My phillips brilliance 151ax lcd monitor shows blank light screen when it is first turned on. After about 4 or five minutes the monitor works fine, and continue to work fine until it is turn off and stays for for an hour or so. What's the problem?

In my monitor ( Philips 150 S) , the message come very frequently as " OSD main controls locked", what is the solution

Unplug monitor form AC outlet, wait for few minutes and plug again.
Check cable attache to PC.
Hope this trick will work.

press OK button for more than 10 seconds

1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.

2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.

3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.

Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.

ViewSonic LCD (VA1912w) Went Blank

I am using this great LCD for about an year. But few times in the past my LCD didnt show up the display though the Green light was still ON, turning off the LCD and opening it again always solved the problem. But now My LCD completely went blank. Turning off/on didnt work at all now. I've tried couple of other tweaks mentioned on this site but they didnt work. I am just seeing a blank screen with green light ON. and ya theres a very low hissing sound coming from the LCD.

Beautiful screen, lasts about for a few minutes, goes black. Power button still green. If I turn it off, and then back on, it works again for a while. Any ideas?

Throw it out the window. Acer sucks.

ccfl ( cold cathode flouroscent lamp ) is the backlit feature of the lcd panel. If you see a blank screen but do see the output on the external monitor then you sure have to take it to the hardware tech to get the inbuilt LCD panel checked. it seems to be a electronic failure. Thanks Ashish.

There is probably a bad capacitor within the monitor that will not allow the picture to "hold" in the on configuration. This will need to be replaced. You can send it back to Phillips, or 17" monitors are pretty cheap these days. I would suggest a Samsung or BenQ. They both carry 3yr warranties.

hi if your sure that all the power settings of the screen and the comp are fine then it points to 1 reason: the screen is heating up and the automatic circuit shuts it down... try locating it some cooler place or put a vent behind it... see if it does any help if soo set it in a cool place good luck
