Have TV Questions? Ask a TV Technician
Hello, Sorry you're having problems.
If you use the original Sceptre remote and press MENU, or change the Input- can you see the MENU and Input indicators show on the screen?
Also, roughly how old is the set?
Than how were you able to change the Input over to VGA?
We need to know if the TV's native functions show up on the screen. Press any of the buttons on the TV itself and tell me if they appear (Input, MENU, Volume, etc.).
On the side of the TV are your buttons. Source is (S). Press it. What exactly do you see on your screen?
So NONE of the TV's function buttons will even display their functions on the screen correct?
That indicates the TV has a hardware failure. There is nothing within the normal operation of the set that will prevent these buttons from displaying their function on the screen. So the issue is not a connection/setting related one, but rather that the Sceptre TV has an internal failure- generally the Mainboard if the Sceptre logo appears and screen goes black. Where did you get the set from and when did this problem occur?
Okay, it requires repairs. Is this something you're looking to fix yourself? If so, I will need you to check some things.
AFTER the screen goes black, shine a flashlight at a 45 degree angle up against the screen and look VERY closely. Press MENU and let me know if there is a shadowy image of the MENU barely visible.
We need to know if the screen is still "Backlit" then- meaning slightly lighter than if the set were off. Shut the lights out or dim the lights in the room and see if the screen is still slightly lit when it goes black.
Okay, these are not consistent results then. If the screen were black as if it were off- then the image would be visible with a flashlight.
If the image were not visible with a flashlight, then the screen would be backlit.
So unless you have multiple failures in the set, then one of the results is not correct.
Okay and just to clarify- the sound stays running during this entire time when there is a source connected, correct?
Okay, at the very least your power supply/Inverter board is faulty, since it's what provides the lighting to your screen and that part is available below for $85 and change:
At worst your Power supply and your Mainboard have failed and that board is just below $80 at the following link:
Given the cost of parts alone to repair the set are going to be close to $150 and the TV can be replaced with a brand new 32" Vizio LED (which is built better than a Sceptre) for $200- I would personally consider putting that same money towards replacement of the set versus repairs.
Other than that, I'm sorry for the bad news here and wish there were a quick fix.
If you need further assistance let me know. Before you go, PLEASE DO click at least a 3 STAR RATING, at the top of your screen. That is how I am credited for my efforts by the site.
Do you need further assistance with this?
