Answers :

Carrizosas, Tell me more. How old? Approx. total "ON" hours of use? Did it display a "bright, crisp, full color text and graphics and pictures the day before? Does this unit have a lay on floor "BLACK BRICK" ac to dc supply, or only a 3 wire line cord to the wall outlet? Have you swapped-in an old KNOWN-GOOD monitor to prove that the PC is not the bad guy? When you push the "power ON button, will the screen flash "ON" for 1 or 2 seconds and then go to a black screen when connected to an already fully booted PC with the WIN-desktop being displayed? By the way, have you performed the test that every owner of an LCD monitor should know how to do and be able to interpret the results of the test into useful troubleshooting information? Whenever faced with the dreaded lcd BLACK SCREEN symptom. Do the FLASHLIGHT TEST(torch test if Atlantic ocean is west of you) to evaluate the current state (condition) of the LCD's "switch-mode-power-supply". Here is the test. Reconnect the BLACK screen lcd monitor to the previously mentioned KNOWN-GOOD, fully booted, PC with the WIN-desktop screen displayed. Then and only then Press the "ON" button (on/off front panel switch) for the LCD monitor. Make note of what you see or don't see. Did the lcd screen flash the desktop screen? If it did, for how long, before it went BLACK. Next thing to do is hold a bright flashlight (torch) 1" to 2" from front of lcd panel and look very closely to try and see if the WIN-desktop is being displayed on what looks to be a BLACK SCREEN. Now we will interpret the SEE or NO SEE results. If the desktop was visible during TURN ON and did not see the desktop with the flashlight, it means that the SMPS has detected a fault with itself or the inverter circuit and gone into TOTAL SHUTDOWN mode to save itself from self destruction and or becoming a fire hazard. For those of you did or did not see a 1-2 or even 5 second flash of the desktop screen at the TURN-ON point, but with the aid of the flashlight you CAN see the faint image of the desktop being displayed, this means that the SMPS is still partly alive and is supplying voltage and current to the lcd digital signal processor interface board and is in a PARTIAL SHUTDOWN mode having detected a fault with only one DC output source. Most likely the one that powers up the "cold-cathode-fluorescent-lamp" electronic BALLAST circuit which is commonly refered to as the INVERTER circuit and changes a dc voltage (12-15v) into ac voltage (800-1200v) to make RAW WHITE LIGHT so you can see all the pretty colors displayed on the LCD panel. Now that you know some of the basic operating principals of LCD displays you can get back to me with answers for the questions asked by me at the start of this fixya response. I hope the information will be helpful to all that read it. I'm louie12fix on fixya or [email protected] Bye for now.
