    Anyone seen this LCD MONITOR problem before?

    here is my problem

    www.youtube.com/watch?v=QzT58tOmf-*8

    I have taken the monitor apart to just boards and looked for faulty components or bad solder joints by sight. I see no burnt or damaged parts or caps after thorough investigation. Would like to find a fix for this for under 80 bucks because the same monitor or even higher models of the monitor are selling on craiglist for $75-$100. Is there any thing you can see from these symptoms? It flashes on twice. First is BenQ logo screen then second is no input detected screen then stays blank. Anyone come across these symptoms? or anything similar and has fixed them? Check my other post for pictures

      Problem with monitor DS-D5022QE-B
      by Askic
      Hello to all,

      I have a problem with monitor that is delivered together with CCTV system.
      The monitor appears to be completely dead, there is no LED power diode and it doesn't react to pressed power button.

      I have disconnect display and check many components on the power supply part of the board. There is no anything obvious and monitor is about 3 years old. There are no bulged caps. When measuring voltages on the output connector to VGA board I can measure stable 14.5 V on 12V pins and stable 5.07V on 5V pins. So I assumed that this part of the board is OK....

      Samsung LU32J590UQUXEN Monitor display problem
      by CptChronic
      I have an intermittent display problem with my monitor, when I plug in the HDMI cable to my (or any) laptop, you see the connection screen shrink on the laptop as it usually would before displaying on the monitor but 95% of the time the monitor display stays black.

      Before it cut out all together, tapping the monitor control button a fair few times would make the screen display, and everything work fine.

      But now it never does it. Not sure what's going on, hoping someone can help. I'm capable of stripping the thing down and soldering in new parts if needed, or programming...

      LG 24MP56HQ-P Monitor Backlight problem?
      by tmhobadcap
      I have a few successful experience in fixing tv backlight problem. But for monitor, I have no experience. However, I think they are more or less the same. Am I correct?

      Recently, I got the captioned monitor and the owner said it could not be turned on. I open it up and found that one of the SMT capacitors seemed to be bad. I replaced it as well as the other one. The monitor still could not be turned on.

      I found the power indicator is on. When I shine a flashlight on the screen, I can see the image. Therefore, I think it is with backlight problem. I took out the led strip....

      Pioneer PRO-FHD1 Elite Plasma Monitor Start-Up Problem
      by Phil Stasik
      Pioneer Pro-FHD1 Elite. Failure to power on.

      I'm new to this awesome forum, and have been reading like mad, but have not seen the answer to my challenge.

      We bought this Panasonic plasma monitor 16 years ago and it has never been serviced, so all parts are original, and the unit has never malfunctioned -- until about a month ago. The system fails to power on. At first (a month ago) this happened rarely. We learned to unplug for a few minutes to drain the caps, then re-plug, and the monitor would start normally. Now, we plug-in, turn on the main power switch, and the...
