Another common failure on those decks is the plastic take-up arm gear on the bottom of the deck will crack, split in two, and then the tape won't load around the drum. I think the last one of those I did was on a SLV-R1000. Definitely a worthwhile investment for that customer.

Right. I should have mentioned the re-adjustment.
Thanks for the heads-up on the cracked gear. I never noticed that. I just aquired yet another machine like the ones I mentioned earlier. This one looks brand new, and has the remote. What cha want to bet that the pivot arm is stuck? Have a good day. I'm off to work, now!

Studio Sound Electronics preferred rankings...
I e-mailed Studio Sound Electronics, the largest online VCR part-store, on his opinion on 1980s to 1993 VHS VCR reliability, and he sent me this:
FEWER REPAIRS <<<<<
MORE REPAIRS Toshiba/RCA/GE/ProScan were the most-reliable, while Fisher was the least-reliable. Would all of you (as techs) find this (his rankings) more preferable and accurate? . Last edited by waltchan; 05-18-2012 at 08:10 PM.

1994-2005 VHS VCR reliability rankings:

MORE REPAIRS Sanyo was the most-reliable, while Daewoo/Audiovox/Emerson/Fisher/GE/RCA/Sanyo were the least-reliable. Would all of you (as techs) find this (his rankings) more preferable and accurate? . Last edited by waltchan; 05-23-2012 at 05:45 PM.

1988 Panasonic PV-S4880 S-VHS 4-Head Hi-Fi VHS VCR...
I'm servicing a 1988 Panasonic PV-S4880 right now. It needs a power supply caps rebuild, capstan-motor circuit caps rebuild, and video board surface-mount caps rebuild (photo #1).
Surprisingly, the Hi-Fi audio board use no surface-mount caps. Ed in TX, this is what the video board looks like in the PV-S4880 with the surface-mount caps (photo #2). Your AG-1830 looks pretty much similar.

After that, (you're not finished yet, despite the tired work), you also will need to check all the caps in the switching power supply, just in case, before you put the top cover back on. Panasonic S-VHS units often can get really, really severe electronic issues, with repair costs easily exceeding up to 500% of the product replacement cost.  .

Sony would be above Funai on my list. Hmm. Sanyo at both ends of the list. Interesting...

Is there any way for you to share this data? The issue I am looking into is how repair rates improve over time as products become mature and manufacturing improves. So I would love historical time series data for repair rates for VCRs.

Walt, I did a bunch of VCR repairs in the 1990s, for friends, but I never kept track of brands enough to remember now which ones I repaired the most. Two big exceptions to that, though: I never repaired any Panasonics or their clones despite seeing plenty of them, and I repaired every Fisher I ever saw, sometimes more than once.

I had to repair a Panasonic of mine, but it was mainly rubber parts that failed. This was a couple of years ago and it was an early 80's model.
I use a JVC digital VHS deck now, but I don't trust it lasting forever. It's loading mech kinda sucks.

That later list from 94 to 05 should have a few caveats. It is easy to see that many brands appear more than once, often at different ends of the spectrum. Mostly this will be due to a brand swapping suppliers of mechanism in this time, eg Sony did make their own but by 05 sourced their mechanism from Samsung, don't know which mechanism they rate as the better or worse (sometimes I have trouble working this out myself). And in the time before the Samsung mechanism Sony had a couple of different mechanisms of their own of varying complexity.
Philips went from Sharp to JVC to Funai in this time. Keen eyes will spot that Funai drops significantly down this list, reading the wikipedia article says that about 1993 they dropped Shintom as their mechanism supplier and starter making their own (which is my opinion were diabolical, much worse than their pretty poor most recent mechanism) As you can see, Shintom stays high on the list. Sanyo is a bit interesting here, did not like their own mechanisms much of this period, then they swapped to Daewoo and things got a little better I thought. The early Daewoo decks of this period are hard to keep going nw though. JVC were a really mixed bag in this period too, with some good mechs and some not so good

I don't have much experience like most of the people here, but my Uncle had an Akai TV that broke, since I have only seen 2 CRT's actually bite the dust in my lifetime (the other was our old 80's unit) that is pretty significant. I don't have any experience with Akai VCR's but that is my experience with their TV's. Of course this is just one story from a consumer....
As far as VCR's I had a RCA that bit the dust last year, it started eating tapes, and I was mad because it ate something that I had recorded that I like. It was actually a good unit with a nice picture. I recycled the unit. VCR's are a dime a dozen, they are as low as 50 cents here at yard sales. Its easy to find one for a dollar if you are patient. I never pay more than $3 for VHS. Our family blew through probably 3-4 VHS from the late 80's until 2004 or so when we stopped using them extensively. Of course they are still in use though, I have plenty for spares!

Added pictures of my mitsubishi HS-430U to post #31 since there can be some confusion with the newer "HS-U430".
