Try a hard restart, which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics, to a certain extent.

MY SAMSUNG TV LNT4665FX DIDN'T START PROPERLY AND TAKES 10 TO 15 MINUTES


I'm willing to bet you have faulty capacitors in the power supply. You can either have the individual capacitors replaced(cheap fix) or replace the power supply board. This is my best guest as this model is known for this problem. If you don't feel comfortable in opening up your set, get a professional to look it over

Samsung LNT-4665F won't power up properly


There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Samsung power on off problem


The power supply is probably getting weak and ready to fail. Having a qualified technician repair it now would probably be less expensive than waiting until it fails completely.

Samsung LNT-4665F takes several minutes to turn on


This could be the power supply problem, or the main board. You need technician to fine out what is going on.

Have same tv and same problem samsung lnt4665f


We have the same problem with our 46" Samsung LCD Tv LNT-4665F. It's only 2 years old and unfortunately it's out of warranty too. Our tv would not power on and just does this clicking sound. We called to get it serviced and we will need to pay $95 to have somebody comeout and diagnose the problem or we bring it to the shop and pay $50 to diagnose the problem. we've never had any problem with our SONY TVs. we regret buying Samsung!
