Default Loewe Aconda ACO9303LS signal board IC531

This is a long shot, but we have this unit with an IC 531 on the signal
board gone thermal, losing sync. The IC part number is 350-28912 and is a
Philips SAA4977H/107. The signal board is available from Panurgy, the Loewe
support in the US for an absurd cost. The signal board part number is
396-87934.050. I cannot find a source for the chip. If anyone has any
contacts in Europe that might have access to the part, or has a scrapper, I
would appreciate a look.

Thanks,

Leonard Caillouet

Leonard, I'm not sure what that unit is but I used to work on Immix or
Scitex NLEs (which also had absurd service contracts) about 10 years
ago that had Phillips ICs with that same SAA prefix. Here's a link to
the datasheet for that http://www.nxp.com/all_datasheets/index.html
One thing I have done in the past is to call up Avnet http://www.em.avnet.com/home/
or Impact http://www.impactcomponents.com/inqu...talog0882.html
or some other big wig distributer that only deals with manufacturers
and tell them that I'm working on a design project with that
particular IC and may have a need for 10,000 or more but you need to
do some testing. I've actually gotten free samples of a number of ICs
that only the big wigs have. Not quite ethical but it does work. Do a
little sweet talkin'. On another note I have read your name on a bunch
of old Mitsubishi issues. I have an old CS3506 with color issues. Is
it possible to have a picture tube be so weak on green that a footbal
field or golf course looks red/purple yet the on screen display is a
beautiful green? I'm going nuts because I feel the tube is OK but I
can't find a problem in the chroma. Karl

Here is a link to the datasheet:
http://www.nxp.com/pip/SAA4977H_2.html

The chip contains a 16 kbyte ROM. It looks like the OP will need to go
to Loewe or Philips for the part.

That looks like one of those worthless chip brokers that hook your search.
Fine if you want 5,000 of something I guess.
