Still trying to fix my kvx-370...
 

Recapped the set, and cleaned some traces. Set turns on, but now displays black and white picture, overlaid with red, green and blue garbage in the picture.

How can I fix this?

Hello Devicemodder, I have 9 working (which arrived non working except that stupid deceptive red light) watchcubes. For your benefit I repeat that an ultrasonic cleaner is a good tool investment for this endeavor. Those corrupted vias on the watchcube stymie the efforts of repair/ refurbish.

You are oh so very close though. Even acomplishing the clock display proves your patience for the matter. All of my watchcubes arrived in stupid corrosion. You are near the finish line.

If the any buttons are not responding , please mentioned in available detail.

If you find this too frustrating, what is your location? I am in southern california and may be able to finish the repair if you determine it to be beyond your patience or capability. You are so close!!!

All buttons work. I recently got an ultrasonic cleaner, and I'll give that a go. Should I remove any components first? Also, I am located in Toronto canada.
