Having problems with your CTX S760 (Beige) 17 in. Flat Panel LCD Monitor ?

Hello, A family member gave me a CTX S760 17- LCD Monitor. When I hook it up and start my PC the screen looks GREAT for about 15 sec or so and then goes black. Same thing will happen if I power off the monitor with the PC on and then power up the monitor, after 15 sec or so it will go black. Any info would be helpfull. Thank you Chris

Christoph972, This really sounds like a SMPS going into SHUTDOWN MODE after detecting a fault in the "cold-cathode-fluorescent-lamp" electronic ballast circuit which is called an INVERTER CIRCUIT, or it has a problem all by itself. The big question is? ? ? WHAT is causing the fault? I need you to do the flashlight test to evaluate the condition of the LCD monitor's "switch-mode-power-supply". With a KNOWN-GOOD, fully booted pc that has the WIN-desktop showing, reconnect the S760 to the pc. then and only then push the "ON" button for the monitor and note what happens. After the screen goes black, shine a bright flashlight at different angles about 1" from the LCD screen. Get back to me with the results of test. Did you see or not see the WIN-DESKTOP? Also visit YOUTUBE and search for and view videos of typical lcd monitor disassembly and or lcd repair. FYI only!! The longer ones (8-12min) will be more informative. The symptom you have with this freebie monitor is classic! It could possibily be repaired for $12 or less. Get back to me here at fixya by posting another comment to the above stuff you already did.
