Nothing to do with the remote! - It's either the main PCB or the power board depending on exact version of model - how old is it?
Mine is doing the same it's just over 2yrs old.
I would contact your local samsung authorised repairers and get samsung to pay for the replacement part as I will be doing tomorrow.

Try renewing the batteries in the remote control. It worked for me.

1. the motherboard might be bad and you will need to replace it. 2. or The power supply is bad
Chances are if its making clicks the power supply is bad and you will need to replace it. Which makes sense because constantly powering the tv on and off will damage the power supply or possibly short out your motherboard. These things usually cost about 200 bucks to fix at a local tv repair store.

Samsung LCD HD TV Model # LN-S4041D > 4 years old - working fine until today - While watching TV, I heard 2 loud beeps and the TV image was lost - initially frozen pixels and some moments later .......


Th clicking is from the power relay. You will have to open it up, the first place to look will be the power supply module, look to see if it has any bad caps with leaking/bulging tops first, caps can look OK but can be bad due to high ESR.

DescribMy Samsung TV Le40R7 is just clicking. It turns on and turns off repeteably. If I'm lucky I have picture for about 5 secondse your TV Combo Problem now it wont even turn on at all


This unfortunately is a repair job as there is very little you can do with these sets. The reason the set is clicking on and off is due to the protection circuitry activating , sounds like you could have a problem with the line stage which is the section that drives the LOPTX(flyback transformer) that drives the Horizontal and the high voltage output on this set.

Since your tv is a new model it will be IN Warranty. Call 1-800-Samsung and they will set up a service call and send your ticket to a Qualified ASC in your area. Ask if they can send a Samsung Field Engineer to repair your tv. They are nmch more highly trained and you will have a better repair experience.
