    Celestron PentaView LCD Digital Microscope

    I have two of these microscopes, both take power and the lights for the specimen bed light up but there is not signs of life on the screen, I have checked the power button for the screen and the screen is getting power.
    I need help identifying some SMD components on the board

    For the first one has a model number of 44348 there is a three legged component (transistor/mosfet) with the marking N011V (Q4 AND Q5 in picture)
    The board has several numbers on it but they do not show any meaningful results on Google and I can't seem to find schematics for either of the boards (they are slightly different designs)
    The numbers on the 1st board are SQ917B_120215_VER1.1 and YZG0304XDGDM and 8EM4.3 1202001 and YZGB2B1203050b 00585

    For the second one has a model number of 44341 there is a five legged component with the marking SGA17 (U4 in picture)
    The board only has one number on it but it does not show any meaningful results on Google and I can't seem to find schematics for either of the boards (they are slightly different designs)
    The number on the 2nd board IS EM3.5L-MAIN-VER2-2013-01-15


    Thanks in advance for any help

      Need Digital Microscope Software (free)
      by Zentech
      I had a very simple software to view my digital microscope, the app name started with XP or PX then a number like PX5602 something like that. Anyway, I purchase another microscope and I installed the software that comes with it, and it uninstalled my previews app. I can't find it anywhere on my computer. I even looked in the registry to see if I can see its name and no luck. The new microscope software is bloated with buttons and I don't like the interface. Is there anyone who my have the link to the software? it has a white and very simple interface design.
      I have installed Xploview which...

      On the DM9 V3.0.1 it looks as if an HDMI port can be added.
      Question: has anyone added HDMI to this board? (I have not found Schematics for this board) So I don't even know if there are chips to support the HDMI output...

      Weak Vision due to Eye Strain when using Microscope
      by caspian
      Dear Forum Members,

      Microscope is required for micro-soldering and for measuring tiny components on a mainboard. I have to use microscope because my eyes are not that strong to see tiny IC pins.
      My microscope has light to improve vision. I have attached a photo of my microscope.

      Looking through a microscope gives us eye strain. After using microscope for 5 to 10 minues, my eyes get a bit weak in recognizing close objects. that means close objects look a bit blur. Then, I have to wait for 5 to 10 hours til my eyes get back to normal.

      1. Do you experience...
