New Sceptre 37" LCD TV does not turn on

I just received a new Sceptre 37" 720p LCD TV and after taking it out of the box and connecting the power cord, the indicator light turns a solid blue but the screen does not turn on. I tried changing the power cord, plugging in av and component cables, but nothing works. Unplugging it for a minute, replugging it, and waiting for 30 seconds to turn on like the Sceptre tech said does not work. The blue indicator light does not turn red to go into standby. Pressing every button on the tv and remote produces no results. What is the problem?

    Everything was working fine until I plugged an HDMI cable into the HDMI port on the back. The blue light came on, the picture does not display, and nothing changes no matter which buttons I press. I am only able to get rid of the blue light if I unplug the Sceptre. Once I plug it back in, the blue light comes back. I wonder if there is a reset process I can use?

    It will show the red "standby" light at the bottom left, but no blue "on" light, nor any picture whatsoeverwhen pressing the standby button on both the remote and the actual television panel. I have tried turning it completely off at the base, unplugging from the wall socket, waiting five minutes, then re-plugging into the wall and switching on at the base. Red "standby" light comes on to indicate power to the set, but standby button on the remote and on the tv panel itself have no effect. Help please.

I just got a 42" komodo by Sceptre, same problem, except "SCEPTRE" showed on the screen. I was sent a USB key program to insert in the service slot in the back and it reflashes the bios. This is old news for you but maybe new for someone?

Normally the a-v cables are color coded the white goes with white the red goes with red and yellow goes with the yellow and when putting it in the dvd player if applicable it should be the same way did your tv come with a manual showing you how to hook it up

REPLACED POWER BOARD TV TURNS ON DISPLAYS PHILIPS AND SHUTS OFF ,BUT LIGHT BLUE INDICATOR LIGHT STAYS ON
If no signal (whatever the reason) most sets with a solid blue screen will shortly shut off.

A few things to try first:

Unplug set, a box if used, a receiver if you have it in line---wait a while and plug each back and wait to see if they reboot and restore signal.

Also look to see if you can get the set to a video input before it shuts off---A DVD etc should be connected and on when you try that.

Sceptre LCD TV power come on, but there is no picture or sound.
There are two easy fixes you can try. Both require you to take the back panel off. If you are not comfortable doing this, take it to a repair shop.
UNPLUG IT.
Place the TV face down on a soft/solid surface.
After you get the back panel off, there are three silver boxes. There are white and black wires leading from the off switch to the top silver box. Take the cover off that box.
Inside is a ceramic fuse. Test that fuse. If it is blown, your local electronics shop can find a replacement.
If not, disconnect the white and black wires from the PC board. Remove the 6 screws holding it in place.
Look for scorch marks under the board.
Cut a thick piece of plastic and tape id down over the scorch marks.
Re-attach the board with the six screws and re-connect the black and white wires.

Turn the power switch to the OFF position and plug in the TV.
Turn on the power switch while WATCHING the board you just removed.
If you hear a sizzle, turn off the switch and get a thicker piece of plasic.
If not, the TV should come back on.
Re-assemble the silver box and put the back on.

Hope this helps.

No picture and no sound
If you have a blue screen on tv, try changing source with the remote control, and check connection cable to source.


Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem on dvd with no receiver box connected.

If the TV goes off completely, then is usually a faulty power board.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.
