How do I switch from strobe to constant light?

they have computer boards in them. it would be cheaper to replace them. your question is not cear

Make sure you're putting in the correct wattage.

THIS FLASHLIGHT SHOULD HAVE THREE DIFFERENT LIGHTS WHEN YOU ACTIVE THE SWITCH TO TURN IT ON.FIRST IS THE BRIGHT,SECOND IS THE LOWER BRIGHT AND THE THIRD IS THE STROBE.YOU SHOULD BE ABLE TO ACTIVATE ALL THREE FUNCTIONS OF THE LIGHT BY PUSHING THE SWITCH.HOPE THIS WORKS.IF THIS DOESNT WORK THEN THERE IS SOMETHING WRONG WITH THE SWITCH.

how do you know theres power to the unit if theirs no strobe light pitch adjuster light & the platter doesn't spin?
the power comes in & to the transformer first,then through the strobe switch, the transformer is what blows when you short the target light out.....i've seen this many a time when people try & change the target lights to blue neon.

Mine did the same thing so in desperation before disposing of it I did the following and it worked. I turned it on and while strobing, I locked it in place wanting to run the battery completely dead before recharging. It ran that way for about 45 seconds, it beeped and started working correctly. It may only be temporary, but worth a try.

What does this microlight used for? You ownly have a momentary switch? stewbison

When I turn on My RCA L40fhd41 40" television, the LCD screen constantly blinks on and off like a strobe light. The power light stays on constantly, but the screen continues to blink

I have DMtech 20" with intergrated DVD and had the same problem- blue light lit on power switch but no response on power up.
I noticed that when the power cord was unplugged from the back of the TV the green LED on the power supply would brighten and consequently dim when plugged back in. Sometimes the blue light on the power switch would strobe very quickly but you had to look carfully for this.
I repeatedly unplugged the DIN type power plug from the back of the TV untill the green light on the power supply stayed a constant bright and there was no strobing on the blue light on the front of the TV, when I powered the TV on at this point the button worked again and the tv powered up with the silly tune then life in the screen. I did have to do this a good few times (I'm tenacious) but it did work!!!!!
Hope this helps someone else, cheers.
