Older Mitsubishi PIP bypass

[Cutty Cunningham]

The video rolls on my Mitsubishi CS-35803, but audio and menus are
perfect. My pip board is a 930C812-012 with discrete electrolytic
capacitors. I have replaced most of the caps, but can't find the 47
mf non-polarized at my local store. Anyway, the problem is not fixed.
I will order the other caps via the net, but does anyone remember how
to bypass this PIP board? My two plugs are 9 pin and 11 pin. I
verified that with no PIP board, there is no video. I also tried to
bypass the PIP board with a substitute 9 pin with a 47 mf and a 0.01
mf cap in a couple of configurations (looking at the bypass for the
newer boards with the 11 pin plug), but this didn't solve the rolling
video. I think the PIP board is the problem, but a bypass would tell
for sure. Thanks.

Do a Google search for that problem and you should find your answer. Look for

I looked thru about 25 pages of postings, but all were directed at the
boards with the SMD caps and the 11 pin plug. My board has a 9 pin
plug and I didn't find any info about this type of PIP board.

Could be because nobody ever bypasses these modules. It is very unusual to
have a PIP problem with these. The problem is more likely in the switching
circuits or video signal path. The sets after the series with the SMD cap
problems have very few PIP problems at all.

I suggest you get a service manual and troubleshoot by tracing the signal.

True. I have had several of these over the years that had problems both on the
main board and the AV input board causing various sync issues. I can't recall
ever having a PIP module like this one fail.
