I readed about the secam system and use one line for R-Y and the following for B-Y, this has less interferences but less lines of colour, I readed in wikipedia

This remember to Betacam system that has R-Y and B-Y compresed in one field :)

But betacam has other head for luminance :)

I saw the COCORICOCOBOY program and has good colour

In youtube all is deinterlaced, do you send me a small fragment interlaced?

No, as I said in France analog TV (secam) broadcast ended in 2008 (in fact it completely ceased in 2011 but digital TV was available since 2005 in the big cities and in 2008 in the whole country) then SD 720x576 digital TV has been replaced by HD 1920x1080 for a few years now.

But all my Betamax tapes were recorded in SECAM, and a lot of my VHS and DVD's as well (DVD were transcoded in Pal during recording but not the tapes) until 2008.

All good Samsung and LG flat TVs sold in France are able to display a good playback of SECAM tapes without artefact. (And also Pal and NTSC).

One good thing from the SECAM was that it had (and still has on my tapes) brighter colors and an outstanding contrast compared to the dull Pal system. You can see it on the Beta videos I uploaded on my Youtube channel, those starting with the Beta logo.

I repaired my SL-C9 F thanks to Ebay because that was the only place to find SL-C9 parts and junk SL-C9 for a very reasonable price (I had to buy 2 junk units, 25€ and 150€ + some little parts) in order to repair my own unit.

I was lucky that the only "big" board that was not struck by lightning in my C9 was the RV8 (Y/C video board) because it is a SECAM video board and all the SL-C9 on Ebay are PAL units ! Never saw an SL-C9 F, only E, ES, UB, AS, etc. but never F !!

SL-HF100 F are common and easy to find in secam here, they sold a lot in France but not the C9, it is a very rare unit in SECAM.

No problem with interlaced videos and any kind of video sources on my plasma TV !

In Spain in 2006 begin the digital television and was removed the analog, also there are channels in HD

Why do you repaired your Sony SLC9 F thanks of ebay?

I go to see your youtube channel and I will tell you my opinion

Do you can see interlaced video in your plasma?

David,

I am a musician too, and I only listen to music on a "vintage style" high range (big) hifi ! I am not saying at all that compression is great ! I am not into Mp3 or DivX. I hate little screens, Iphones etc... Blu-ray is excellent, compressed full HD TV is correct most of the time but overcompressed picture is awful. In fact I hate to watch overcompressed pictures ! We don' have analog TV broadcasting no more since 2008 in France, do you still have it in Spain ? And all french TV channels are in digital full HD (1920x1080) for 4 years now. I only take what is good from the present, blu-ray, good large flat TVs etc. and preciously keep what was good in the past, my Pioneer Laserdisc CLD925, my VHS hifi VCRs and of course my 3 betamax ; Sony SLC9 F (purchased new in the 80's and kept new in a box for 35 years as it was struck by lightning and no repairer wanted to repair it at the time, but I did it myself successfully recently thanks to Ebay, so it is one of the very rare SL-C9 F working as new in France (as they didn't sell many "F" secam versions) and I also like very much my SL-T50ME and my SL-HF950 ES, all being able to play my old SECAM beta cassettes... ! I agree, youtube picture is not fantastic at all , but it is acceptable if you watch the higher def, 1080. If you don't have good quality internet you can use the software 4k Video Downloder to download 1080 versions on your PC, but the internet lowest quality in France -20 mb/s- is OK. (With a good I7 PC for instance). It all depends on the quality of the picures uploaded of course. I have a youtube channel on which you can watch things that I like from the past and the present. Also, good things from the present are HD digital camcorders (Sony's HD 1080 are very good, got several of them, but my first SD JVC was not very good) you can watch the videos I made shooting my favourite cover bands from the south of France (especially Cocktail De Nuit and Les Méditerranéens) this quality would have been totally impossible to achieve in the past (lightshows are the most difficult things to shoot) and I think Youtube picture even with its strong compression is still acceptable provided that you watch the 1080 version. (My YouTube channel is : https://www.youtube.com/user/KStarDid ). Concerning good compatibility between old VCRs and digital TVs you must make experiments, as I said sometimes it works (fine with my plasma) sometimes it doesn't (I have seen awful VHS pictures on some LCD TVs) your eyes must decide, it is easy to see if there are bad artefacts, lines etc. or if the picture looks natural pure and great...! But again you'll have more chances to find a good combination of analog VCRs and digital HD TV with models from LG and Samsung than from other makes, that's what I experienced.

Frandid, the plasma tv has very good resolution the problem is the compresed signals that caused distorsions in motion images and static zones with one colour as the cartoons

I live in Spain and here the dttv has much compressed for obtain more channels

I saw sometimes the tdt but I prefer the analog tv with a good antenna

From various years ago the business want sell more big tvs and is more important the quality that the size

The mayority of Spanish people don't want hifi teams as in the past, now with a mobile phone with mp3 and very compressed videos there are happy

If the gears not allows bad quality the people not use, as the lp in vhs and the mp3, mpg and divx codecs and prefer deinterlace all videos :(

Internet has the fault, but without internet I can't write this, has 2 sides

David, honestly Beta and even VHS tapes look very nice on my LG plasma TV yet of course the definition has nothing to do with blu-ray or digital TV brodcast. (240/260 lines vs 1920x1080). It looks much better than on my older Sony tube TVs. And taking in account the size of the screen which is much bigger I think it is very good indeed. I think the more important is the electronic treatment between analog and digital. There are huge differences from one make to another, and I noticed the LG and Samsung are far superior to other makes. (I was very disappointed by Sony and Panasonic TVs, and Chinese makes like TCL, Philips, Hisense etc. which are really bad. (Well Philips is not chinese, but their TV are made in China !). And I am quite a perfectionnist concerning audio and video ;-) I think I will replace my old LG Plasma by a Samsung UE75 3D series which really has an outstanding picture, almost as good as my plasma and is bigger.

Frandid, I think that is better use a tube tv because the plasma tv deinterlace and the pal system was created for interlace tv

The deinterlace videos of Pal cause 25 frames by second instead 50 pair + odd

In the pcs are the same, if don't apply a deinterlace filtre appear saw lines, and if apply lost the original format, I only see videos in my tube tv with analog videos

The youtube videos not has quality for me

Also appear fuzzy images because the plasma tv not has 576 horizontal lines or a multiple, in vertical lines are very good but the Betamax only has 260 lines

David, the drop out compensation of my SL-T50ME (same series as the T30 ) is not as efficient as those on my SL-C9 F and SL-HF950 ES (but more efficient than those on the SL-C6 F etc.) , so some horizontal little short white lines appear sometimes on worn or low quality tapes. But picture is more pure, colors (especially red) are more natural than on the C9 and 950. This is normal. My display is plasma full HD 130cm TV, but as it is getting old (9 years) I will probably soon buy a 190cm 3D, because they now (stupidly) cease making 3D TV sets...

Kevin the white flashes not happen in other videos that I played the tape, I will check the drop out compensator and the croma section because only play in b/w and in the pause has much snow

The horizontal dark lines through the picture in large areas of red is because these videos not has guard band as U-matic and Betacam?

I am very interested in why happen this

In the SL-F30 in the C comb part there is a potentiometer that when I moved the dark lines appear more or less dark

I can send you the service manual in pdf if you don't has and do you want see

David:

The shimmering or even in some cases horizontal dark lines through the picture in large areas of red is normal to many vcr's. Some are better than others.

As for these white flashes you mention. Those are drop out's and will be worse the more tape wear there is, or if the drop out compensator needs a tweak.

Sony beta's seem to deal with this slightly better than the Sanyo models.

But once again will depend on the parameters I've mentioned.

Kevin, I played a tape near the finish, where needs more force and now run good but appears in b/w with many white short lines but not jump the image, this was with I bought the SL-F90

In your videos with a tube tv and the control colour high do you see a horizontal lines tremble in the red colour or colours that contains the red?

This happen to anybody?

This happen to me with a SL-C30 and SL-F30 with original tapes and recorded from the tdt

Too with the vhs videos but not with the tdt and U-matic VO-2630 in the same tube tv

David:

If the reel brake solenoid is working then you can count that out.

Have you checked the motor magnetic flywheel. If the base bearing is worn then this magnet will rub the coils ,eventually causing a short if left long enough. This will also cause low torque in the play modes.

As for the readings I have no idea, i've never had to check those.

Also could not see those images, the link doesn't work for me.

The cables from sensors of rec and cassette in are good (very low resistance)

In the solenoid more near of tape, between common and a cable has 141 ohms and between the common and the other cable has 18 ohms

The voltaje in stop is 0 between common and each cable but in play between common and a cable has 11,22 volts and with the common and the other cable 1,38 volts

Are correct the measures?

Kevin, when I play works the two solenoids

https://titulos.000webhostapp.com/VIDEO.JPG

I play with tape and without tape as in this image, the reel of the right has low force in play, I stop with the hand easily

In fast ff and rew the 2 reels run with force

What function has the gear that I put a arrow?

I recently purchased a Philips V2840 and new to this format. Very foreign to me for I have always owned/serviced U-Matic/Beta/VHS decks in the past. It seems impressive for its era. Does anyone know where one can source some good blank tapes, new or used.

Thanks

What I will do is take a note of what is put on there and maybe we can come to some conclusion as to what they might be for.

Thanks again......................Kevin
