Yesterday I noticed my TR3 makes a click sound when the screen is opened all the way. Upon inspection I found the reason for this is one of the two bumpers on the rear of the hinges is missing. I’ve looked over the TR1 manual for the part number, but I’m unsure which one it is. Can anyone help here?

According to my TR5 service manual, the “bumpers” you’ve described is known as the “stopper.” The part number in question is 4-673-468-04 [ref.no. 213] and it is available for $4.80 at Sony DAPC. Hope this helps.

Thanks Ishii!

I just called and ordered it. 

Remember that is price for one piece. I sure do hope that is the part you really need. Good luck.

Got the part yesterday and it was the correct one. It’s tiny and I had to compare it with the other “stopper” to be sure which end is up before I snapped it into place. Now the lid is back to normal. 

Thanks again Ishii.

Brilliant. I’m glad it works out for you.  :D
