Try separating your wiring. Touching wires can cause cross-talk of normal signals.

My monitor will turn on for less than a second, but then will go completely black. I've tried unplugging it and checking the connections, but nothing has worked.


mrtyler7, With monitor connected to a KNOWN GOOD pc that is displaying the WIN-desktop, then and only then turn-on the Viewsonic VX900. Note what happens. After LCD screen BLACKS out tell me if the desktop can still be seen if you point a bright flashlight 1 inch form screen??? You may or may not see the desktop depending on how far the "switch-mode-power-supply" has gone into SHUTDOWN mode to try and save it's self from a catastrophic faliure. Get back to me with result of test on fixya or by email. Also check out YOUTUBE for short video clips on "lcd monitor disassembly" or "lcd repair" or search web for stuff like "swollen caps" or "badcaps.net" or "bad electrolytic capacitors" !!! You may fall into this type of failure catagory. Let me know what plan of action you will be interested in. I will also let you know what other options you have. I'm louie12fix on fixya or lmistyrel@aol.com

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

After on for 5 minute tha screen go blank with blinking amber light


isa_cpu, Hi there, have you done the flashlight test after screen goes to BLACK? How old is E228WFP ?? Is it under warranty? Did it work "perfectly" the day before? Did you try it at another pc and get same result? If you shine a bright flashlight close to the screen after it goes BLACK, look very closely to see if Win-Desktop is still being displayed on lcd screen. In any case, if you don't own a DMM and soldering iron you still have these options! Call DELL and see if they have a swapout program. You send your's+$40-$90 and they send you a REFURBISHED same model in return with new cold-cathode-fluorescent-tubes w/inverter&smps installed. or Check for local TV/Monitor guy that knows forward&backwards all there is to know about fixing lcd monitors. It may also be informative to search web for Bad Capacitors in LCD Monitors or Repair of LCD monitors and also check YOUTUBE for short vids on LCD repair or disassembly. I'm louie12fix on fixya or lmistyrel@ aol.com Bye for now.

Monitor went black in seconds


oboy, One thing to try is the flashlight test. and get backto me with your findings. Tell me, does this lcd show a nice display only for 1-2 seconds and then a black screen when connected to a fully booted PC with Windows desktop displayed? Shine a bright flashlight 1-2 inches from panel and tell me if you see the WINDOWS START Button at lower left of screen even though screen is black! Get back to me if you can. I'm louie12fix on fixya or lmistyrel @ aol.com BYE for now.

Gateway Monitor keeps going black


Alicia, Your monitor digital board is OK. The problem is with the power supply/ Inverter board(s) in back of the LCD/LPD Panel that you look at. You will need to question Gateway to see if they have a swapout program where you send them $30-$60 and your old monitor, and they will send you a refurbished (new cold cathode fluorescent tubes w/inverter board installed ) complete monitor. I'll tell you one thing though. Alicia, Don't feel bad abt this monitor of your's failing. You have joined the club with over 2000 others whose CCF tubes and INVERTER boards have with time now fail to light-up their LCD panels. Yes, there are some companys that do repair of these monitors. Try surfing under CCF tubes or FPD repair, or LCD repair. Yes Alicia, you are dealing with a technology similar to the new type of screw-in light bulbs, only the tubes are thinner and laid flat horizontally across the rear of your LCD panel with a reflecting mirror in back of them. Good luck girl in getting it repaired. I'm louie12fix on fixya or lmistyrel @aol .com North of Chicago 40 miles

Try unplugging the power cord to your computer tower, click the power button to drain the capacitors in the mother board then plug the power cord back in and try to boot up. Has helped me repair several similar black screen problems. Chuck Housecall101@aol.com

Green light on - screen on briefly, then goes black.


Replacement is probably the only option at this point. It would cost more to fix than it would be worth new. Try going to: www.tigerdirect.com www.newegg.com They are usually running cheap specials on monitors.
