I bought a 12v 6a power supply from 12vAdapters.com, mostly because this guy has a listing on ebay with my tvs picture and model number. However after seeing other complaints on this site about this guys business, I feel I should report my findings as its very dangerous what he's doing. Let me explain,
My tvs model is Sharp LC-20B6U-SM, he's got this listed on ebay with the picture of it saying his power supply is the proper one for a replacement for this tv. IT IS NOT. The OEM Sharp power supply is 12v6.6a not 12v6a. That's over a half an amp more then his power supply can safely handle! Not to mention the OEM power supply is about 3 to 4 times the size of his physically. Basically after purchasing this item yes it did work, powered up my tv, ran it. His power supply was too hot to touch with in an hour and smelled smoky. I used it sitting on top of a metal cake pan (for safety) for about 45 days before it finally melted the outside plastic housing and burnt up and failed. Why did it fail you may ask? The extra .6a is like driving a car 110mph that's only rated for top speed of 80mph safely; eventually it's going to fail.
I contacted him to let him know his power supply was getting very hot after 1 week of owning it, he declined to return my money, Yet he still has ads on ebay for model Sharp LC-20B6U-SM. I Since then purchased a new 12v 8a power supply that more then covers my tvs 6.6a requirement and it only gets luke warm like it should after an hours use.
I want buyers to know they need GOOD homeowners insurance or rental insurance if you use this guys products cause your likely going to need it when the fire department puts out the flames.
