    Viewsonic N2750W Repair Strategy

    Picked up off the street. Noticed pry marks around the snaps. Currently, there isn't any reaction when I hit the power button.

    Also noticed someone decided to replace only the 1000uF capacitors with cheap replacements and used the 35V caps for all four. IIRC, there are two which only need 25V.

    This person didn't replace every C(r)apXon capacitor.

    I plan to do that. I did notice the capacitors have different specs compared to the list of replacements in popular repair kits. I remember seeing a 4.7uF capacitor and two 33uF capacitors.

    I vaguely remember seeing "Q11" but don't know if I need to replace that, too. I honesty am not familiar with the Q11 part.

    I see the two 33uF capacitors are also attached to a ... daughterboard? Backplane? Backplate? I'm not familiar with this board, either.

    I will test the individual transformers, too. What else should I test and examine?

    Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
    by lostone
    Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

    First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
    When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

    somebody familiar with hasboard repairs? BM1397AD interchangeable with Bm1397AG ? S17+ and T17+
    by stormanimal83
    i got myself a complete Antminer T17+ with 3 dead hasboards for a very good price.... for parts i bought S17PRO boards.... i replaced all missing resistors and changed some asics because they were bad... but wihout a tester... i used the miner instead and changed firmware to awesome miner firmware for better and faster diagnoses via miner log and lower fan speed...

    for my understanding and what i read on the internet these asics should be interchangeable in one chain but in my case i´m getting no more communication to none of the asics on all 3 boards. 2 of the boards weren´t in...

    by Returning Buick
    I have a G810 monitor i've had for years but it has developed a problem with vertical collapse. Is there anybody here who has worked on these and can help me find where the circuit even is for the vertical deflection?
