These types of vid are most helpful. The items that are "not worth fixing". Appreciate your excellent videos and I am on your patreon monthly for as long as I can afford to do so. looking forward to something on LD Players
One of my LD players is acting up again so i will pull it from service and get it up on the bench again. it was one I bought cheap and service at a while back and it has been fine except for there's a few discs that it is kind of picky with so I might try to get into that and see if I can make it read those picky disks again
It ran when I parked it. What brought you to your channel originally was my high end Sony VHS. It has the dreaded broken blue gear problem. I haven't gotten around to fixing it yet.
What an odd scratch, the chances that a hard particle ended up under the motor rotor. I expected a failed hall effect pickup, nope i was wrong as normal :-D
For me, I think this one would've lead to much head-scratching! Well-spotted! Had the same no drum rotation fault with a similar-age JVC. Easy-peasy; turned out to be the ICP fuse for the permanent 'drum 12v' line from the chassis was o/c..
I wanted to ask if you knew how to do something cuz I saw your videos on your channel on UA-cam where your repairing VHS tapes. Cliche as this may sound, my dog got a hold of a VHS tape of mine and really did a number on it. She destroyed the case and cracked the spools and ate part of the spools, however, the tape is just fine. I know how to disassemble the case and I understand how to thread the tape through the rollers and I understand the entire way the tape operates. However, what I cannot figure out is how to transfer the role of tape from the spool it's on to an empty spool, short of manually unrolling all of the tape off of the damaged spool and then manually rolling it all back on to the new spool. There's got to be a way to disassemble the spool that the tape is on and just remove the tape roll from it. But I sure cannot figure it out. If you can help me with this I would appreciate it.
@@crashbandicoot4everr I believe he was talking about seperating the reels so that the pancake of tape can be lifted off and placed on another hub. This is what we used to do with film. I have a 16 mm film reel that you can spin open and then drop a pancake to film onto the Reel and spin the top on.
I like on this VCR that the P2 and P3 guides are metal. I had to replace my plastic ones when they snapped. For the same reason I use my Panasonic NV-HS950 more often than NV-HS1000. The mechanism is exactly the same (K mech) but 950 has metal guides. Shame that all the Z mechanism VCRs have plastic guides.
Don't tell me about that! I bought a Metz VF61 (Panasonic NV-HS860, Z mech), all was wrong with it was adjustment. Someone adjusted the heck out of the guides. That was when I realized, the super fine adjustment thread is in the plastic, too! I thought the plastic guide base has some threaded metal inserts, but they don't! And that is disgusting! What were they thinking?! Fortunately the Z mech is very common, I stole the two guide bases out of a 2-head Panasonic VCR, which I bought for peanuts with broken video heads, exclusively as a mech. part donor (I have at least 5 of them since then, and two Z-mech S-VHS Panasonic VCRs, the NV-HS860 with the Metz logo, and a Panasonic branded NV-HS850).
Thanks for the video;are you experts on old VCR?; i have an old VCR Sony SLV N60 and I'm trying to use the vcr as a RF converter to send video from a streaming box via HDMI to an HDMI to RCA converter to RF coaxial to the hole Apt ,i was able to make the set up and connection ,i connected RCA cables to VCR input line 1 but in order to see video from the streaming box i have to put a tape in the vcr and press play and i can stop play and video stays on. I have to do this process every time i turn on VCR .Any clues why? thanks
Now, I'm wondering why the drum was rubbing this board in the first place and will this problem happen again. Was the PCB too close to the drum? Was the drum too close to the PCB?
And why it isn't rubbing now? Maybe the board deforms with heat? In a hot summer day, after hours of use when the motor drive IC also heats up the board, it might happen again. I would probably put a few tenths of mm spacer below the board, it would not affect the operation of the motor, but give a bit more room for the rotor.
Maybe the VCR was operated with something heavy on top of it (or even someone/a child put a foot on it), forcing the top cover to slightly bend and touch that drum PCB.
I really wonder what caused the edge of the rotor rubbing against the PCB, any why it doesn't do it now? Maybe someone operated the VCR upside down, and the axial play of the bearing allowed the rotor to move a bit closer to the stator? Yeah, this is probably Sony's last VCR series, that was really made by them. Later ones were SonSungs (Samsung OEM). They haven't even bothered to replace the icons in the OSD...
Yes apparently so. Is that the only thing I did other than unplug the flex cable to remove the stator assembly and put it back on. As you saw I measured between both sides of the trace and it was open. Perhaps some debris or dirt got on the board in that area that was caught between the rotor and the stator and just over time it rubbed it enough that it severed the trace. The only thing I did was 10 over the trace where the rub Mark was and then continuity came back. Plugged it in and away it went.

I have another one with the broken blue gear I will be fixing so I can sell it.

Fixed my VCR thanks to this video! Thank you!
Do you have a Teardown/Dismantle of SLV-E730 Head (showing washers etc) ?

They don't come apart.
All VHS tapes have a tape retainer clip on each reel. Unclip it and the tape will become free from the reel.

Nice find on the rubbed trace. Yeah I fixed a Walkman for a friend this week and he bought me lunch too :)
Varta -- my sworn enemy. -8HP on many a motherboard...
Good Fix. I put in proper belts to my Sony CFS-E14 casette deck, well now it plays fine but no Rew/FF :D i guess i really only need the play function
Check the idler

You should scrap the damage trace, then apply flux, and then bridge it.
Not everybody needs flux, Dave has been in the business for a long long time..

Hi how are you doing today
I woke up this morning so it's a good day.
Hi! I don't understand! Is that a just broken trace problem?
Yes apparently so. Is that the only thing I did other than unplug the flex cable to remove the stator assembly and put it back on. As you saw I measured between both sides of the trace and it was open. Perhaps some debris or dirt got on the board in that area that was caught between the rotor and the stator and just over time it rubbed it enough that it severed the trace. The only thing I did was 10 over the trace where the rub Mark was and then continuity came back. Plugged it in and away it went.
Sir do you know 6552 ic equivalent
No
Will the trace you fixed get worn down again?
Who knows. Didn't hear anything rubbing.

Liar!
