Jeremy,

What in the world is the hold up here. Grab household lamps, anything with a light bulb / plug and plug them in.

Great to hear :waycool:.

My thoughts exactly. I've got (seriously) at least 20 strings of lights in my direct line of sight right now just sitting around looking to be plugged in to something.

(My wife has "concerns" regarding this situation but our therapist says we need to "work through it." :laughing:)

Yeah, I am ok. what I did to fix the problem was took the big chip out right above the microprocessor and then Put it back in.. with the POWER OFF.. of course! And then plugged it back in tried the hardware utility and it is now working!.. im working on labeling the channels now!.. thanks for your help.. this was new to me since ive not built one i ordered my first 8 two years ago prebuilt.

Do you have any idea though why 1 channel wouldn't work?

Check the soldering on the white IC that controls that channel. (I assume you can identify the channel that isn't working.)

If that doesn't help, check the soldering on the chip on that side of the board. (The "medium" sized one.) You might have missed a pin.

Edit: If only ONE or TWO channels aren't working, you should work your way back from the output side to the middle. Check the soldering on the spade lugs, triacs, resistor, etc for the inop channel(s) and work back towards the center. (Follow the traces on the board.)

Yes: remove it from the enclosure.

Don't feel bad - we've all been there. (At least I have.)

You can leave the power leads connected (******** BUT UNPLUG IT FROM THE POWER SOURCE!!!! ********) and just unscrew the heat sinks from the case and then from the triacs. Then flip the board over while the lines are still attached.

It's not THAT bad...


Edit: Added warning to unplug unit (for anyone reading this thread in the future.).

With the main power off.. right? This has definately been a learning procedure.. lesson learned #1 never attempt to solder at 2 AM..enough said there.

I've done some pretty stupid things earlier than that.

But that's probably a good "rule of thumb." :P

Make sure you didn't mount the white IC on that channel upside down while you're at it.

Well, I'm back to working on my "North Poles" so I'll leave you to it.

BTW - don't forget to tell us what was causing the light to be "dim" originally.

It might help someone out in the future.
