As I mentioned, the chip has been discontinued for some time. I've had to repair a good many --some are easier than the others depending on how the cap failed on the IC. While it's rather routine for an experienced tech, not sure if it's worthed to you? Personally I could care less for vcr/ video tape--still do repair them because it's part of the business i'm in. It's a dying technology & definitley on it's way out.
You could easily get a newer machine that will do the same job for much less but'll never see the quality built of yester year equipment. |

| The only reason I'm worrying about it is because I have a couple of SVHS tapes that I would like to transfer to DVD. |

Just an update for anyone searching the web and finding this post. I have a Mitsubishi HS-u70 (except, because it's from Canada, it's labeled and Electrohome AVR G95 ), that had a problem playing SVHS tapes.
The machine played VHS tapes just fine, but SVHS tapes would be very dark and have verical rolling issues, and the tracking couldn't lock on.
with vtech's help, I identified the IC board, and removed it. Sure enough, the cap had leaked.
I removed the cap and soaked the IC board in alcohol for an hour, then scrubbed it with a toothbrush.
The capacitor on the IC board is a surface mount 4.7uf, 35V type. I didn't have anything SMD, so I dug through my collection and found a bigger one with the same capacitance, but higher voltage of 250V. I soldered wires to the IC board and connected them to the capacitor leads, The capacitor can be tucked neatly into one of the holes in the frame.
And...IT WORKS! Not the prettiest solution, but who cares ? I can play my tapes!
If the pictures don't show up, they are all available here:

Again, a HUGE!!! thanks to vtech for his help on this. I would have had to search forever to find the problem, but instead, I was able to fix it in almost no time. THANK YOU!
Hope this helps someone else bring an old marvel of technology back to life! |

Another pic:
Shows the IC board in the main board, and the capacitor in it's hiding spot. |
