    Samsung LN40D630 horizontal line and "oscillating"

    i all

    I am new to TV repair and I need your help! at first, sorry for my english!

    I have a Samsung LN40D630 with an....oscillating? screen

    here's a video: https://www.youtube.com/watch?v=RVO962h2k_0

    I looked the caps, the bridge rectifier and I tested voltage at pin 1@5 on the t-con board and at fuse 1 for 13v and everything is fine. no loose cable.

    sooooo, bad logic board? bad t-conn board?

    thanks for your help!

          Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line
          by Ihandyrepair
          Hi guys

          I just started fixing 4k TV few months ago. so I am still learning a lot
          I got this tv from friend complaint is ghosting or horizontal lines on image.

          never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
          then it started to show the ghosting white image.
          I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
          it has 3 thin small boards at the bottom of the...

          Samsung UN50TU8000FXZC shows thin horizontal green line when warm
          by cubytus
          Hi to all,

          I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.

          I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.

          Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...

          Samsung LC32HG70QQUXEN - vertical and horizontal stripes across the screen
          by kotel studios
          Hi,

          Just now my Samsung LC32HG70QQUXEN monitor gave up on me. On cold boots I get many vertical stripes going across the screen (see the attached picture). After it runs for 1-2 minutes those go away but there are horizontal stripes going across the whole screen no matter of the input and PCs I use. (couldn't take an picture of it since the image size goes to 20MB and the camera doesn't pick them up)

          In a video about a 27" monitor with an similar issue the guy removes one resistor and supposedly the entire monitor goes back to life? For sure this fix is only temporary....

          Samsung eu58tu6928k - Short on CK3 line -
          by madyoyo
          Hello.
          I have a Samsung eu58tu6928k with the dreaded bootloop fault.
          No external tcon, one 96 pins ribbon between mainboard and the left side of the panel, and a ribbon to the right side.

          I narrowed the problem down to the CK03 line. When i isolate only this line on the ribbon joining the 2 halves of the panel, the tv boots, but the picture is quite bad. I also tested all MLCC caps on the panel, no short so far. Is there anything i can try before ruling the panel, and the whole tv as scrap?...
