I'm hoping to bypass the flasher control on a Czjutai Christmas lights power supply so that the lights stay solid on, without having to press the mode switch each time the lights are powered up. I only want the lights to remain solid on, and do not need to use any of the flashing functions.

I came across this thread from 2020 that asks (and solves) exactly the same question:

However, when I opened up my power supply, the PCB layout was different:

Any advice on what I should bridge to keep the lights solidly on?

Thank you in advance for any help
 
In short, you can't. The two wire strings need AC power to turn on both halves of the string.
Where are you based?
 
I have a number of unused controllers like these but with memories so that they stay on whatever function you select. Would happily send 1 out for the price of freight.
As Skymaster said this style can't be hacked to make them stay on. The polarity of the lights gets toggled. On the old school incand style controllers that had 3 or more wires from the controller out to the lights they could be hacked.
