What stand do you have? If it is screwed to the back with 4 or 3 screws, they must be removed first. look along the bottom edge and you will see 3 slots where the two outer cases match up. Put a flat screwdriver into the opening and twist, follow all the way around until you can remove the back half. Cut the tape holding the flat wire and remove the front half to remove the printed board under the front cover. You should now be inside the case. Remove the screws to remove the steal cover to find the printed boards under it. Reinstall is the reverse.

I have a similar problem with my screen, same one, 15". For a period of two years it would turn black for an instant and resume functioning. Since two weeks it only flashes the picture for an instant and then turns black again. We opened it up to check the wiring but nothing wrong there. We are 99.99% sure that the problem is in the screen itself and has nothing to do with drivers or anything else in the computer.
If you bought it less than 3 years ago and since it is probably a result of faulty construction, it should fall under warranty (by european law).
I am going to take mine to a repairman tomorrow, i will inform you wether the screen can be repaired or not.

Greetings,

ok try this one switch the hard-drive off and on again to restart it and then the screen would come one.

Check the all the cables. Check input settings by using the menu.

• Larry Ng Jul 15, 2021that is just a YEAR 2007 LCD computer monitor, it needs a computer to work. if it fails in a 2nd PC , if that test fails,the monitor is bad. (hardward failure, monitor. the tests are simple, it fails on 2nd good PC, what can be more simple that test ANY 14 year old monitor on a 2nd good PC. when dead do this.(test2) they are all here when dead again use a FLASH LIGHT. (or in UK a low carbon foot print TORCH)<< joking. https://pcdied.com/monitors_and_screens/... all monitors older than 2010 do this . (has CCFL inside and that is never fun now) the cure is newer monitors 2011 to now called LED monitor.s or OLED. the tubes are cold cathode florescent tubes. (back lamps.) (have 5 classic fail symptoms not just dead) they are short lived, laptops and monitors both back then. 20,00hours on the clock and go bad. bank on it. the 3 failures are CCFL, PSU board, and logic board #1 is CCFL the all died long ago, on average about year 2003 (07 +5= 12, 2012) at 20,000 yours boom dead. or intermittent. PSU is here: https://pcdied.com/monitors_and_screens/... below is logic board. one of the 3 fail, CCFL tubes dead is like 99% we retire them if the CCFL test fails. (using bench PSU to test them) but you have non of that so. upgrade
• Larry Ng Jul 19, 2021 logic board. (CCFL tubes dead, PSU dead, or logic board dead) and or thermally failing , and bad.
• Anonymous Jul 23, 2021 99% of all monitors are all dead. due to those silly low live CCFL back lamps. or the 2cards inside that can fail too. PSU card +HV CCLF power or the Data card is dead. 99.9% of folks seen these facts, upgrade now. high voltage inside 600v on the CCFL pins

Hi, Sounds like an issue of the video card not the monitor. Take to computer shop to verify. One thing you can try is drop the dpi down (refresh rate)a bit. Then try again. If that makes sense to you. Hope that helps.

Hello, It´s not safe to anchor it to the plastic back, monitors usually have a metal frame inside that support the weight of the monitor.

Flatron l17175 what on earth is that? ahhhhhh and LG, lucky Goldstart monitors. not HP. wrong forum Ill move you.

You need to use a ESR meter to check capacitors

If you get half of the screen darker, remember that LCd monitor have 2 neon lamp at each extremity of the LCD, when one goes out you get this problem. it is possible to replace the LCD neon lamp, I did it many time, but you need to tear all the monitor appart and be carefull not to break any glass while doing so.

Normally your computer display goes to sleep mode when the attached cpu is not turned on..

are you in dual screen mode on a laptop possibly? Check that the laptop is dual enabled so that it is either an extension or a duplication of your main screen. This is common mistake in setting up external monitor on laptop.

you need to look at the geometry settings on the video driver on your computer to find the right set for your monitor. There is some adjustment in your monitor to choose 4:3 or 16:9, but in PC mode this is usually over-riden though.
