Do you have a service manual, or a schematic for these units?

@@zulumax1 I thought I replied to this earlier. I do have the service manual. It comes up once in a while on the bay. You can find the E version service manual as a PDF. It's not much good for the electronics though because it is way different. The mechanism should be the same though with the exception of the heads.I would scan it in but the pages are very large and I don't have a good way to scan them. The page with the power supply isn't too bad though.

I have just repaired 4 of these JVC HR-D470U VCRs with a failed capacitor in the power supply. It's C17 - 3300UF @ 16V. The symptoms were SP tape not being played at correct speed. It was trying to play at EP speed. Basically no picture. The capacitor is right next to a heatsink and gets cooked over the years. 3 had one leg rotted off! If you are having any problems with one of these decks, I would check it out. I used 105° C caps instead of the 85° C the factory installed. It probably wouldn't hurt to check the other caps too. I think there are a total of 12 electrolytic caps on the power supply board. If you have a dim display, you may have some of the other caps in the power supply bad too.

Did you find the cap with an ESR meter? Bulging? Pissing juice down one leg and eating the board, I know the drill. I repaired my sisters ECU computer in her 1993 Toyota Camery. Had to repair some foil runs that were eaten away. One of the VCR plays at the wrong speed, so will have to check it ASAP!

Yes, one of these decks has that exact problem, but I think it is a parts donor and not in good cosmetic condition, so I didn't care to fix it.

@@zulumax1 It looks like it leaked very slowly because it wasn't on the PCB but the leg was rotted away. The top was actually bulging. I did test with the Blue ESR meter. It tested completely open. Several others were bad in the original one I bought new too.

hi a side loader hi-fi usa only the best format for sound is the betacam decks i have tryed vhs betamax hi-fi and i still think the betacam is the better because there 4 audio channels and there's alot of parts still around in the uk and they don't sell well in the uk yes i have been buying them up and fixing them love the front buttons and all the toys on the decks

The HR-D470 had a UK / European version too. It's not really fair to compare this with a Betacam deck. Betacam is a professional format, not a consumer format like HiFi VHS.

@@TheVCRKing There are actually 2 belts. One mode belt and one for the loading mechanism. The mode belt is very difficult to change because you have to take part of the mechanism apart. Things must be kept in the proper timing or it will no longer function. The loading belt is easily replaced. Luckily JVC used very high quality belts and you might get by just cleaning them with acetone or alcohol.

My guess would be the "U" would be for USA, and "EK" would be Europe and/or United Kingdom. Voltage and plug receptacles.
