IMAG3233.jpg IMAG3236.jpg IMAG3233.jpg IMAG3233.jpg IMAG3236.jpg I have some garden LED lights controlled by a timer plug that turn on in the “all” mode (flashing, slow dim, constant and so on). How can the circuit be altered so that the only mode is constant?

You'd probably have to bypass the processor (that multi-legged component half way across the pcb) and re-configure connections to the 5 wires feeding the LED array. Without knowing the specs of either the processor or array the chances of success are slim :(.

You should be able to jump collector to emitter on the transistors like this.

You could then eliminate this trace to kill supply voltage to the processor.

Sorry second step is not completely right. De-solder current limiting resister lead from circled pad and re-solder to where I've pointed to as well as cutting this trace.

So from here to here.

While i don't have an understanding of what a resister, processor, transmitter etc, would any of you kind souls please advise me how i can bypass the 8 modes to keep the lights on static for these two circuit boards?
