    I have 4 monitors all the same age (Oct06) which have all failed within 2 months of each other. If it is unplugged for a day or two it will fire up again. These monitors run 24 hours a day. When replaced with other monitors it is no problems.

    Hi, I've got a ProView flat screen that became like that after a power surge.

    Basically, it turned on when I pushed the On button. Yellow LED switched to green. Then, after 2 or 3 seconds it went blank.



    So, suspected from the backlight inverter board: a Sampo QPWBGL8981DG PCB. Replaced the two 330pF / 3kV capacitors after the small transformers.

    I then thought I had repaired it for good.

    After switch ON, I can now get an image for 1 or 2 minutes. But then it goes blank (no image) again. LED keeps green. If I switch it OFF and ON again, image comes back on for a shorter time, say 5 seconds, and OFF it goes again. If I keep doing this Off and On switching, it keeps showing an image for 3 seconds each of the times. But I can't seem to keep the image on forever!

    Does anyone know what else could be damaged (besides the capacitors) on that Sampo Backlight inverter board?

    Regards,

    Njso

    My 17 inch Dell monitor powers up with no image. It flickers , but will not hold the image.

    We have suffered power outages and brown outs this winter. Is this repairable?
    It is not the video card as we have hooked up an old monitor.

    I've had my monitor for a couple of years, and today, after I turned on the PC< the screen went blank. Recycling power, the display would return, but only for a second before going blank again. Problem remained after several iterations of this.

Your symptom is commonly caused by failure if the inverter circuit. It is made by Sampo. The inverter powers the backlights. Replacing the inverter is the first step to resolve the problem.

If there is green light on monitor.so you just check the vga card and ram.First check both are placed in the slot correctly or not.if it is so then replace new one by one .then you can catch what is the problem.and can fix by urself.

As one of my "initial things to do," I unplugged the monitor and then replugged it in and it did not fix anything.  Then after reading others' solutions, I unplugged the monitor and let it sit for about 15 minutes. Once I plugged it back in, it worked just fine. My setup is a laptop with docking station - the monitor in question is attached to the docking station as a dual-screen setup.  Though this may not matter technically, it might help those searching for solutions. Thx! Jake

Without much information given as to the state of the monitor - Check the LED on front. If Orange, it's getting power and the has a problem. It could be: Fuse Digital Board Power Supply If Green Check the Video Card on PC If None/Off (with unit unplugged) Sniff & Check the power supply board of the display. for Fuse and Visible damage.

Try, if you can another monitor, if same problem, check graphics card connections(connection to your monitor) and if you are able re seat graphics card. If you have frequent power failures, you probably have power surges, this can be a problem as they can fry various components on the motherboard, check that you are getting 2 beeps from your pc when starting it up, if there isn't, your pc is not booting up and your monitor will probably display an orange light (stand by) instead of green.

I eventually contacted Samsung support and basically it is a component failure so a new unit was supplied under warranty. Unfortunately there was no software fix they had available.

Hi Rey,

Hope this helps you like what I did to resolve this kinda problem. If you can manage to open the chassis/cover check first if the HOT (horizontal output transistor) is good, if good check the SMPS (switching mode power supply) primary and secondary side if there are short filter capacitors, diodes, transistors and open resistors. Major faults to consider is by checking the load of SMPS, control circuit, driver circuit, feedback ckt.

Please let somebody to assist you (a certified technician) how to open the chassis safely due to electric shock. Please be guided accordingly.

Best regards,

Try to plug into another computer and wait to see.
If it turn up to be same it somewhere defect from the main board of the lcd.
If if not the same turn up to be, you should reinstall the OS because the software is corrupted or your display card problem.

Will not power up. Is there an internal fuse?

Hi,

Try to diagnose the problem .
Replace the monitor and see if u get the signal...if u get display with another monitor then motherboard is ok.

are you seeing a picture before it goes off?
make sure the DVI or VGA cable is securely fitted into the monitor and the computer
go to the menu and check that its power saving timer isn't set too low.

Probably not, unplug the monitor for about 5 minutes, this may reset it. You may also want to unplug the power strip to see if that resets.

Monitor keeps blank even the power lLED is on green

If it's working fine in DOS, it can only be your display drivers for your operating system. What happes when you start in SAFE MODE? When you PC starts, keep pressing the F8 key, go to Safe Mode. If it works, bring the Resolution down to 800 X 600 and load the new display card drivers. Restart, should be fine.
