On this past New Years Eve, someone decided to do a NASCAR themed celebration with a champagne bottle, and unfortunately my "weather sealed" Sony A77 was present. The sticky residue jammed the main menu navigation button and I decided to replace it.

Below is a step-by-step guide on how to replace the rear panel.

To get the part number, try to make the Sony operator sympathize with you and give you a technical manual. I wasn't able too, but luckily, I was able to describe the part which needed replacing and the operator gave me the correct part number.

This goes without saying, but doing this will most likely void your warranty, but you know what? It is a hell of a lot cheaper than paying shipping and the $120-ish assessment fee Sony charges to trouble shoot your camera.

You will need a very small phillips head screwdriver. Something small enough to take apart a cellphone and a thin plastic business card or a mini pry bar.

Here we go:

I used just the small green phillips head screwdriver and the green-plastic-bar; but any thin piece of material will do.

This is the new, rear-button panel replacement part. The part number is 1-884-620-11. I purchased this from Andrew's Electronic. Look them up online. It was about $65.

Time to open up the Sony A77

I recommend doing this over paper that's taped down. This way you can tape down the loose screws and write notes as to where they go. This helps when you are trying to remember where everything goes.

First, remove the eye-cushion piece.

Feel free to use double sided sticky tape. If you place the screws on the tape, they don't roll around. Go ahead and draw a diagram if that helps.

This is the last screw to be removed before carefully removing the back piece from the camera's main body.

Carefully use a small pick to work open the seam just above the memory-card door. Once started, gently separate the back from the camera's body. BE CAREFUL OF THE RIBBONS. There are two ribbons that connect the camera back to the camera's body.

These are the main data ribbons that connect the back to the main camera body. Remove these by gently pulling down on the ribbon. Grab the ribbon as close as you can to the connector and gently pull down. The brown ribbon is the shortest and the blue ribbon is the longest. It is easier to disconnect the brown ribbon first.

The camera's back is completely separated from the main body. Next we will remove the screws securing the button panel we are trying to replace as well as a metal bracket that secures our LCD screen.

This is by far the hardest part, as the ribbons are very thin. I've found that it is easier to insert the blue ribbon first because it is longer. This will make it easier to insert the brown ribbon as you will have more room to work with.

I forgot to mention, that one of the best ways to ensure you don't have any leftover screws, is to scroll through the steps from beginning to end. This will remind you of some of the screws that are under the LCD screen and also the screws that are under the remote and microphone flaps.
 
Wow! I would rather send it to service. :) I'm impressed you got it right after.
 
Fantastic job, beautifully done. Thanks for going through the effort to put this together. Your instructions will also be useful for replacing the LCD screen.
 
I think it was out of warranty, but I was confident this would be an easy repair once I had the right part to replace.
 
phenomenal write up. I hope you don't mind but I linked your thread on Dyxum so that the members over there can come check it out here.

Additionally, I see that the part you replaced has the back wheel. If someone has back wheel issues this will also come in handy, as well as an LCD swap as already mentioned. Come to think of it there was a a77 being sold with a broken LCD and it would have been much cheaper to replace than I initially anticipated :-).

Anyways, thanks again. Very well written and explained.
 
Hi James:

The photos seem to be missing... can you possibly get them back?

Just today found this post.

Thanks for posting a great DIY!

Thank you for posting this.
 
Thanks for the great post I want to make an addition; you can slide eye piece up to remove, this was not clear, I almost broke plastic clips for nothing.

My joystick button was faulty, so I've removed the camera back cover. Unluckily it's impossible to disassemble the joystick without cutting the welded plastic ends. I cut 4 ends with a knife as seen at the photo below. Joystick contacts are covered with blue plastic sheets and got tiny holes. I sprayed inner area with WD-40 contact cleaner.

After re-assemble the joystick there is no need to glue the parts. Screws keep them together & tight. I also duck-taped the back area a few layers to support joystick clicks.

Now it works again properly.

Glad I can help.

A few months ago my LCD screen wasn't working because the ribbon connecting the screen to the main circuit board was worn out.

I referred back to this write up to help with the replacement.

Good of you to help yourself....kudos! Thanks for sharing!

James,

From the point of your disassembly, does it look like it would be difficult to remove the top cover assembly? My PASM knob fell of and it is necessary to replace the entire assembly to repair. Our local repair shop doesn't do Sony and I hate the idea of doing without the camera for two weeks to send it out for repair. Your project encourages me to think I could do the replacement myself.

Thanks,

Rick
 
Hey RTEX42,

I want to say yes, you could disassemble the rear panel to access the top menu knob (PASM).

During the disassembly, you are basically opening the camera in half and will see the access screws to free your PASM knob.

Hope that is helpful.

Thanks,

James
