    So I've ripped through the internet looking for information on this problem with my Samsung 51" LCD, and it seemed like a lot of people had it so I thought I'd talk about it here.

    Basically, when you turn the TV on, it cycles power on and off for about 15 minutes. Then, when it finally does come on, there are all these little pink and red dots on the screen. You have to shut it off and turn it back on, sometimes multiple times, until it finally starts to work.

    So, the quote I've received on getting this common problem fixed was anywhere between $200 - $1000 so I thought I'd do it myself, and then let you guys know about if you were having this same trouble too.

    I pulled the TV apart (just 2 dozen phillips screws) and took a look at the power supply (main, large board under a metal enclosure). There is an array of small array of electrolytic capacitors and 3 of them are popped. They all happen to be 1000uf but the ones that are popped at 10v. So, I pulled the board, desoldered the popped capacitors and dropped in 3 15v 1000uf replacements I pulled out of a computer power supply. I put everything back and buttoned it up and the TV works PERFECTLY now!

    I read that these capacitors were what the repairmen were working on when they had them repaired. I just wanted to let anyone with this same problem know how easy it is to do yourself.
