LN52A750 (52" LCD) clicks on & off continuously

by Mogly406 - 5/4/10 5:26 AM

Hello - I have an LN52A750 (LN52A750R1FXZA manufactured 9/08) that has the dreaded power on issue where it constantly cycles by clicking on and off, but never boots up. I have read that many other people on this forum have the same issue with the problem being blown/leaking cap's on the main power board. The first thing I did was call Samsung, but they are unwilling to honor any type of repair since my tv is a few months out of warranty (purchased 1/09), regardless of the fact that this is a widespread problem. Anyway, there are tons of diy capacitor replacement for these Samsung tv's on the web, so I figured I'd give it a shot. I took the back cover off of my tv last night, but in my case, all of the cap's look good (no buldging at all, tops still flat, no evidence of leaking). Could this still possibly be a cap issue even though they look good? When my tv failed, it was sudden. Up to yesterday it has never had a problem. Yesterday we watched a show, turned it off for an hour or so, and then tried to turn it on again and the problem started. It has not powered up since and I've let it do its clicking cycle for up to 15 minutes numerous times. It seems others have had more of a gradual failure with it powering up after clicking for 5 minutes or so and getting worse over a period of weeks. Do this indicate mine being a different problem? Any advice would be greatly appreciated as I don't have hundreds of dollars to spend for a tech repair. Thanks, Jay.
