Having problems with your CTX Computer Monitors ?

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


Answers :

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 [email protected]
