Top 20 Samsung LN-T4665F 46 in. LCD Television Questions & Answers

What do the power supply voltages look like?...are they all normal, specially the ones feeding the panel lamps

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!

Definitely a tcon board fault

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

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.

Check the breaker

What happens when you turn the TV on? Is there a clicking noise or popping sound?

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.

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.
