Turning on tv

You can try.. turn on the monitor if it just shows the white screen then turn it off then turn on instantly. Even then, if the screen continues to be white (blank) then turn off the screen, unplug the monitor then again plug it after a minute and check.

Try firmware update on the Polaroid TV for appropriate model

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.

I have LG M2062DL with white screen appears V3.23.0

did you changed frequency of that monitor? if it is out of factory setting that could be the problem, try to connect it again as secondary and set Hz to default, if that does n't work try same settings on both monitors? i have connected two monitors i had same problems , my secondary monitor was clone for tv if you are using secondary monitor for clone to ty (with s-video or whateever) if tv is old it must be 60HZ 800x600...

sound like the inverter circuit board problem. check & replace back same part# inverter circuit board. hopefully could help!!

Honestly, that sounds like one of two things happened. Either the resolution of your computer video card changed or (I'm not sure with your specific TV) the TV's resolution changed.
If through the TV menus you can adjust PC resolution, I would try changing the resolutions. In the LG 47LB5DF TV, press Menu, then go to Picture, then go down to Screen. On the screen menu, you will see Resolution, Position, Size, Phase, and Reset. First try adjusting the Resolution to some of the options you see. If that doesn't work, try to reset the screen settings.
If adjusting those settings on your TV does not help, then you will have to change the resolution through the computer. Try connecting a monitor to the computer. If you get a picture through the monitor, on the desktop right click and select Properties. If using XP go to the setting tab, if using Vista/7, select Display Settings. Lower the resolution to something you think the TV will be able to handle, then connect the PC to the TV again. If you are using an HDMI connection to the TV, you may have to turn off the computer, connect the cable, then turn the computer back on with the TV on the correct input.
If the monitor doesn't show the picture or if you don't have another monitor, you can try adjusting the picture in safe mode, by pressing F8 after you press the power button, before you see the Windows loading screen. Press if multiple times if necessary. You should see a screen that gives you a few startup options. Select Safe Mode. After Windows boots up, you should still see the screen as the resolution would have been reduced. From there try changing your display settings.
Hopefully that info has helped. I noticed that you asked this question 2yrs ago, so I hope you have already figured out how to fix your problem. I simply wished to post this in case it would help you or anyone else had a similar problem. Good luck and take care.

my 55613 tv wont turn on just blinking green light

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.


1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

hope this may help;

Have you tried to click the source button on the tv? It is the second button from the bottom on the right hand side of the screen.

I doubt your tv/monitor is turning off, it just isn't getting any input. D-Sub is the "pc monitor part".

Try clicking that button, give it sec, the hit it again. It will go through all of it inputs. If TV is what you are trying to find, it is directly after the Video input (green letters, top right hand side of the screen.) Keep hitting the button until TV shows up.

Good Luck!
