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!

My Samsung LN-T4665F LCD TV is slow to start.

You have bad caps.on the power supply. They are under rated, 10volt insted of 16volt or more. Caps.run about $2-3 each. usualy takes 4-6 of them. Or replace the whole power supply.

Which Replacement Power Board for LNT4665F Samsung LCD TV?

Howdy,
It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thaks for using FIXYA, BIG IRISH.

Samsung 46" pink dots

I had a problem with the TV going on and off several times before "warming up" and then having pink dots. I would have to reboot to get rid of the dots. I called 1-800-SAMSUNG and reported that I had problems with the capacitors. That is what was causing the problems - cheap capacitors and Samsung is aware that this has caused many TV's to malfunction. My set was not under warranty but Samsung sent a technician across two state lines to fix my TV. As long as the problem is the capacitors Samsung will cover this service call 100%. My TV is fine now. BTW - capacitors which are sold in Radio Shack are not expensive. Why Samsung chose to put the cheapest Korean capacitors in their expensive TVs is a mystery.
So if your TV need warming up and has pink dots on the screen - call 1-800 -SAMSUNG and tell them your capacitors are malfunctioning.

No picture

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. If the picture does not return, then you have a more serious problem, that requires the attention of a TV repairman.

Samsung 19" LCD TV Freezes Image and Restarts Itself

I agree with Samsung. Tuner issues can be problematic. Since it's only a 19 incher, I'd just buy a new one!

Samsung LCD TV reboots repeatedly

Hi Bryan,These models are notorious for failing electrolytic capacitors in their Power Supplies, get the part number from the Power Supply Board and google it with +repair kits, there are many different kits available to tackle differing symptoms.Heres a massive 17 capacitor kit on Anazon: http://www.amazon.com/Samsung-LN-T4665F-Monitor-Capacitors-IP-301135A/dp/B00LU4UMW6

My Samsung LCD TV backlights will not stay on during rain or high humidity. Works perfectly otherwise. What could be the problem?

First thing I would do is get a humidity meter to see what point causes it to fail. This is important if you still have a warranty in effect. However, if you don't have a warranty, the most common cause of this issue is the inverter board.
