Blinking power light

um u should turn your tv off for like 10 minutes , i think yourr tv is a internet tv so let it cool sometimes sony internet tvs freeze with black screen so try it out.
good luck :)

Turn the computer off all of the way by holding in the power button until it shuts off.

Turn it back on and immediately start tapping the F8 key. It should bring you to a menu that has an option for going to "Last Known Good Configuration". Choose that option and see if it boots up.

If pressing F8 doesn't bring you to the menu - you may need to run diagnostics on the computer. To get to the diagnostics, attempt to boot to the Boot Menu by pressing F11 or F12 at the boot screen and see if it gives you the option to run diagnostics.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Things to check: Are your display settings set to "native resolution" of your screen. The native resolution is the actual dimensions (in pixels) of your flat-panel screen.
Looks like the Dell E153FP 15" has a native resolution of 1024x768. In windows, go to your control panel, in display settings, and ensure the resolution is set to 1024x768.
If that does not work, you can try the "auto adjust" feature on the monitor. On many Dell monitors, you can get this by pressing and holding the + button (on the monitor). You'll see the words "auto-adjust" appear on the screen if this works. If that doesn't work, you may be able to find auto adjust by navigating the menues in your monitor's menu, which you can get to by pressing the "menu" button on your monitor (sometimes this looks like a little rectangle icon). If it's an alignment problem, this should fix it right away.
If neither of the above work, it's probably your video card. Make sure your video card drivers are the correct ones for your card and OS, and up to date. You can also mess with display options under Control Panel > Display, under the "settings" tab, and at the bottom click the "Advanced" button, and it will bring up the advanced settings for your videocard.
Good luck!

If it is your computer that is in hibernation then blinking on the monitor light is normal

Just bring your computer out of hibernation and the screen will come back to life too

The solution: hidden menu within the main menu itself. Hold the Menu button down while pressing Power to power on, and release power button only when the screen comes up, still holding the menu button. The menu will appear and there will now be a hidden selection, "Auto Color", printed in a red-on-black font at the bottom of the menu. Use the +/- buttons to access it, and press Menu. My green/yellow tint went away! Now my picture works great, and the setting lasts through Auto-Adjusts and Resets!

no stays completely blank. yes it is my pcs monitor

The problem is with front panel switches which needs to be replaced.

Not sure what happened as I had a whole message typed and lost it. Here I go again. I hope it doesn't post twice.

We have an Acer AL1715 monitor which started having this problem after a power surge. It was the only piece of equipment affected by the surge. I searched for an answer when it happened but got nowhere. I contacted Acer about this and they told me I would have to bring it to a tech to be looked at. Decided on a whim today to try Googling again and found this website and Q&As.

Though we didn't know what "Brunin" was nor saw an "F" change color, we did get into the Menu on the monitor and used the right and left arrows to see what was there. We decided to use "Reset" by highlighting it and pressing the "Menu" button for "Enter".

This appears to have solved the problem for us. The monitor is no longer toggling colored screens when idle nor when the computer is off.

Thank you for solving our problem. It has been very annoying for the user and anyone sitting across from her monitor during a meeting.

I seem to have found the solution (and the cause, perhaps?) for this problem!

I was having the EXACT same problem with a monitor I'm repairing for a friend. The capacitors on the power supply board were blown (CapXon capacitors, who'd've guessed), which was keeping it from powering up. After replacing the capacitors, the screen worked beautifully. But it had this weird yellow tint!

The strange part was that pure colors - red, green, blue - all appeared perfectly OK on screen. Curiously, the menus would show in the proper colors, except for one: the manual color adjustment menu, which illustrated "Blue" as a sort of off-green in the icon. Auto-Adjust would always fix the colors for a split second, then go back to yellow. Reset didn't fix it. Color reset didn't either. So, exactly the same problem as above.

The solution I found was hidden within the main menu itself, a sort of "easter egg". <b>Hold the Menu button down while pressing Power, and hold it down until the screen, and menu, appear</b>. There will now be a hidden selection, "Auto Color", printed in a red-on-black font at the bottom of the menu. Use the +/- buttons to access it, and press Menu. Voila! PERFECT COLOR! Perhaps this menu was accessed by accident, and calibrated to an incorrect color key. But now my picture works great, and the setting lasts through Auto-Adjusts and Resets!

Hope this helps some people, it sure saved my ****! ;)
