Met some problems with my Jandy automation.

I have Pool and SPA.

ISSUES:
No lights at indoor panel. No any response when I switched to auto side on outdoor panel. (Pumps can work when I switch to manual)

STEP 1: I checked and found fuse burst. Changed new fuse and burst again.

STEP 2: I unplug everything except power cord from transformer, The fuse is OK.

STEP 3: The first thing I tried after STEP2 is to connect harness wiring cable to indoor panel, expected that indoor panel got power supply. But fuse burst again. At that time, I have nothing connect to outdoor PCB except power cord and wiring cable to indoor panel.
Test harness wiring cable: I unplugged wiring cable from indoor panel side, changed a new fuse, NO fuse burst. I think cable is ok. Multimeter told me the power from wiring cable voltage was 34v.
I concluded that issues are from two PCBs (outdoor and indoor).

Step 4: I unassembled outdoor PCB from cover and check it again, and found some black spot, not sure whether they were marks from burst, but looks unnormal. These are images from two sides of black spots.

Step5: Tried to find same PCB from Ebay or somewhere else online, but nothing.

I AM STUCK HERE!

Need some advice:
1. I can't find manual for this Jandy model. What kind of model is it from Jandy? Is 34v voltage on wiring cable(to indoor panel) correct?
2. Are these evidences enough to say PCB issue in my case? If so, is it repairable?
3. Where can I buy a new same PCB? Can't find same PCB via EBAY or google.
4. What's my best option for next steps? Is it feasible to repair? or dump this model and change to a total new system with some modern features?

Any advices are welcome. Thanks.

This is a very, very ancient Aqualink system, and it's really it's just a warmed over Jandy JI-x000 series that came out before the "RS" style Aqualink that we've had since the late 90s. You're likely going to have a lot of trouble finding any repair parts for this system - it has to be nearly 30 years old at this point.

To clarify - the fuse does NOT pop when the inside panel wiring is disconnected?

Does your inside panel look like this?

Jandy did/does sell a conversion kit for the JI and first-generation AquaLink to make them a modern RS system if you wanted to go that route.
 
After reviewing this upgrade manual I would not want the upgrade and I would not want the PDA RS version. It is not clear if they have an upgrade to the iAqualink RS version.


I suggest you consider starting fresh with either a new iAqualink panel or get out from Jandy and change to the Pentair IntelliCenter depending on what other equipment you have.

Yes, this is the inside panel.
Conversion kit, thanks for your information.

According to manual, the only problem is "Early versions of the Ji2000 Power Center with a single face plate cannot be converted. These units require replacement of the Power Center. See Figure 3."
Mine is not single face plate. I suppose it's convertible.
Am I understand correct?

Your panel looks convertible from the pics.
