Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Columns 11 to 28 & 51 to 68 don't light up - These are the columns controlled by IC's U5 and U7 but swapping these IC's for working ones doesn't make these columns light up. This suggests there's nothing wrong with the IC's themselves. The only other components that would have a direct effect on the...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Hi Thanks again much appreciated. I did have problems with R8 (I though I put the wrong component in, removed and then realised it was the correct one and put it back - doh). is there any way to test if this is the cause, repair or work around it? R10 is OK I think.

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Hi, Yes, swapped ICs around, same rows failed with exception of dimmer leds on column 57. Checked IC U1, soldering looks ok. I have attached photo of U1 and column 57.
Thanks

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Hi Andrew, thanks for coming back. I tried swapping ICs (it was already running via USB/computer). Unfortunately same issue exists, but I notice column 57 was lighting (not as quite as bright as the working rows though).
Cheers
Graham
