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. |

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

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 |

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. .

If I was going to go to the trouble to re-cap a VCR I would probably do one or both of my HR-S5800-HR-S6700 pair from JVC. Only difference between them is cosmetic. Those are/were really nice machines in their day. But on some of those modules hifi audio in particular SMD caps fail leak and take out tiny circuit traces with them. |

Panasonic sure knows how to pack a deck with boards though (AG-1980 diagram below). They are nice enough to not even show the 3000 screws holding that mess together (not to mention the many capacitors that go bad). |

Many times, repair cost more than buying one on eBay.

Unfortunately ebay units are a crapshot at best. These VCRs are 10-15 years old now, and many of them beat up and never serviced. Chances are whatever you buy will have bad caps anyway.

May need more NIB vintage JVC...
I may be (but not sure) interested in purchasing a second new-in-box vintage JVC VCR. Except for the 1982 HR-7650U that I already purchased, which one is likely the next best:
http://www.ebay.com/sch/m.html?_nkw=...ahand0&afsrc=1 Seller has 10 different vintage JVC VCR models. The next, closest good one may be the 1983 HR-D225U. I believe in the concept that the older the manufacturing year, the more reliable it will be. Can anyone verify? There are three different mid-80s JVC chassis I can pick. Which one is the most reliable to you?

Personally I'd go for the HR-D830. Yes they can have their problems, but they are all fairly easy fixes.
