Maxstar 200sd disassembly problem

[MinnesotaDave]

Well, this seems like a stupid question, but while trying to take a burned board (200841) out of my maxstar 200sd, I can't get it to release from those 12 pin black connectors.

Seems like this should just pull right out right?

Thanks for any advice guys

I just pry up with a flat blade screw driver on both edges

Thank you for the response cruizer

I take it you mean between the two black plugs?

I was concerned I was pulling too hard, just need some leverage - good to know.

Inverters are new for me, but I figured it was time I got comfortable with them

[cruizer]

did you do a pre inspection on this thing to determine that the inverter board shown in the Picts was the only thing that was pooched?

Seldom does a inverter board go by itself.

The left memory/control card will go and not take anything else out, but the right inverter board generally takes the mother board out. It's usually the mods under the mother board that takes it and the inverter board out.

I re-formed a screwdriver and got it apart, you are correct - the main board (200851) also has some damage.

Do you have any preferred shops that you can recommend that I send the boards to?

The small board (200841) only lost about three small components in the lower left corner.
The main board lost a few more.

Not repairable, have to replace the mods, mother and inverter

[MinnesotaDave]

The boards aren't repairable, or the welder isn't repairable?

"Mods, mother, and inverter."

Could you clarify please? I assume you mean the mother board 200851.

What does mods and inverter refer to?

[cruizer]

Mods are the preregulators under the mother board/interconnect board, that the inverter board attaches to. These are 3 layer boards, unlikely to be repaired by any firm

Are you talking about the part listed as "kit input/pre-regulator inverter"?

Is a failure of that component what burns the boards?

In general, is this machine repairable?

[cruizer]

Tough call, really up to you.,

Tough call, really up to you.,

What are your thoughts on the part listed as "kit input/pre-regulator inverter module"?

Is that what you refer to as a Mod?


Is a failure of that component what burns the boards - or is a burned board a stand-alone problem?

Just trying to wrap my mind around inverter machines - thanks for your time

[cruizer]

Yes Generally a loose mod causes the rest of the problems

The screws through the main panel and mod were tight in this case.
