I have a Sony DVW 790wsp Digi Beta Camera. The front glass in front of the CCD is misty/stained and I am looking to find a replacement part.

I think the part no. is 82011 or B2011.

You see it when you look down the lens port.

Can anyone help?

Has anybody got a set of PCB service extenders for the Sony UVW-1800P.

The TBC has failed with no B-Y and low Y signals.

It failed because the SMPU voltage had gone up on the +5v Rail to 8 volts.

The pot on the side of SMPU set it back to 5volts but the damage has been done!

cant see how youfault find without them.

I have over 100 master copies of adult films in the betacam format. They were produced in the early 2000's by Markman Productions and were shown on Showtime, Cinemax, and HBO. I also have 35mm negatives of various scenes from the movies and the movie scripts. These were given to me by Markman Productions for work I performed. Anyone interested in buying contact me with an offer.

Hi. Few days ago I've got used BVW-35P from ebay. It have some missing screws. But the more important problem is that it doesn't anything when i press "eject", any other mode buttons, or cassette presence switch. But timecode controls works fine. 9 pin control also not working. I disassembled it, and it looks pretty good. I haven't noticed any damage like missing parts, leaked caps, burned parts, etc. Also i was unable to find part 2 of it maintenance manual. Can anyone please help me with repair of this machine. Thanks!

Just to let everyone know, Betacam PALsite has just been fully updated to work better on mobile devices

Other thing is put a colour bars tape and connect a oscilloscope in Y, B-Y and R-Y ouputs for see what output is wrong

I have a Sony UVW-1800P and the B-Y and R-Y outputs works but Y output don't works

I checked with the oscilloscope and Y arrived to the input of last A-D D-A (CTDM)

I have bad the last A-D D-A (CTDM) converter of Y

This is a common problem?

This vcr was struck in a car travel of 650 Km in Spain (the friend of the seller drove badly), when I receive works very good but in 3 months after appeared this problem

I will see again, has all in IC'S SMD

Phil Winfield you need a oscilloscope for check if the signals Y, B-Y and R-Y arrived to the A/D D/A converter

The signals of the heads are in FM after is demodulated in this point a tape with colour bars should appear, if don't appear there is a problem in heads o FM demodulator

If appear the A/D D/A converter is bad

But E-E works, I go to search the schema and I will tell you

Please help has anyone lately had interaction with Martin Potter and do they have his contact details If you want to contact me to know why I am desperate to contact him I will be available on my e- Mail. Please help if you can , thanks , take care. Steve

Hi, I've exactly the same problem. I will try to do some measurements and will contact you if found something.

Hi David

Do you have any further advice for my problem?

Thanks

Phil if you put a signal in a input this appears in the outputs?

Checking the composite video, s-video and Y, B-Y, R-Y inputs and outputs.

I have now tried to put a composite signal into the machine and yes, I do see an ouput. Do you need me to confirm the same for all inputs and outputs?

Phil this is called E-E or electronic to electronic

For to be clear the inputs signals is changed to FM signals and changed again for to be a normal signal

This only appears in Betacam and U-matic vcrs but in VHS, Betamax and Video 2000 don't appears because is more expensive to put this circuit

I have not tried to see if an input into the machine produces an output - will try this and report back!

Phil if you put a signal in a input this appears in the outputs?

Checking the composite video, s-video and Y, B-Y, R-Y inputs and outputs

Hi, in answer to your questions about the Betacam VTR. Nothing on any video output. Heads have been properly cleaned (which was the first thing I tried). I tried another TBU board and the picture returned briefly until I once again was suffering firstly from picture blocking and then total failure.

Any further suggestions?

Thanks

Somebody sell a small Betacam oxide tape?

Phil Winfield

Do you check with other tapes?

Do you ckeck in all video ouputs?

I think that you video heads are dirty

Hi, I own quite a few old ex broadcast kit. My BVW-75P was playing a tape yesterday when the picture suddenly disappeared on the monitor. The TCR code still shows, sound is ok too, but no picture. The monitor does show that a PAL signal is present.

I have lifted and replaced all the cards I can see, but still nothing. Looking at the technical manual, perhaps the fault lies with one of the TBC cards, caps look ok on all the cards?

The picture was stable and no noticable issues before it disappeared.
