Hi,

Appreciate the direct "Ask Me".

Often, problems such as this is indicative of a failing capacitor in the 5V internal regulator section. Most capacitors uses a wet dielectric that dries out after some time due to heat buildup. In some instances, most of the capacitors would also fail ESR test. Additionally, you may want to check the external power supply if it is putting out the correct voltage as indicated in the reverse of the adapter box.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

    Further analysis of your description reveals that it is possible likewise that:


    • the backlights are working hence the "...screen becomes fully white...";

    • which also is indicative that the monitor is not receiving or processing the video signal;

    • the electronics were messed up.
    This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

    Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

    Good luck and kind regards. Thank you for using FixYa.

Lcd becomes white


When a monitor becomes white, that means there is a problem with a capacitor or capacitors on the monitor's motherboard. These capacitors will be noted by their bulged top heads or they will be leaking. Capacitors work to hold down power from the source and keep it long enough for your display. And if any of these capacitors are bulged or leaking, they might not hold the power long enough or the screen will always be white. Find a technician who can open it up for you and carefully replace the capacitors

Acer crt monitor green light is ok but there is no display. but some time when i start computer it displays xp logo then goes away. i tried monitor with anoter pc but it still the same problem.


sounds like some of the components inside the monitor are becoming defective...the fact that you said some times you get a screen for a while then it goes away indicates a component is changing value when power is applied and shutting down the monitor...probably a capacitor in the power supply...best bet is to get a new monitor, as service rates would exceed the cost of a new or used one

Princeton 19" went from bright white to dull white


david78910, First disconnect and reconnect the monitors VGA plug from pc vga port a few times to make sure of good connection at the port. Report back here with results! If that doesn't fix your "pink screen" symptom, then possible bad inverter supply inside unit or the CCFL tubes may have lots and lots of "on" hours use on them and need to be replaced. Yes, you could also have bad (almost dead) switch-mode-power-supply inside unit if "known-good" monitor works perfectly with your pc. 12fixlouie

LCD monitor have Vertical lines and black colour become greenish


normally the 19" resolution can support up to 1280*1024, but if it comes with vertical lines in full screen, it might indicate the panel is no longer to work and probably it's time to replace new one.

Montor shows a blank white screen and is unresponsive


Please try to connect the monitor to another PC, if it continues to happen, then probably an internal electronic part/s of your monitor is cold soldered / defective which failed to send signal to other hardware parts of your monitor thus you only see white display. I suggest to bring the unit to an authorized service center fix / replace the cold soldered / defective part/s. regards

White screen on veiwsonic vg700b


Usually a completely white screen is an indication that there is no video signal being fed to the panel from the controller. For instance, if you take a working LCD monitor and just disconnect the video cable that goes to the LCD panel from the mainboard, it will turn on and off just fine, but it will light up bright white.

So, there seems to be an issue getting the video signal from your logic board to the panel. This can be caused by a bad cable, a loose connection, a bent and/or shorted pin (from plugging it in wrong), a bad logic controller chip, or a blown fuse/component on the LCD's circuit panel (PCB that runs across the top of the back of the LCD panel.)

Hope this help!
