"turn on clicking problem which takes several minutes to eventually turn on,"
Now all you need to do is get the caps replaced. DO YOU DO YOUR OWN SOLDER WORK?
There are many discussions where we fix it ourselves.

Figure under 100 if we DIY.
I have an out of warranty Samsung 46' LCD that is having both of the problems discussed by many dissatisfied Samsung buyers. The picure distrotion problem started first about 6 weeks ago with horizontal and vertical lines distorting the left half of the picuture. After being on for awhile the picture would go back to perfect. We also noticed that if you physically tilted the screen to the left it sometimes solved the problem. It is now getting worse and often times does not clear up anymore. I've seen many people with this problem and they have mentioned possible fixes to: the T-CONN board, the LVDS Cable, a PCB board (?), and the Voltage Inverter. Not sure what any of these would cost to repair or which one is the likely source of the problem.
As for the turn on clicking problem which takes several minutes to eventually turn on, these appears to be a problem with the capacitors and is a widely known problem. I called Samsung to see if they would fix this at no costs because I had read that they had extended the warranty to repair this problem. I was told that they were repairing models manufactured between Oct. 2007 and June 2008. Guess what? -- I was out of luck because my set was manufactured in September 2007. Very frustrating and I am not a happy consumer. Any suggestions? The set was great when it was working and I would rather repair then buy a new one if the repair costs is not too expensive.
