Hi,

If you are referring to a conventional CRT monitor, then the fault you have described is indicative of a cold solder in the vertical section. Often, this would be any of the pins of the vertical IC. The vertical IC is the only IC that is heatsinked and sits at the back of the flyback transformer.

This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

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...


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.

Hi we have a ctx monitor PV720A that stays on for a couple of seconds then goes black


glenn659, possible cause is bad internal switch-mode-power-supply" failure or SMPS is detecting something wrong with lcd cold-cathode-fluorescent-tube backlighting circuit, (INVERTER) and it goes into SHUTDOWN mode to try and prevent a catastrophic failure from occuring. Glenn, visit youtube, search for video clips on LCD monitor disassembly and also also research BAD Capacitors or Swollen Capacitors and also the "WHY DO LCD MONITORS FAIL PREMATURELY" Certainly your's will be in the top two causes! Did you do the flashlight test with your monitor "on" and connected to a known good PC with the WIN-desktop screen showing. Even though screen is BLACK it might still show the desktop when you hold the light about 1" from screen. Some will, some won't depends on condition of the power supply. In any case get back to me with your plan of action you intend to take after viewing YOUTUBE stuff. Bye for now. I'm louie12fix on fixya or lmistyrel@aol.com

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

17" Monitor keeps going black


Hi Rahni, It's a very common problem. LCD's use four small Cold Compact Fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino
