What is a good source for getting capacitors. I need a Series LY, 150uF, 450wv, +105 degree C. It is from the power supply of an LCD TV. It looks OK except that the end is slightly crowned and can be pushed in. A friend gave me the TV and the first time I turned it on it smoked a bit from the vent next to the power supply. A visual inspection of all the boards show no burn or heat marks. This capacitor is about 1 5/8 by 7/8 dia. A small 10uF cap has a slight bulge on top, unlike similar caps. When turned on there is a dim picture on the screen but only lasts about 10 seconds even after the smoke event. How close do the specifications have to be.
