Dead Control Screen and Light out on Fridge Side (FIXED)

Ordered a NEW 5304527931 and installed 2 Days ago. Looks and works perfectly. And it took a while to plug in the LED, as I had to use a Hemostat to squeeze on the wire end that would open the mouth of the plug to fit the LED. But now I have a beautiful Dispay with Degrees, and a light that goes on when using ICE or Water. I think someone must have had this area open before as the LED wasn't plugged in. All good, and all perfect.

Finally got up to my Daughers and measured the Voltage of the Red and Black, and it was 15.73 Volts, so that was good. Then I installed the eBay purchase of control board 5304527931, that looks like mine, but bought using that plastic case # on the back...8076419. So I have replaced the ice chute, now drops ice or water, and tongue springs back into position. And control panel NOW lights up, where as last 2 weeks has been black. Although you can see the missing parts of the LED #'s. But fantastic... Just to see the screen lit, and ice and water on demand working again. I guess instead of buying a $27 8076419 control board, I should invest a little more in a 5304527931. Thanks for the help. Also, still not sure why control board has that LED strip, but no wires going to it, so that when in use, would light up the water cup or container... But fantastic day, here....

Haven't checked for 12 Volts DC at the J4 Red and Black, as the Refrigerator in Question is 40 miles from me, and I always like to have a few ideas in line before taking the drive. Will get back with voltage asap.

Added 3 shots of under the black plastic on the control panel, showing any numbers visible. Imagine only one Square #2 Screw head holding black plastic on. really easy. Funny, when I search online for the Frigidaire 242209710 control board, I see 85% of them are attached to another larger white board. Must be a ton of different boards, thru the years.

I was working on the ICE Chute as the spring had broke to return the little hang down flap and I made the mistake (I guess) of reattaching the control panel without unplugging the Refrigerator. I heard a DING or some sort of audible tone, and after all together, the screen is dead, and the right side LIGHTS are out. The freezer light are ok, and I replaced the bulbs on right side but still dead. And the freezer and fridge are still keeping cold, I bought two thermometers to be able to tell. I have replaced the control panel and the ice maker chute with eBay purchases and still dead screen, and dead lights on fridge side. You think the bottom control board? In searching the web I see two different videos of taking off the control panel, and when they do , there are only 3 plugs going into it. Mine had 4? Maybe before we moved into Condo, it had some work done?? My image is the bottom. Maybe different model?? But will know more when I get back to the frig and take a reading at that J4 3 wire plug for voltage. Model # picture added. TY

Added a closeup picture of control board plastic back. It had a number on it of 8076419, not sure how it compares to the number 5304527931, I bought one using the number 8076419.... might have been a mistake
