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!

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.

I have heard that this could be the TCON board. A tv I worked on had the same problem and reccomended the inverter board be replaced, that did not work so I would try the TCON board next.

it sounds like your back light inverter has gone. if its a led it could be built in on the power board. so check for bulging or leaking capacitors on the power board.
