I have a Sceptre X46BV-1080P and all of a sudden the sound stopped working. I only use HDMI1 and HDMI2 ports. I've done power cycles and the first thing I checked was if the tv was on mute (it wasn't). I can see the bar on screen go up and down when I hit the volume buttons on the remote, but there is absolutely no sound. What should I do next?
I have a similar prollem. When TV is working fine, sometimes the sound CUTS OUT (GOES SILENT). Turns out, if I merely touch or wiggle the headphone jack, the sound returns. Try touching any of the input/output jacks. Must be a short or loose wire. If I'm using headphones I just skake the cable and it is fixed, til next time. I gotta do something about this prollum.
I think that you missed to check its speakers. Check it. If they are found OK, the audio output section circuit should be troubleshooted.

What is happening is the internal "Fault" that is causing the Protection Circuitry , to detect the problem and attempt to shut down the set, keeps restarting the set, because as soon as it shuts down, the "Faulty" component(s) cool down?, and the "Fault" ostensibly "Clears" so the PSU starts up again, only for the component(s) to heat up, whatever, again and fail, so it shuts down, and if left unattended, this would continue on until the part eventually failed. As related this is called a "Hic-upping Power Supply". Any fault that involves the power supply is usually quite serious, and needs a professional, usually, unless one is familiar with servicing current day, televisions.
And in my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center. Now, this point is very important for a good result, Always contact, their "Local" or a, "Head Office" Sceptre, in your case. Ask them, for a referral to an authorised servicing center, where you ask for a "Quote". Now, when you get the information you want, then you can decide as to repair of replacement.
The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free. There are many, many, many reasons that display this symptom, one must work through the troubleshooting steps to isolate and identify, the Cause and repair that and any damage done.

Hi,
To start the conversation, i would like you to ON the TV and take the remote to a different room. Then observe and see, if there is an issue with the volume. If not, then this is a case of faulty remote. I have seen few times when a faulty remote could send irregular signals and cause to volume to react in an unusual behavior. If the problem remains the same, then this is an internal failure and needs repair. You need to open the TV and check different components. In most cases, it is often faulty main board, however we cannot jump to any conclusion without testing the components. If the remote is not at fault, either you could call a tech or if you have prior experience of working on these sets, have electrical equipment and would be able to carry the repair, revert and i would be able to provide few more details and could possible provide you with a link to buy service manual which would be helpful.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
