Oh no buddy! Check if you're within the warranty. I think Samsungs usually have 3yrs, but stuff like that changes. TVs are so cheap nowadays due to margin/revenue erosion its usually less trouble/time and sometimes money than getting it repaired.
If you must get it repaired, big box electronic stores usually have vendor agreements where they will facilitate a warranty repair w/ a deposit(or fee) for shipping instead of working direct with Samsung. They'll wag the finger for not buying one of their fancy insurance policy plans, but at the end of the day they shouldn't refuse service(let them lecture/rant, but tell them you want mfg service anyway).
Thanks for the reply. Yea I thinks it's time to move on. I got lucky with the 46... Replaced 2 caps in the board and its been great. This 52 on the other hand nothing seems to appear damaged.
