More than likely blown amp transistors on 1 or more channels. use an ohm meter to check resistance of the transistors.

My lavazza espresso point capsule machine has stayed plugged in and working for almost 2 years. Now it turns itself off after being on a short time or after brewing a few shots of espresso. If I turn it...


The only possibilities I see here are either the Plug Holder with Fuse Block which sometimes goes bad and periodically will shut down the unit. The other possibility is that the Electronic Card has gone bad. It over-heats and shuts down power.

Dell Dimension C521 power shuts off spontaneously seems the fan on the power supply isn't working.


Hello,

If the fan on your power supply is not turning then you need to replace the power supply as soon as possible. The machine is overheating and then shutting off. If the power supply is not replaced it can cause additional problems with the motherboard, cpu, and hard drive. Open your case and look on the power supply for your replacement parts number, check Ebay.com for a replacement. They are easy to replace, just a few screws and power plugs.

I hope this helps, if so please rate my solution.

Hi fdisc I feel quite sure your compressor is going straight to ground you need to get someone to check the comp, for its resistance and he or she will soon let you know for sure.

GE microwave won't turn off


Just checked the GE website. Had the same problem with my 5 year old microwave. GE website says to close and open the door quickly three times. First time I did this it didn't work. Second time I closed the door with some significant force and reopened it more quickly. Worked. Unplugged the microwave, plugged it back in, still fine.

Electrical - turn key on and electrical short


It sounds to me like it's time to replace the battery. How old is the battery (i.e. is it the original)? In my experience I find batteries tend to last 5 years and anything beyond that is just luck ;-) I think most parts stores will do a free battery test for you. Good luck.

Standard TV-Auto shut down


TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss.
Figure on replacing the flyback transformer.
However, my experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Another option is to wholesale replace the main board from an outfit like PTS Electronics at ptscorp.com.
Hope ya fix it!
