Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.

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. But you will have the same problem in a couple of years. Best bet is to have the bad caps. replaced with the right voltage rateing,and you will not have to worry about it happening again. New power supply is...

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.

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.

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.

Please check the power supply board, if there is any Pup-Up electrolytic capacitors, please replace them.

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

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

Definitely a tcon board fault

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.

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!

Contact the authorized service center. Your TV need a through checkup.
