I found this in the Archives courtesy of Shoreline Electronics,
MITSUBISHI #PIP BYPASS 3
Solution to bypass the un-bypassable module 05 Version "930b552005"
Jeff Stielau : Shoreline Electronics Repair
Found this one the sci.electronics.repair forum....did not try it yet but
may be a good fix !
What we've done for this model is to put a 2.7k and 4.7k resistor in series
with the (-) leg of the 47uf cap to ground and tap the junction of the 2
resistors and run that to pin 11.
A simple voltage divider.
Did a lot of experimenting with potentiometers to determine the values
needed.
You could always use a 10k pot to do this and would have something that is
adjustable.
You will need about 1.7v p-p at pin 11 when done instead of around 2.7v p-p
that you get when simply bypassing with that 47uf cap.

Subject: [TechAssist] Need Mitsubishi pip bypass for one that can't be
bypassed
There was a discussion here a couple of weeks ago where someone had found a
way to bypass the pip on a set that it supposedly could not be bypassed. I
have a CK35702 that seems to fit that category but can't find it in the
archives. If possible please repost this information.
Thanks,
