unobtainable, and we only have fairly low resolution service manuals. It uses the Sony U-mechanism deck.

KAIWEETS KTI W01 Thermal imaging camera includes visible optical view too. video99.co.uk 2024-03-22 | Now there's a thermal imaging camera which also includes visible optical camera at the price of a one without the optical view. Visible / thermal blending can really help in many applications. With good specifications, a removable battery, variable mix of visible and optical both on camera and in software, this looks promising. We test it on electronic, automotive, soldering, hot and cold samples. We also compare some of the captured images directly with those from a competing Topdon model.Audio and video transfers: video99.co.ukPlease support us on Patreon patreon.com/video99coukor Paypal to colin@video99.co.ukPatreon members often get to view videos early.Music “Let It Run” with permission, copyright Cristie/MacFarlane.Sorry I do not offer an audio or video equipment repair service.DISCOUNT codes:10% off code: VQB4UO2S$30 coupon: Apply on product page(Save 10% plus $30 in total)Date of expiry: 2024-5-31Buy from Amazon.com: amazon.com/dp/B0CB7Q6J7915% off code: CM15(Available sitewide at Kaiweets.com and it never expires.)Buy from official website: kaiweets.com/products/kti-w01Below are a list of possible improvements, some of which may be implemented in updates by Kaiweets.FIRMWARE:1: OVER needs to say UNDER when off the bottom of the range. This could potentially be a safety issue so it's really important.2: The red text for the hottest point is very hard to see and needs to be changed a little to make it more visible.3: When using the menus, the ENTER button has to be pressed to go into a menu selection, but the RIGHT ARROW should also function to select a menu item. (Also, to back up out of a menu, the LEFT ARROW should work as well as the back up button.4: Going into the temperature range selection needs to be promoted to a higher level function, not buried in the settings menu.5: The unit is difficult to use when trying to measure something around 120C because it keeps displaying OVER. There needs to be an overlap between the two ranges, or even a third middle range added.6: Consider adding alarms and make that audible. Also if it could trigger an alarm on a connected PC, that could be very useful in industrial applications.PC SOFTWARE:1: It should be possible to re-align optical and thermal images in the software, in case the alignment was not set properly during the image capture.As regards HARDWARE, I would suggest the following updates on a future model:1: Add tripod mount, or even two to also allow sideways mounting. 2: Add a switch to detect the cover is down and signal this on the display.3: Try to get the optical and thermal lenses closer together to reduce alignment problems, especially when having to work with nearby objects which are moving around.4: Add a small finger grip to the bottom of the cover so it is easier to find and open when required.00:00 Introduction 00:33 Look at unit05:43 Connect to PC08:22 Hot PCB testing14:09 Optical / thermal align17:35 PC software21:29 Test around 120C24:38 Hillman Avenger heated rear window27:27 Excessively hot soldering iron28:02 Boot time race29:50 Compare to Topdon39:09 Conclusion
