VCR with TBC cannot play LP mode recordings? - Page 2

hodgey · #21 08-29-2023, 09:17 AM

If you mean NV-SD40 it would be similar to the earlier mentioned models as it has the same mechanism. It's a similar model just a year or two older, also no hi-fi if that is relevant.
If you mean NV-G40 that one does not support LP as far as I know so won't work.
Not aware of any NV-GD40.

If you want one that's easy to adjust, the newer (late 90s/early 2000s) models with the later mechanisms might be easier as they don't have the extra locking screw so you can just do as described in the link with the JVC and not have to worry about that.

Sorry to ask so much questions but Panasonic nv-j35hq will be good option if it's cheap? I think it has lp mode?

One issue with SP/LP/EP recordings is the video head configuration of the VCR. FWIW the AG-1980 has three sets of video heads; 49, 26, and 19 micrometer. (plus the HiFi audio and flying erase heads). The narrower video heads are used for EP record and playback to accommodate the closer track spacing. This reduces cross talk with the adjacent scan and may account for the Pana's better performance on EP tapes.

The JVCs S-VHS decks I've used have 2 sets of video heads.

Bargain basement VCR may have only one set of video heads; VCR's without the separate EP heads can not be expected to do as well.

J35HQ has LP yeah, though you want to make sure it's in decent condition as it's from the age that can have capacitor issues.

Not aware of any PAL VCRs that had more than 2 sets of video heads (Camcorders did but that's due to how they managed to use a smaller drum by I think by alternating 2 and 2 heads so that's different.). 2-head VCRs with LP playback were much much less common in Europe and came a fair bit later than 2 head vcrs with LP/EP in North America (though they did exist to a small extent, Panasonic even made a 2-3 2 head models in the 2000s with PAL EP/SLP somehow.) so that's much less of a worry here, the vast majority of VCRs that can play PAL LP will also have 4 video heads.

Finally I have bought Panasonic nv- sd25. Unfortunately it is ejecting tape. The film below is presenting this:

It can be repaired in simple way or not? Thanks for every help!

Something preventing it from going to the next mode, It could be a mechanical problem or a dirty mode switch, the first thing to check obviously is the mode switch, get a service manual for your model.

Can I clean it with IPA?

hodgey · #28 09-04-2023, 06:34 PM

If you are lucky it might work if you just go through the loading operation a few times, that has happened to me with vcrs with this mechanism. If not it's very possible it's the loading motor coupling that is split. This thread has a video link and some info about it. I have managed to repair it on a deck by epoxying it to the metal shaft rather than replacing it but whether that will hold up long term I don't know.

I don't think the NV-SD25 you got plays LP tapes though. There is a multi-system NV-SD25 that is 4 head and says so on the front, that one has a jog/shuttle wheel on the front so I don't think it's the one you got. The normal European variant is 2 head SP only as far as I can tell so it won't work for your LP tapes.

I am thinking about Panasonic nv sd435. I have checked it has z mechanizm, it's from 1998 and has LP. Will it be good option? It Has additional screws to misalign tape?

hodgey · #30 09-06-2023, 02:56 PM

That one should work fine provided you don't need hi-fi support. Z mech doesn't have the extra locking screws from what I know no.

araset · #31 09-20-2023, 10:25 AM

I have found Panasonic nv fj 612. I have checked it's from 2000, it has 6 heads, HiFi and z mechanism. Will it be good choice? Thanks.

hodgey · #32 09-20-2023, 11:44 AM

Yeah should work well

araset · #33 09-26-2023, 02:18 PM

It worked. I managed to align vcr to tapes. Thank You for Your help! I have a question about digitalising my tapes. I have read the post about recommended dvd recorders. Jvc seems to be the best but it's hard to find and is expensive. Is Panasonic es 20 also a good option? If I don't need professional results can I use SP mode and use only dvd recorder without tv card and results will also be good?

lordsmurf · #34 09-26-2023, 04:38 PM

The ES20 has LSI correct? It should remove chroma noise. But SP is still very noisy, use the 1-hour XP only.

Edit: Yep, LSI.
gshelley and myself covered it almost 20 years ago:

I was aligning my vcr to certain tapes and have no experience and have it misaligned totally. I can't find any image on my tapes or it's very shaky when I am finding it. Also has wear out a little screws. It's any way to reset these screws? If not how to set it properly? Are any keys/tools which will suit for such screws?

latreche34 · #36 09-27-2023, 10:03 AM

You need a service manual and an alignment tape with an oscilloscope, this how it's properly done, otherwise just keep aligning for tapes but you will never get it to factory condition without the right tools.

This tool is for aligning tapes?

themaster1 · #38 09-27-2023, 02:14 PM

The proper way to do it without a scope and get ok results (will never be like factory unless you have alignment tape + scope) is to first work with EP/LP tapes, then SP and finally SP Hi-Fi (retail tape preferably) . That's how i do it and got good results

Why is simple, EP (or LP) (slow speed)tapes are not as forgiving as SP, any misalignment (or realignment in your case) can be quickly seen on screen. So play with the 2 guides (P2/P3) Focus on pictures first the sound may be harder (Ac head adjustment is possible).
You should disable auto tracking in the menu if you can (manual mode will set the tracking to the center)

Some literature:

araset · #39 09-28-2023, 11:02 AM

Like I wrote previously I have misaligned my vcr totally and can't play any tape. I don't know if I haven't damaged it. Firstly it was so bad that my tapes was playing faster. But I managed to set it to play at normal speed and not play on it's own. Now I don't have picture but grey background and have sound. When rewinding i can see the picture.

themaster1 · #40 09-28-2023, 11:47 AM

What have you touched exactly? Only the P-Guides or the AC head aswell ? I bet is reel is too high on the P3 guide (exit) thus too high aswell on the AC head (= losing sync), remember the Speed infos (Sp/LP) is at the botom of the reel and Ac head aswell. Just make sure the reel is somewhere in the middle on each guide, pretty sure you'll get a picture

Happenned to me at first aswell, just persevere imo
