This is exactly the same issue that I had, except in my case the last 5 digits were flashing as opposed to just three in your case. I contacted Elksmaker by email at email@example.com and they were able to diagnose the fault to being an issue with the LED board under the first flashing set of digits.
To confirm the issue you just need to remove the bottom plate and bypass the first flashing board to see if the rest of the LED's past the initial flashing board return to normal.
They sent me a replacement board free of charge. I replaced the board and all the digits returned to their normal mode.
You just need to remove the 4 screws holding the bottom on. Remove the bottom plate carefully as the lead from the LED boards to the controller board mounted on the bottom is very short. Disconnect this lead and the bottom plate is now free.
Replace the controller board,.
You will then need to remove the two screws holding the bland end plate on as you substitute the replacement end with the mounted switch board on this end.
My clock has done the same thing. Started out by always running really fast, the one of the digits the color started changing/going out. Now the last 3 digits do not even work. They are dead. Pretty said, for the price we paid for these that they have died so fast...
Thanks for your input. I did that and hooked the clock back up to the computer and when I hit the "start" button the clock synced to the computer clock and everything was fine. from now on I will make it a habit of doing this once a month just to keep the time close to "real time" I also thought I would change the color scheme to match the season, i.e.: reds and greens for christmastime.
Hello watch fans
I have now installed the software directly on the desktop.
It works fine now.
I had to find out that the clock works exactly with the software on the PC.
As soon as the clock is connected to the external power supply, it runs too fast !!
Per day, the clock runs about 16 seconds too fast.
Is there in software update?
I will test the clock for a long time on the external power supply.
