20 Most Recent Samsung UN40C5000 TV Questions & Answers

Because you have the extended warranty, I'd say take advantage of it and call a technician out to assess the problem on-site - they can then advise you on the best possible course of action to take from there if required. A third opinion by a service tech is valuable in matters such as this. (it could be any one of a number of things which cause this kind of issue in flat panel sets; the service verdict at the end of the assessment determines the most logical outcome based on how serious the problem is) Either way, you get to make the final decision; if you do choose to consult a tech, make doubly sure they are an authorized Samsung service agent and that they are willing to undertake the job under extended warranty. I would not advise trying to fix this one yourself, especially if an extended warranty is current and valid on it.

Just make sure that power is reaching the innards of the set. Does not appear so.
