Okay then, done. Just copy and paste, no translation. Här kommer en redovisning om reparationen av min CLD-R7G. Först och främst behöver man ta av locket på den vilket är en baggis. Två skruvar på höger och vänster sida samt tre skruvar på baksidan. På baksidan sitter även ett fastskruvat lock som skyddar lasern vid sidbyte och denna kan man ta bort redan nu. Jag slog på spelaren och sköt ut släden. Efter det drog jag ur kontakten och lyckades ta ut släden ur spelaren genom att hålla in de två spärrarna som sitter på den. Se hänvisning på bild, det sitter en spärr på vardera sida av släden. Efter det tog jag av den övre skivhållaren som sitter fast med fyra skruvar. Nu kommer den lite kniviga biten och det är att få bort den övre rälsen. Först och främst går det en röd kabel till en enhet man använder för att ställa in linsens fokus, bry dig inte om att justera denna men se till att kabeln inte sitter fast i någon av de två plastspärrarna som jag noterat med nummer ett på bilden. Kabeln sitter också fast med skruv tre. Längst skruv sex går även en jordkabel och denna kan du placera i hål sju så att den inte kommer bort. När alla skruvar har tagits bort, var försiktig med rälsen som skruv fyra håller fast! Se till att du skjuter upp den lite försiktigt underifrån (tillsammans med den övre delen) och att du sedan tar ut allt genom spelarens baksida. Är du inte tillräckligt försiktig kan rälsen mellan de två sidorna gå av och även om det inte brukar vara särskilt svårt att ordna så är det bättre att ta det lite försiktigt. Nu när den övre delen är borta så är det dags att få ut lasern. Börja med att lossa kabeln (nummer två) och skruva loss laserns spärr (nummer tre och fyra, skruvarna syns inte på bild). När detta är gjort är det bara stångens spärr som är kvar och det är nummer ett på bilden. Ett tips är att man sakta lossar lite på den med en tång och försöker skjuta upp stången med en liten spårmejsel, här kan det underlätta om man är två. När stången är av så är det bara att ta av lasern från den och byta hållaren. Jag tog inga bilder på när jag bytte hållaren, men det svarta som sitter framför motorn är hållaren som skall bytas. Den sitter fast med fyra skruvar varav två är i lasern och två är i motorn. De två kortare går in i motorn. När man byter motorhållare så ska man se till att man sätter i den större kuggen först, den sitter i den nedre hållaren och ska ha huvudet utåt. Den mindre kuggen sätter man sedan in i den övre hållaren och med huvudet utåt likaså där. När man har fått på den nya hållaren bör man testa så att den fungerar genom att dra lite på motorns axel och se till att kuggarna rör på sig. Notera att varvtalet är lågt och därför syns kuggarnas rörelse inte särskilt väl men tittar man noga så syns det till sist. Se gärna till att spåret på undersidan av lasern är ren, på den här fanns det några kletiga hårstrån som jag tog bort och såg sedan till att det fanns gott om fett i spåret samt att det inte fanns någon smuts på stångarna (jag har hört om folk som hittat sandkorn där, hemska tanke...). Efter det var det bara att skruva ihop spelaren och nu är den som ny igen.

Great! I will look more into it as soon as i can! I am also considering now to get some of that grease, sense i started to think that my previous solution might only work as a temporary fix. But isn't there somewhere closer where you can get it? I mean, there must be some European or perhaps Scandinavian/Swedish retailers of such a basic thing. Although i have searched quite a bit now, but with no results... Is there perhaps anything here that could be useful? https://www.elfa.se/elfa3~se_en/elfa/init.do?toc=19046&pageSize=10&filterClause=COL_2%253DLubricant

Today i finally got that grease in the mail! And i have now used nissling's guide to further disassemble the player. And guess what, both the pins on the M-holder was broken. So i replaced it with a new one. But now i unfortunately have run into yet another problem The flat cable that goes into the pickup seems impossible to put back. The plastic casing that surrounds the end of it goes all the way down. But the cable tends to squeeze itself upwards through that tiny little gap (see picture) Any ideas on how to fix this?

Let's take this in Swedish. Dra i det långa bandet (som jag kallar kabeln ) så att kontaktytan åker nedåt. Se till att hålla nere bandet med tummen när du trycker ner kontaktytan med pekfingret och tummen (på andra handen). Sedan ska det gå.

nissling wrote: Yeah this is complex science that needs to be told in native language and since we both speak Swedish I may as well do so. xD Even I understood it! From what I remember, I had the same issues connecting the cable. What I found out is this: I would unclip the plastic bracket (let it be loose but not remove it entirely from the cable) and move it backwards a little so you can firmly push the cable alone into the slot. Don't be afraid about pushing it back, but do it equally on both sides of the cable. Then you can move the plastic bracket back and make it fit. Make sure the cable goes straight back against the turn mechanism with as low heights on it as possible or else you will ruin it if the cable hits the disc during playback. My cable hitted the disc and made some nice irrepairable grooves on it.

But now for some more sad news, when the player was finally put back together again i noticed that you still need to help lifting the assembly into place. However this time you would need much less force then before the new belt was installed. Could it perhaps be of the wrong size? It seems that i will never get this thing working again!

krbahr wrote: Out of curiosity I ordered a couple belts from Pioneer and they are slightly smaller than the SCQ4.0 belts I've ordered. SCQ4.0 is supposed to be what Pioneer used originally. That will make the difference as I also had a few failures recently myself. I have ordered some SCQ3.6 belts and they are slightly smaller than the Pioneer belt. So the aftermarket belts are not always what they say they are supposed to be. I'm going to start ordering the Pioneer belts now or the 3.6. Interesting, didn't know about that. And yes, that might very well explain why this belt seems to be slightly on the large side. So, does that mean it would work if i should order the "Square belt 36 mm diameter, 1,1 x 1,1" from the link below? Or do i still have to order a couple of them to try out? (Will be quite expensive as they each cost's around $6.40) https://svalander.se/shoppen/reservdelar/remmar/fyrkantsremmar

This belt mysterium is also new to me. I was thinking of ordering some belts myself for the cld-d925 for the future. Did you, findlarn, buy the belt from this seller?

Yes laserpaal, that is the seller that i got it from. Also, i have now ordered a new belt directly from Pioneer's official Swedish service department. Wasn't cheap! Around $18.50 in total! So i really hope now that this one does the trick!

Quote: wasn't cheap, maybe you should have bought an LD player new back in the day, that wasn't cheap Well... Compared to belts i have ordered in the past, i would definitely say that this one was rather expensive. As an example, i did not to long ago get four belts to two of my Commodore 64 tape drives for about the same price as this one, and that even includes shipping from Germany... laserpaal wrote: You should now have some compatibility guarantee from Pioneer, if not, you should return it for a full refund. But I hope this fixes the matter you are dealing with and you can fully enjoy laserdiscs! You have taken great steps in fixing this player, so all respect to you. The positive feeling of enjoyment after fixing something of complexity is good! Yes, i think you're right about that. The mail that i got from them did actually say something about the right to return it if it proves to be faulty. But seriously, i think the risk of that happening is quite small. And yes, it feels really good to finally get this player working again. Especially when you know that these players aren't that common over here, and replacing one isn't really the easiest thing to do. And i bet the situation in Norway is quite similar. By the way, was LD ever officially released there? Or in any of the other Scandinavian countries? Here it was not, and the only discs that i can remember seeing in a store over here was always imported from the US. (As far as my memory goes)
