But also I must resolder joints of all pins of the daughter board then it works.

My son’s Mindstorms brick is alive again. You information is excellent and precise, no too much, no too little. Excellent procedure.

Heating the solder connections on the capacitors did nothing. However, heating the ribbon cable with a heat gun did bring a few back to life. I hate these cheap ribbon cables. My guess is the glue that binds the conductive strips to the circuit board dries out and cracks over time. I’m hoping that the heat from the hot air blower can keep these things working for a while. Over time, I may have to make some custom connectors that can grip the ribbon cable more aggressively and stay connected.

Thanks for the tip.

If mindstorms does not allow it, download RobotC for mindstorms and install firmware, then reinstall firmware from original mindstorms.

Sun, 10 Jun 2012 18:57:16 +0000 http://blogs.wsd1.org/etr/?p=495#comment-424 I’ve solved this problem again and again. The capacitor has to fill up with energy after sitting for a while or having the batteries removed on occasion, because they discharged. Let it sit for maybe 15 minutes and it will be magically fixed. This works even when the image seems to be halfway down the screen, or garbled.

This has worked many times, and hope you have solved it without needing to disassemble your robot.

I will add : be carefull not to drop the little black button between the battery compartment and the mother board. This button seems to be the lithium battery detector.
I had to completly remove and put back the “C3″ capacitor.
Thank you again.

make sure to keep pressure on the capacitor when applying heat
if it sticks to the iron its a pain to get it back on the board

Thank you!! We were given a partial Mindstorm set, but the brick’s display didn’t work. Your instructions were spot-on and saved the day!

However, thanks to you, it now works! Thank you! And I did it, myself!
