If your tv is within the one year warranty period then call 1-800-Samsung for warranty repair. Look at your tv purchase receipt for the Purchase Date. You have one year from the date of purchase to get warranty repair.

SOURCE: T.V Problem

I think your main power supply is failing. If you want to avoid a long interruption or fix the problem now, read my stock response paste below:
If it's failing to turn on reliably, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core (no laminations as with a line-frequency part) transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.

Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.

If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself but it will likely have the same problem eventually unless they have altered the design.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.

Not familiar with this particular model of samsung LED TV, but ghosting and shadowing are usually an accepted manufacturer's defect.

If you're still under warranty or within 30 days of purchase, contact the company that sold you the TV or Samsung warranty department.

If you're out of warranty and you don't wish to deal with this, contact a TV repair shop. They will most likely tell you that it's not worth repairing and recommend you purchase a new TV.

I have a problem with the on off switch on my 40


Hi There

This is most definitely bad capacitors in the power supply, Take the back of and look for capacitors that are domed shaped on top,
Replace them with a higher voltage rating but the UF NEEDS TO BE THE SAME IE... 10V 1000UF CHANGE TO 35V 1000UF
This will cure your fault
