Nanao MS8-29FN22 - IC 402 Daughter Card

[Plymelk]

I came into a Nanao MS8-29FN22 chassis recently that I intend to rebuild as a back-up chassis and perhaps use for a Frankenstein monitor in some other project. However, I noticed that the chassis's pincushion adjustment daughter card at IC402 has been desoldered and removed. The daughter card is the tall card to the left below with the variable resistor and 4 electrolytic caps. The MS8-29 manual just lists this component as an IC rather than describing the values. Pictures across the internet do not provide enough detail to make out all of these components. I believe the MS8-29FSG has this same daughter card.

If someone has a spare daughter card that they can snap pictures of, front and back, or can send any information available on this daughter card, that would be a start. Anything on this card would be a help to recreate this in someway

Many thanks, I now know that IC2 on the board is an OP amp by Mitsubishi. The tricky part is going to be determining the traces on the back of the board to clone it. Doesn't look like one can easily photograph the back of the daughterboard with that stand-off and heat sink in the way. Thank you imbord3rlin3!

hold on

Wow THANK YOU! Last request I promise, I need to know what IC 1 is on the board, it’s the array very close to the pin header. I owe you a beer sir.
