Default Sony MCZ3001

I have a D board out of a 36"sony that has defective chips. One of
these was evidently replaced by someone else at some point. There are
two chips on this board. One is a DB and the other is a D. Is there
any difference between the two? Also my distributor has original Sony
chips for 17.98 and Hitachi's for 7.95. If I use Hitachi parts will I
run into any problems? Thanks, Lenny

The DB is just the newest version.

Mark, are'nt these chips made by Shindungen?
Might be ok to use the cheaper one marketed by Hitachi.

However, I think i read somewhere that the newer one, "DB", was an
improved design to address flaws in its former "D" version.

We've been getting them from Sony and just recently from B & D Enterprises
in the States. B & D has them for about 8.99 if memory serves. Sony is 16.00
each for authorized servicers.

Yes, the DB version is improved - and the only one Sony ships anymore, and
that is what they use in their own factory service.

There are a few things we actually get much cheaper from Sony. The TDA6108
CRT drive IC is only 5.00 from Sony - more than 3 times that from B & D.
