iMac G4 - removing the TMDS connector

Recommended Posts

Refurbishing a few iMac G4s and finding the TMDS connector attached to the motherboards are hard to disconnect. What's the trick? Should it just lift up or is there a catch / pinch needed?

I think they pull out sideways, I got a proto imac g4 logicboard here someone tried to pull up and ripped the whole connector from the board. I still dont know how to fix that yet.

Can you provide a photo of the connector you're referring to? I've disassembled a couple of iMac G4s to make lamps, and I want to say that each connector on the logic board simply pulled straight up. I really don't want to give you bad information, though.

I had this problem a couple of years ago. I can't remember the exact of it but I was almost ready to dig out a hammer it was so bad for one of my 2 iMac G4s. I remember pushing and maybe wedging hard to the point that I thought for sure I would break it when it finally let go. I can't remember how I did it though so please be careful. I love my iMac G4s and consider them to be among the best Macs ever despite them also being one of the worst dust inhalers ever. When you finally get your machines apart, they will be incredibly filthy with dust. I am really interested in your restorations. Both of my iMac G4s still work but have startup problems when cold due to what I am pretty sure are bad caps in the power supply. I would like to reopen up both of mine and fix this problem for good with better caps. There are one or 2 small electrolytic type silver can caps on the motherboard as well that I would like to replace with tantalums if I am going to go to the trouble.

 

There may be a good movie or two of iMac G4 breakdowns on YouTube did you check there?

Yes, although on the ifixit and the YouTube videos they flash past this step (or not cover it). Looking at one video the guy seems to be pulling it up (or across, as someone has suggested) but it seems to give easily. Against that, have read about the base falling off tables and ripping the connector out of the motherboard - so these are not MagSafe attachments!!

The connector is protected by a U-shaped piece of black plastic that is attached to the motherboard with some adhesive strips.

 

It feels very uncomfortable to pry it up, but I don't see how you could damage the connector itself. Just firm pressure (but quite a bit) is needed to detach the adhesive strips.
