That won't be an issue if I can find an original part.  It shouldn't be much of an issue if I have to use an after-market part either.  It'll just be an incredible pain in the ass to barnacle it to the PCB.

I'm not too worried about the width and length.  It's the height.  

BTW, I emailed retrogamecave and while they were very nice they did not have any spare parts.

*double post*

ROHM Semiconductor actually responded to my query.  Unfortunately, it's not good news.  :cry:

Good afternoon Tim,

Unfortunately, we do not have any LB-202 LED displays in stock.

While not the exact same package dimensions (0.3 mm smaller width) or color variety, you may be interested in the following following:
http://www.rohm.com/products/opto_device/led_display/numeric/lb-302mf/
http://www.rohm.com/products/opto_device/led_display/numeric/lb-302vf/

Note, there is also a disparity in pin-out.

Product samples can be obtained from one of our distribution partners found at the following link:
http://service.stkcheck.com/?mfg=73164481-1808-449e-8974-2d558ac54708


It looks like the lb-302vf (red) is my best bet here.  Now I need to get a sample and figure out how to rewire it.

Yes, I know that.  You get full credit. :)  It was just in their email and I'm quoting it.

So after many, many months of waiting I finally received a replacement 7 segment dual LED display.  Tonight I put the kids in bed and plugged in the soldering iron.  Well after soldering the replacement LED to the PCB and reassembling the TG-CD...

SUCCESS!!!   :dance:

Here's what it looks like BEFORE;



And here is the AFTER;



I would like to say THANK YOU to Lost Monkey for sending me the LED display out of a busted CD unit he purchased.  Not only did he send it to me, but he sent it on his dime at zero cost to me!  THANK YOU Lost Monkey!

I can now enjoy my TG-CD in peace.  :D

Nice work!  Now that's a special looking LED right there!

It's a great feeling when you fix something yourself.  Thanks for sharing!

I bought a junk unit from a japanese seller for parts.  It looked like it had been taken apart years ago and forgotten about.  I needed the piece that slides along the worm gear.
