I'm trying to remove the broken LCD screen from an Acer all-in-one z1620. Other than the screws that hold the motherboard to the frame - what else is holding the motherboard in place? Am I trying to remove too many components or too few?

 

Found a helpful manual at http://www.manualslib.com/manual/232908/Acer-Aspire-Z1620.html?page=108#manual but it looks like I need to disassemble everything to get the motherboard out. There are 2 screws under the motherboard that I have to remove to get to the LCD. 

 

The manual indicates that I must remove: Vesa mount, EMI top bracket, Thermal Module, CPU, WLAN, DIMM's, KTS Battery, Mainboard, a multitude of cables, speaker wires, and finally the Mainframe to get to the LCD. Is it necessary to remove DIMM's - I don't understand how they would prevent the motherboard from sliding out? Pulled them, but I don't know why. I've removed many of the listed components -  but so far the motherboard is not budging. It is supposed to SLIDE towards the top of the pc and pull out.

 

Is there a trick to this? I'm getting nervous and do not want to crack anything in the case. Cannot find any video dealing with Acer all-in-ones. Would also appreciate guidance in trying to locate a new LCD screen - if I ever get this broken one removed.

 

Thanks for your help,

K

On page 109 it shows a yellow arrow to indicate direction try moving it that way.

Cryptodan,
Tried to move it gently in that direction - not sure where I can safely hold onto the board - unsure if I have removed everthing that I must to free the board...

Took off the EMI top bracket - but the side of the bracket is still wedged snug to the motherboard ports. Think I still have something that needs to be disconnected.

Really did not need to remove DIMM's, did I?

Thanks for looking.
K

If you haven't removed the dimms, then do so and see if you get better results.

Have You removed the CPU. I suspect that the 4 screws that hold the heatsink have a secondary purpose of also holding the Motherboard. That is quite common.

 

You do need to remove everything the manual tells You to remove. Having worked on Laptops and All-In-Ones (AIO) You need to follow the instructions completely.

 

I remember a Toshiba AIO where the USB receiver for the Wireless Keyboard and Mouse was holding the Motherboard in place when All else was done. Fortunately I was replacing the Motherboard under warranty anyway. That was a step that did not show in the manual. I warned our other location about that just in time as it turned out. It was pretty well hidden.

 

Good Luck

Roger
