Haier 50e3500 doesn't have backlight. Can't change brightness from 0

Anyone know if this is why it's so dim, or if by default, it won't allow you to change from 0 if the led drivers are bad? Installed new power supply thinking it was the problem. Don't have a remote, and not sure how to change led backlight brightness

SOURCE: Intel D865PERLL Motherboard will not power up

Hi nkda2000, this is as close as I could find for power schematics. Intel D865PERL
http://support.intel.com/support/motherboards/desktop/D865PERL/sb/CS-027143.htm

(There is no Intel D865PERLL board). Sure it's a typo. Have done searches for D865PERLL & found it (Not on Intle's web site) but when looking at the specs it's listed as D865PERL. (One L ) not two.

I hope the Technical Product Specification pdf can help you check the power on the motherboard.

Luck!

Mike

SOURCE: hp laptop 9720us screen wont brighten or dim. last

You got the wrong inverter fitted - i'm sure your unit requires a sinle lamp inverter and they have cheated - putting in a generic lamp inverter and branching togeather the wires to accomodate the single plug thus reducing the available volatage for the lamps - this is why it's dim - correct part is 431391-001 Display panel power inverter - For use with single lamp display panel

How do you turn on the Backlight on the screen?


If the screen backlight is not on, first try adjusting the brightness.
Press TV/AV button on remote to select TV mode. Press the MENU button on the remote. Using the arrow keys (navigation buttons), choose picture mode and adjust the brightness and contrast.
If your TV screen is still not lighting up in a dim room, then the backlight is broken.
You have 90 days labor and 1 year parts from date of purchase.

Dark Screen even when i adjust the 'brightness' tab?


check the power settings on te unit, if it is set to default for the backlight, possible that your LCD's backlight is not powering up properly on the unit or LCD's backlight needs replacement.

My laptop, hp compaq nx6110 has a screen problem. Its dim


OS?

Check the "Power Options" in your "Control Panel" (classic view). For whatever option you have picked, click "Change plan settings". There you can either "Restore default settings", or manually "Change advanced settings". If you choose "advanced settings", look for "Display" / "Display brightness".

Background lighting gone crazy


Ok, this problem is a game glitch, if you downloaded it from the internet, it may have some bugs or some glitches that screws up your phone. I suggest you go back to the shop and exchange a new phone because if it was only three days, the warranty is still valid. So go to the shop immediately.

Backlight not working


Did you try to set the Backlight on in the control panel? (settings>system>brightness) The brightness is often automatically set to 0. If you did this already and it still doesn't work, probably try an email.
