I'm sorry to hear that you're having these issues.
I'd recommend having your unit inspected by a service technician. Unfortunately, it's difficult to diagnose these issues without actually being able to inspect the unit. You can either call 800-SAMSUNG or fill out the online service request form here:
since last month i have the problem with this tv, when i try to turn on: the lite is on but keep click/click/click wait about few mins to on. i had read these forum but not sure about changing the whole part or just the cap?
please can someone help me, cuz i'm getting confusing.
thank you so much
