Won't power on


Chances are it is the Power Supply. It is a Megmeet MLT386X which is hard to find, but sometimes IS available on ebay. There are places that will repair the old one advertising on ebay as well. If you remove the covers running across the heat sinks and see that the capacitors are bulging, the repairs are within the capability of anyone who knows how to use a soldering iron.
If you are handy with a soldering iron, LCDalternatives sells a kit with ALL electrolytic capacitors prone to fail for $15.95 plus shipping. I bought the kit and fixed mine. It took a couple of hours to unsolder and replace the capacitors. Powered up and has run for last two years with no problems.

wont turn on when u press on off button it just goes click click clickc


Go to EBAY and look up a capacitor repair kit for your model kit. They cost $20 to $30. This is to fix the power supply board which is the middle board. Be sure to note polarity of the capacitors you replace. There is a positive and a negative on them and that must be observed. Use a magic marker and mark the top of each cap as you replace it. Replace all caps supplied in the kit even if old ones don't look puffed out. This should fix your power supply. I did this on a friend's set over a year ago and the power supply is still ok.

my Samsung flat screen tv won't turn on and it keeps clicking - it keeps trying to turn on but then starts clicking again.


There's a couple transistors on the Power Supply board that are probably bad. On mine, the solder joint was bad on the bottom side of the board that pointed me at those transistors in particular. Part number is FQPF9N50C. Also, you could get a refurb or new power supply board of ebay or send your board in for service (also on ebay).Or there's a "repair kit" you can get that contains 4 transistors and a couple caps I think. If you are an electronics junky and like soldering stuff, that would be the way to go... I just ordered the two transistors off ebay for like $6.

How do I obtain and replace the C3 capacitor on the clock board of a Model SCE30600 Range?


C3 capacitor rated for 68 µF- 35 Volts the closest radial capacitor from RadioShack is P/N 272-1015 (47µF-40 Volts). Pay attention to the position of the "white arrow" on the capacitor when replace. A little patience, a soldering iron and less than $1.50. Your range will be as good as new.Bonne Chance!
