Question about Sharp LC-M3700P 37 in. HDTV-Ready LCD Television

1 Answer

Monitor comes on for a few seconds then goes blank.

I have a Sharp LC-M3700 Monitor/TV When you turn on the set, in this case its attached to the computer, the screen comes on but only lasts for a couple of seconds then goes blank. The power light in the lower right corner that was green turns to a flashing red light. If you shut it down and start again I get the same results. I appreciate any help you can offer. Tony

Without more information, it sounds like someone might have set the parent protection code. Was your TV a demo unit maybe? You should be able to reset to factory default settings, but you'll need the manual for the TV for this. If you have more details on when and where you see this message, please elaborate.

Try to do this: Just before the Windows start up screen (after the bios loading) press F8 and log in at safe mode settings. If at this mode you can see your screen change the resolution settings at a lower set. Save and reboot normally. Now try step by step to increase your resolution. In case of a blank screen appears at a new setting, don't do anything; after some seconds the monitor will come back to the previous settings. Save and go on.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

Hi ,
The monitor flicker problem. The monitor when turn on will display image for couple of second then turn black. The monitor status led is still green. This will happen each time it is turn on. The symptom at appear to come from the inverter board.

Show Microsoft Power point on Sharp Aquos hdtv


try to right click the desktop and choose graphics options, you will have to select the correct output for your setup. i.e. laptop to monitor, etc etc see if that works,...sounds like you have a connection, you will have to play with these settings until it pops up. worked with a similar scenario, sometimes you have to do stufff twice and it works on the second time not the first, electronics are weird.
keep changing the settings in the graphics options until it comes up the way you want it.

Comment by Guest, posted on Oct 25, 2008My Aquos has the same problem. I'm not sure how I discovered this, but when I lean the TV forward and hit the power button it will turn on every time. If the screen blacks out and I don't lean it forward when I hit the power button, the screen will just remain blank. It is very weird, but at least repeatable.

- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.
