Sharp LC46SB54U 46 in. LCD TV Logo
Posted on Mar 28, 2009

Our tv has a flashing power button. We cannot get it to stop flashing, and we cannot see anything on the screen.

    Our TV has the same problem. First the TV started turning off every 3 minutes. Now it just sits there with no picture and the power light is blinking. We unpluging it for a while but no joy. The power light just returns flashing as soon as we plug the TV back in.

    I have a viewsonic monitor with the same problem. My solution is only temporary. It seems that the power supply heats to a certain point at which the blinking begins. Points to a faulty solder or else a faulty transistor etc. If I turn off the power button and let it sit for 20 minutes, it seems to have cooled enough to come on and work when I press the power button on. Sometimes it will work for hours. If you were handy and find a way to cool it SAFELY with a heatsink, I wonder if it would function fine for a while. If you just uplug but leave the power button on, it doesn't seem to help. Have to turn it off and unplug and wait at least 20 minutes, but do experiment with one hour first.

Mitsubishi wd-73738 turns itself back on

Hi,

It sound like the remote is powering off the cable box but not the TV. The remote control may need to be reprogrammed to the TV. When you press power it may only power off the Cable box. At that point, try pressing the TV button on your remote and then Power. If it does not power off the tV after pressing the tV button, the remote may need to be reprogrammed to the tv. Cable companies usually have the codes needed to program their remotes to the TVs.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/laura_08254539050d64db

How do i unlock the region on my samsung bd-e5400 region free?

1. Ensure that there is no disk in the tray.

anything.

4. Press the eject button to open the tray. (The button is between the "Power"
and "TV Power" buttons at the top of the controller.)

5. Press the eject button to close the tray.

6. Wait while the player searches for a disk.

7. As soon as the "No Disk" message appears at the top left corner do the
following.

8. Press the REPEAT button - just above the TV channel selector at the bottom
right of the controller.

9. Enter 76884 on the number pad.

10. The region code "4" should appear at the top left corner of the
screen.(this just flashed on then off, so keep an eye on the screen)

11. Enter a "9" to make the player region free.

12. Power down and power up again.

13. Play a foreign DVD to verify the change.

Bush ID HDMI screen flashes red green blue, no buttons on the tv do anything. how do i stop this?

Just make a hard reset first. If it do not help you, you have to contact the authorised service center for Bush at your town. To make a hard reset, unplug the tV from AC mains power socket, wait for a while, and replug it.
