PGM4 repair

Tue Nov 21, 2017 2:23 am » Post: #1 » Download Post

Hello all,

My MC-28's PGM4 works fine however the plastic slot that the card slides into has been damaged from an earlier crash. I have a used replacement plastic face-what is involved in swapping this plastic cover face? Is it a simple unscrew, or is there more involved and do I risk damaging the electronic internals of this item if I attempt to do so?

Thanks, Frank

The plastic face is wired to the main unit and has the card reader in it, you can unscrew it and remove it quite easily but you will have to cut and re-solder it to the main body. I am still unsure if the electronics that recognise the card are in the plastic face or the main body of the PGM. I presume the replacement you have is a complete unit that doesn't work or is it just the plastic part?

Once you have done it you may find that it no longer recognises the card. I have several PGM's in different states of damage so I am interested to hear the outcome. Smile

I only have the plastic face...I hope to work on this over the summer break (southern hemisphere). I'll keep you posted, cheers

OK, does it still have the ribbon cable that is attached to it?

I will try to get a picture of an opened up one at the weekend.
