What is the difference between a black and beige capacitor? Looking on ebay currently. Unless you have a better suggestion. Thanks

Re: samsung ln46a540p2fxza red light blinking
One thing that is bizarre is I am getting an A/C voltage rating on the outside of 2 capacitors. Numbers cm808 and cm 807. They are reading an A/C voltage of 60 volts to the to of the capacitor

samsung ln46a540p2fxza red light blinking
Hello
I have a samsung ln46a540p2fxza and the red power light is blinking, every once in a while I hear the relay on the power supply click. the screen never lights up and I can not get to a menu on the screen. I have pulled the board and looked over the capacitors, none were bulging I still went ahead and replaced some of the normal ones that go bad (the 10v rated ones)
put everything back together and I am still having the same problem. what else can I do to troubleshoot this unit?
I have seen a post on the internet about a bad chip would this help?...
