Re: No display, clipping sound appear
The clipping sound is the internal safety switch that keep shutting down the monitor. It means there is an internal problem on the main board (overvoltage, bad component , short). Try unplugging power cord and leaving it unplugged two or three hours, this will reset ICs by draining power completely from circuits, it is called hard reset, it rarely works. CRT monitors waste up to 15 times more energy than TFT screen, if your CRT starts giving troubles, then it is a good time for upgrading it to a new TFT. 17'' start at $120

Causes of OSD LOCK
1. The monitor is incompartible with the system unit, especially for newer version units versus older monitors
2.Older monitors display attempting to much up to the improved definition functions of newer system units display an operating system malfunction, interpreted as monitor malfunction instead. OPERATING SYSTEM DISPLAY MALFUNCTION
1. consider changing the graphic card on the system unit after attempting to adjust the appearance settings on the desktop once the computer is powered on.
2.Once changing the graphics card on an old system unit, consider changing the processing chip for reasons of achieving peak performance of the new part installed.
3. Once the fxing of the parts are complete, the monitor would continue to display OSD requiring entire system restart or book. after which, adjusting the appearance setting that should by which time display new list capacities due to the new device changes
off mode in 5 sec,problem represents that the data cable is not properly connected or the monitor is unable to recognize the connection once check your key board lights above the num pad when you switch on the PC if the lights appear . Then the power supply is not provided to only the monitor unplug the data cable and plug it again properly,even if doesnt solve your problem just shake the data cable receiver pin located to the back of the monitor.
If the lights on the keyboard does not appear the problem is within the cabinet it may occur due to the dust too,so clean it properly , using a hair drier for blowing the dust is better.
It's time to responsibly recycle your old CRT monitor, and spend about $100 to buy a new 17" or 19" LCD screen, rather than spending any money at a qualified TV/video technician, trying to trouble-shoot the problem.
The specs for this monitor is a 60 Watt, 12 Volt, 5 Amp power adapter. The voltage must be the same. You can always get an adapter with a higher Amperage rating, but never get one with less, as this can overheat the adapter and damage it. I was not able to locate specs on whether the voltage to the monitor is DC or AC... most are DC. If this is the case, the observe the polarity at the monitor. Power adapters have a positive and a negative... center and outer contact, Make sure that the power adapter matches that of the monitor, else it will not work.
15sunnybank, Did you try swapping it to a different PC to make sure that the problem is in the monitor and NOT in your PC? Sometimes when the DC voltages (which power up the electronic circuits in these LCD displays) become marginal due to age of unit, then weird stuff like unexpected/uncalled images/menu's could appear. First have a TECH type friend verify if all dc voltages are within specification. One more thing!! Don't post here without letting us know some history on the unit you hope to get help with. Age of unit?? Approx total # of "on" hours??
What happens if you put a 10 inch fan blowing cool air into the monitor?
