Sony Replacement CRT Wanted
A friend of mine out in AZ called me tonight looking for a CRT to replace
the one in his Sony KV-32S25. He doesn't want to put a lot of $$ into this set as it will be used in his kids' room. So a liquidator or service shop that's got one that they're stuck with from a cancelled repair job would be an ideal find as he's looking to keep the cost under $400. The CRT part number is 8-733-743-05. If anyone knows of a very good deal on some leftover stock, I would appreciate hearing from you. I'll pass the info to my friend, or put you in touch if you have the item for sale. Thanks. -- Best Regards, Mark A. Weiss, P.E. www.mwcomms.com - |

Good luck. That particular tube is known for premature green cathode
short failure. Virtually every one of that tube of that vintage I have seen in the last 5 or so years has all been bad in the same way. Why is the tube bad in this one? If it is the common cathode to heater short, a manual method of removing the short may work. IMHO that particular tv model is not worth putting $400 into it. $400 would go a long way towards buying a like new but used Sony tv set in that size that does not need repair. |

This was my general feeling, but the guy has been known to keep his car for more than 30 years and keep rebuilding the engine. Go figure... I don't know what the particular failure mode is--he didn't go into details. It was a call asking for help in finding a replacement tube. He doesn't have USEnet access, so I figured I'd put the question out here and see if someone knew of one available CRT. Things like TV sets are not generally worth fixing, IMHO. Even a working set is worthless. I don't own one because there's nothing on worth watching. :-) -- Best Regards, Mark A. Weiss, P.E. www.mwcomms.com - |

In any case, the tube is no longer available as a new part from Sony.
If he really wants to have the tube replaced, try Video Display Corp. out of Atlanta, GA if they are still around. They use to sell rebuilt tubes. |
