    Impression 7LSP Monitor

    I have an Impression 7LSP that I donated to the school. One day, it died. I pulled it apart and saw that the capacitors had leaked in the power supply board. After watching a few on-line videos of fixing these, I dove right in and soldered in new caps on the power supply board. I plugged in the power and a computer, and the monitor came to life, the speakers work, and all is well?

    Almost. The video shows five ghosts to the right of all words or vertical lines. No problem you say. It must be bad caps on the video board so I solder in all new caps on the video board. Now the colors are superb, the video is bright and clean, but the ghosts are still there. The second issue is when setting the resolution to 1280 pics, the video is off center and can't be pull from the right to the center. At 1152 pics I can center it.

    Has anyone had similar issues that they have repaired?

    I don't have a schematic. and don't know which circuits I should be looking at. I am guessing it must be on the video board. Any suggestions?

    LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
    by Hakuu
    Hi There,

    This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

    After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

    HannStar Hanns-G HC194d LCD monitor repair
    by momaka
    Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

    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...

    TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
    by howardc64
    All left and right refers to looking from rear of TV (or looking from front with TV upside down)
    • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
    • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
