LG washing machine will not spin just makes a click sound an buzzes? any help?


any error codes, make and model no. would help.
some swear that unplugging and waiting a moment and plugging back in will reset. some say, doing same and holding in start button while unplugged for 10 seconds will reset. not sure about those, but pretty easy to try.

Check the Y-sustain drive board. If it is faulty /shorted, this kind of fault can occur. Short circuit protection circuit inside the TV energizes, and switches it OFF, to prevent further damages, is now going on. Will be best to contact any service technician. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts. Check the site in 'Mosaic' view. It will make search easy.

I have a new lg window air conditioner that is buzzing loudly when the compressor turns on. as soon as the compressor shuts off it stops buzzing. the buzzing noise also sounds like a playing card attached...


sounds as though the contactor is not pulling in tightly. but it also spunds as though the fan or fans might be hitting some thing . check them out shut the unit down and spin the fans and see if you hear something. if not then it could well be a contator .. But as I think a bit more could be lose fan, or compressor is not setting on it isloator bushings .

Hi, I own a 50 inches plasma LG tv (the model is 50pj550) for only 2 weeks and it has started giving me 5 green dotted lines 9consisting of green pixels), from top right corner to bottown left corner....


Sorry to lay some bad news on you.........

It sounds like your set has had defective silk screening during the manufacturing process.

The lines in a plasma set are laid out using a silk screen process, the defects (if any) are burned out by laser, then the surface is sealed to protect the lines with a vacuum coating process. Your set sounds like it had a manufacturing defect that quality control somehow missed...it happens!

The good news is that since your set is brand new, you should be able to exchange it. Don't delay!
