Panasonic S-VHS NV-FS200 no signal video from scart

[Nicola71]

Good morning everyone.
My name is Nicola, I write from Italy and I love old video recorders.
I recovered a Panasonic NV-FS200 which has a problem: connecting it to a TV with a scart socket on AV1, no video signal but audio present.
If I connect VCR to RF coaxial antenna, video signal is excellent in color, audio is also present.
If I connect to AV3 (S-video and rca audio), video signal present but in black and white, audio is ok.
How can I solve the problem? Thank you for your answers

The TV has a SCART connection?

obviously.

With SCART the composite pin is shared with the luma pin of s-video (s-video uses a second pin to send chroma, colors). A black and white picture usually means the two devices disagree on what's being sent on the luma pin, one is set to composite, the other to s-video. Go through the device settings on both and make sure they are both set to s-video.

Thanks for your reply Jagabo. The TV I connect to the Panasonic is a Loewe 32 '' Vitros 6381. To connect S-video from Tv to Panasonic I use a 21 pin Scart cable (AV1 TV) which ends with Panasonic S-Video OUT connector.
The problem for which I am writing is to understand why with coaxial RF connection, the image is present in color, but with scart connection the signal is absent. Audio is always present.

on the back of the VCR, did you try sliding the switch to normal position ?? - https://www.libble.eu/panasonic-nv-fs-200-eg/online-manual-487012/

Certainly. I tried both "normal" and "test Signal" but I got the same result.
If I videotape from the TV by connecting TV-VCR Scart AV1 and then play the cassette with another S-VHS VCR, you can see perfectly color video and perfect sound.

Do ensure that the scart lead you connect from the vcr to the tv is fully wired. Many only have some connections.


But if you are connecting the other s-vhs vcr to the tv with the same cable that is not the issue.

Hi, thanks for your reply. I have tried three scart cables which work great with other devices.

Scart to scart (in menu rgb instead of svhs) will have color. If you use svhs from vcr to tv (svhs in menu for av1/2)

Hi mammo, thanks for your reply

Scart to scart = no video signal
scart to s-video/rca = video b&n , audio ok

This unit does not have any on-screen settings menus: everything is controlled directly by switches and buttons on the front panel.

According to the instruction manual. it operates similarly to its American cousin the Panasonic AG1980, with minor differences like the addition of SCART connections. Apparently it is not necessary to choose a connection before you use it : the NV-FS200 is a semi-pro unit that keeps all output connections active simultaneously.

A proper 21-pin SCART to SCART cable should simply work without issue, as should a proper round-plug S-Video cable. If these same cables work OK when connecting your other VCR to the same TV, you may have a defect in your NV-FS200. Like the American AG1980 model, the NV-FS200 is known for eventual failures in its circuit boards, and the internal connections between the boards and external sockets. It is possible for the VCR to fail in such a way that direct video connections like SCART and S-Video become faulty while the RF connection remains normal. Try to test this NV-FS200 with a different TV and perhaps different SCART cable: if problems persist, the NV-FS200 needs to be serviced.

If it is a circuit problem he will not have picture on svhs also it looks to me like a composite svideo problem many vcrs that don't have svideo output and you connect svideo cable on scart you will get black and white picture.
You are right about the menu I was thinking of pann dvd recorder menu when i posted my mistake

Hi mammo, thanks for your reply

Scart to scart = no video signal
scart to s-video/rca = video b&n , audio ok

FS200 has svideo output on back also did you try svideo directly without the scart svideo conector

If I connect the TV with the VCR through a direct S-Video / S-Video cable (no scart) I have the image in black and white.
I think repairing panasonic vcr failures without owning entire replacement cards is impossible.
The tracks of the circuits are invisible and I don't know where to put my hands to begin to understand.
I hope to find an identical model with broken mechanics but with working electronics.
Thanks everyone for your kind responses.

This series of Panasonic has known issues with peculiar video circuit failures, as I mentioned. mammo1789 makes a good point about common composite/svhs issues leading to B/W svhs output with many VCRs, but since you are getting nothing whatsoever from the SCART output and B/W from the dedicated SVHS tap I would suspect typical aging faults in this NV-FS200.

The good news is you say it plays beautifully thru the RF connection: that is extremely important to whether this model VCR might be easily repaired or not. Normally, when they start failing the video is bad thru all outputs including RF (symptoms like faded color, B/W playback only, color stripes, interference patterns, etc). Those issues indicate serious electronic decay of the video boards: repairable only by a few specialist technicians (but such service is very expensive and not easily found in Italy).

Since you are seeing normal picture and color from the RF output, your video boards are probably still in good working condition. The lack of video from the SCART output (and B/W from the SVHS output) may be caused by a fairly simple "mechanical" problem (broken or failing cable connection between boards, or loose/cracked solder joints at the outputs or on a board). This is a typical issue handled by ordinary video, audio and computer repair shops: any shop that repairs stereo systems or TVs should be able to examine your FS200 and fix such problems at a normal cost. I would not discard this FS200 until you have had a technician examine it for these simple connection failures: it is very hard now to find a FS200 with nice clear color (many have serious, repair-resistant video issues).

This type of "professional" Panasonic is unusual compared to most other Panasonic VCRs: it has several circuit boards and several potential failure points between boards and outputs (other Panasonics have just one or two boards with more reliable parts). While annoying, these simple connection faults are simple to repair (tho if one of the actual cables is bad, or one of the internal multipin connectors is broken, you would need a donor FS200 to replace the parts). Have this VCR looked at by a TV or PC tech before you give up on it: perhaps provide them a copy of the service manual PDF file to show where the connection points are buried inside.
