I have been having the problem of picture cu-out recently - the screen starts up ok, but picture appears to cut out after 10 seconds. I can see the picture if I shine a torch on the screen so it appears to be the back lights. I thibk its something to do with their power supply maybe. If Ipress the auto tune button the back light comes on for a few seconds again then backlight goes out. please advise what could be the problem component to change. I guess this problem is not the CC tubes as I have a second identical screen and if I swap the power supply I get same on the other screen os its the power supply I assume. There are mainly passive components caps 1 or 2 electrolytics and one main chip BA9741F and 2 smaller ones BE4U14 - msny thanks

These were a fine monitor and with the kind of image quality you cannot get on TFT's. If you know the graphics card you are using is working ok, have checked the VGA cable connection and socket at the monitor and computer and have tested the monitor on another computer, that would rule out any problems as far as connected devices are concerned.
The problem you describe, and it is unusual that it has happened so quickly, points to a failure of the monitor internal board. You may be able to get this repaired at a reasonable cost by seeking the opinion of a TV repairman, who might be able to fix it.
From time to time, I've the same white screen problem with my IIYAMA E1902WSV.
I can resolve that issue with a reset to factory settings. 1- Turn ON power (blue led) 2- Push on the MENU button and keep the button pushed while pulling out the power cord. 3- Plug the power cord back while keeping the MENU button pushed.
1) Boot your PC 2) when the grub menu appears, use the down arrow to get to the menu option listed as (rescue system) 3) when the text-based menu appears, choose a menu option that gets you to the root shell, then following the instructions mentioned in this link: http://www.cyberciti.biz/tips/black-screen-while-starting-x-window.html. Debian instructions will work for Ubuntu.
It does indeed sounds like the capacitors, I had this problem last year with a Medion monitor where it would turn on and off, when I spoke to Medion they did say that it would need a repair but at the time I wasn't enclined to pay the repair fees for something that may happen again!
Personally I would stick with your plan of getting a new monitor because my view on monitor hardware issues is that if it's happened once it will happen again even if you do repair it resulting in a lot of hassle!
One of the buttons on the front of your monitor is probably stuck. (Only one of the buttons work at a time on most monitors)
I cannot recommend taking it apart your self (have a tech do it) But take off the front, check the buttons after you take off the front, and if it still occurs unplug the buttons from the monitor. If it stops (which it should) replace or fix the controls) If it doesn't, call an exorcist (just joking) or buy a new monitor.
Check that the power cord is fully plugged in first.
It is probably the inverter board inside the monitor. (if the screen does properly display ever then it is not the screen) It CAN be fixed but I do not suggest anyone open up a monitor (LCD or CRT) who is not "technically inclined."
If you really want to fix this particular one then take it to a local tech and get an estimate first. If it's almost as much as a new monitor then buy a new one.
