Mlt386x power supply

Thanks for you help with the fuse. I unscrewed the power supply board and when i looked on the underside i noticed a small scorch mark along the circuit path, it's marked ck23. i checked for power on some of the diodes around the fuse but so far i get no voltage hits aside from when i check the fuse. do you think that burn mark could be why my tv isnt getting any power beyond the fuse?

My akai tv model lct3785ta will not turn on


Ok.. What is the status of the power LED at the front. Does it blink, change color a few seconds after its turned on? Do you notice any clicking noise from the set?

Please provide this info so that we can continue with the diagnosis.

MLT386X power supply


Hi wanagetdrunk, Nice handle is that a question or a statement? To test the fuse with a voltage meter you will need to test each end of the fuse and make sure the voltage is the same on both ends, in other words you want to make sure the voltage is passing through the fuse. If you have a multimeter set it to ohm's and measure across the fuse,if the fuse is good it will read 0. Let me know if this helps and please rate this solution. lone99star
