Glad you fixed it but if power cord was bad the set should have no sound.

SOURCE: My Olevia LT37HVS 37' was working fine all day and turned to black screen.

It is either the fluorescent backlight source for the LCD panel or its associated power supply failing.

Have you tried unplugging overnight? Sometimes mine gets screen garbage and that clears it up. Of course, now it says "Auto Scan Required" every time I power up. Maybe I should've grabbed that after Xmas 32" at Fry's for $400.

If the power light stays on green, I would look tward a backlight issue. If you can see any image at all then the backlight controler or the backlights are bad. If there is nothing then if could be a power supply overheating or an inverter failure. More than likely as the unit heats up a failed solder connection is loosing contact causing the screen to go black.

It sounds like you have a power supply problem, this powers the inverter! Where you just replaced the inverter, we could assume it is good! Look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). The power supply can fail on some output and be good on others. Was the back light inverter new? If all else fails, see if you can return the back light inverter and get another! I hope this is helpful!!

SOURCE: JVC LT-32DS75SJ issue with HDMI

Try this

1. Turn ON TV
2. Connect PS3 to TV HDMI input
3. select TV HDMI input for PS3
4. turn OFF PS3 if it is ON
5. Press and hold the [I/O]Power button until the PS3 until you get the "HDMI Detected" message.

Also, this TV has a circuit that deactivates the HDMI if the rear cover is removed. It is possible the HDMI may have been turned OFF. This is reset in the service menu of the TV.

Why does the screen shut down after 1 sec while sound continues


It sounds like bad luck to me. You cannot change any settings on a TV by connecting a computer to it. In theory you can damage any monitor by setting the screen resolution of the computer higher than the monitors maximum res. The Sharp 26" has a resolution of 1366 x 768 (1080i) so (again in theory and I have never seen it happen) if you set the output to 1920 x 1024 (HD - 1080p) it can kill the screen. Perhaps this is what has happened. You will need to take it to a Sharp service centre.

Most likely you have a fault in the back light circuit. To verify this, turn on the set, when the screen goes black, take a bright flashlight and shine it on the screen. It may be easier to dim the lights in the room so that you can see the faint image on the screen. If you see the faint image, you indeed have a back light problem. You will need to get a diagnoses performed on the set to track down the problem

The set will need to be properly diagnosed to narrow down the problem. You could be looking at a bad inverter, bad CCFL lamp, fault in power supply or main board.

If the tv isn't fully shutting down. but just flashing on and off then it
sounds like a backlight supply fault.
All LCD screens have what can only be described as micro flouro lights inside the screen module.
it is possible that the power supply is faulty causing them to flash on and off every now and then. or the tubes themselves are damaged.
to confirm this..
Lay the tv down flat on its back and power up in a well lit room
get down close to the screen and look across it at a acute angle
now if the black screen looks like it is still displaying an image then it's definatley your backlights!

in which case it could be a simple fault in the power supply.
so if your feeling confident in yourself i can talk you through what to look for in the supply..but try this first and get back to me.

hope this helps,ben :-)

Vizio GV42L LCD TV screen black when turn TV on first time


If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
