Samsung syncmaster 931a... connected to computer

\015 Samsung syncmaster 931a... connected to computer and computer running, when monitor turned on, blue light stays on and display appears (with desktop properly displayed) for approx one second, then goes blank, blue light stays on. turn off and repeat, the same happens. this was recently acquired, and I'm using a 14 pin analog cable.. does it need a 15 pin cable? With monitor disconnected from computer, the same happens, only the small box ''analog or digital'' appears in upper left corner for the brief moment. then the backlight goes out.\015

Answers :

Hi,\015\012its unlikely to be the cable. Most likely cause of this is a faulty inverter board. If you are lucky it will only be 1 or 2 blown capacitors which are easily identifiable and replaceable once you have got inside it. it could however, be almost any of the components on the inverter board or even a failed backlight but this will require further testing and a knowledge of LCD monitor workings.
