Sir Sooper Dooper HandySuperman . . . . . . ( but possibly ? . . . .not being quite so adequately illuminated in its electronics aspects)
Need that photo re hosted offsite for presenting a LARGER display, from what I CAN now make out, is a common OCCURING AND OCCURING AND OCCURING mistake, being the misinterpretation of some yellow "pookie"/ wall board adhesive being used for a physically large components hold down.
Thinking it as being the oozed out guts of an E-cap. ( Your LARGER RED arrow is pointing to that defined area. )
The circuit boards top left corner shows their cheapening / gutting out of some components normally being used in the AC power input circuitry.
I don't see your "stock photo ? " . . . . ( with its full long leads) "X" safety cap, being anywhere on the board, and it would typically be the omitted cap that mounted just down in its square box marking, just below the RTC.
Your visible reddish brown cap, could possibly also be an " X" safety rated cap.
The bottom left corner contains the initial 4 diodes used to feed rectified raw DC into your probably good E-cap, . . .( missing) . . .to the right of them.
What seemed to be THE power transformers corner in your 1st photo, is now relegated to a standby power supply duty with the MAIN unit being located down below it.
( Any chance that this unit has a remote control hand unit ? )
Need full info on the two power units marked on ID's . . . mounted on the dual heat sinks.
The main Matsushita 16 pin IC .......w.....a......y....... over on the other half of the board, is too far remoted to feed / relate to those 2 power devices, so one should expect their driver and I.C. controller brains to be contained within a flatpack SMD IC, that is being mounted very near to them, on the other side of the board.
The MAJOR power supply output will be going into the boards bottom centrals . . . dual Schottky rectifier, screw mounted to its quite ADEQUATE roaming L form heat sink.
It outputs into the round toroidal filter and then into its adjunct mounted TALL boy E-cap.
Some additional windings for other minor power supplies should also come from that transformer . . . used for . . . ..
The rest of that board half, and its two IC's, that seem to be related to your cooler control and temp aspects.
You do seem to have two B.uilt I.n T.est E.quipment notifiers , in the form of those RED and GREEN rectangular LED's . . . any illumination coming from them ? . . . . . . . . . . .but then, they may be related to the cooler indications aspect or for fans being powered / operational .
Do I just count 3 connectors on the right board half ?
Do you read a DC output on any of them ?
