    all these have been checked NO results.

    many thanks john chapman

    further to my previous comment, if you have any more ideas I will try them.

    However it seems a burial is called for. A point of interest :- it is two months over its guarantee.

    Regards john chapman

Hi,

There could be few possibilities.Unfortunately, as i am not there, i could only provide few details that would help you to diagnose the problem and take an appropriate action to resolve it :-

1.If there was something wrong with the graphic card, you would see atleast some Junk data (garbled image or something) on your monitor.
2. When the monitors goes off, the light would had gone "off" or changed color (if there is a sleep mode light). But it stays white and this shows that the monitor's main board has issues. (issue can be anything like some IC getting heated up or a loose connection)

Solution:
1. Make sure that the power and data cord of your monitor is fixed tight. (behind desktop and behind monitor). My guess is you have already done this.
2. Use this monitor with some other computer and see if it works fine. If it does, than there is something wrong with the graphic card or its compatibility with your monitor. If it doesnt, than get it replaced.


Mostly this happens because of a bad Data or Power cable of monitor. So replace both the cables of Acer monitor and see if it works.

If it still doesn't work than its 100% a hardware problem on the circuit board and unless its in warranty, the repair will not be worth it.


Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    Unfortunately, there is no magic wand that could resolve this. If you have check the cable, the most probable cause is hardware failure. If you have electronics repair experience, could use multimeter and soldering iron, i would be more than happy to help you to even repair the set. However, there is no RESET button on any of these monitors ( though i wish it could have )......

    Thanks and Regards

    Mr Chapman, as the warranty expired only 2 months ago, it would be a wise option to give a call to Acer and see, if they are willing to help you. Sony does this very often and that's what is meant by Customer Service.You might have to raise the voice and might speak with a supervisor or manager and more likely they might repair the monitor either free of cost ( which i doubt ) or charge you only for parts ( most probable ). I cannot guarantee the success, as i do not represent Acer. However, if you start the conversation with their customer relations that you need to get it replaced without any cost, and then follow up that you would love to pay for parts, however there should not be a labor charge, would be the best option. The parts cost would not be as high as the service call cost.However, this happened with few of my clients with Sony and Hp and they the manufacturers accepted the complaint gracefully.

    Thanks and Regards

Possible that the power shunting is due to weakness in the circuit and so the processor gets a faulty feedback.
The circuit in the main board must be checked with a multimeter or if you are equipped with a scope to trace the feedback loop back to the processor.
Weakness of capacitors in the power will not build up voltage and so when the circuit powers up there will be shortage of the +B which will result in tripping the power and continuing. this is one possibility.
The other cane be due to higher drain current in the drivers and power sections inthe main board.
Observe for capacitors that have leaked or bulged at the top. If so replace and check.
Finally check for dry soldering or poor joints in critical circuits that will prevent correct voltage and current to build up resulting in tripping.
use a good iron to touch up all suspected points.

    Too early for a set to fail but the intermitent faults like you mentioned need a lot of probing before we can pinpoint and hence I would request that you must spread the board with a good light and start checking the deficient voltages to get to the fault.

Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Try to reset your camera using a command in the set up menu. An error message followed by turning itself off, usually means lens jam. Replace the lens.
