SOURCE: Screen powers up then goes blank after 2 seconds

Hi, was there a resolution to this? I am experiencing the same problem with LCT3285TA purchased at Radio Shack in Media, PA. Radio Shack has refused to service the unit and has put me over to Akai for the manufacturer's warranty. I'd like to know what to expect and if this problem with the Logo coming up and the unit shutting off/restarting can be easily fixed, thanks.

SOURCE: NEC 19'' LCD monitor power on but screen blank

If you can try it on another unit , If it still does not work, Then the most likely culprit is a bad power supply. If you know any thing about soldering replace the capacitors they are probably bad but being that these things are being built so cheap.It could also have a bad inverter. not repairable by average dude.If you open it be careful and do not attempt unless you feel comfortable with a solder Iron.Hope this can help you Good Luck. www.IrionsTVshop.com board re builders.

Try turning the tv off, then unplug the tv from the wall for at least 60secs. Plug it back in. Turn it on and see if the blinking has been reset to normal.

This does not seem to be a power supply issue but rather an issue with the backlight inverter board. When the screen goes black, take a flash light and focus it on the screen from a close distance and several angles. See if you notice a very faint image. Try changing the channels to make it more noticeable. Try it and let me know

Screen goes blank after 2 seconds


Do you have the video set to a range that this display cannot handle? Try rebooting into Safe Mode and set the resolution down to 800x600 or 1024x768 and see if it that will get you back. If so, then look up the specs of the display and set it no higher than it's max.

If it physicaly powers OFF, then you probably have a power issue.

Swicthed on tv and its a blank screen..now it wont switch off.


Can you see the menus on the screen?
Can you hear audio (sound)?
If you can hear sound but no menu we need to check the backlight.
Take a flashlight and shine it on the screen, look very closely at the screen.
Do you see a video image?

Let me know what happens, I can assist further.
