    Sony KV25fs150 with diagonal lines.

    I am repairing a Sony kv25fs150 and when this television is switched on there
    are diagonal lines and the sides of the screen are bowed.The television then
    shuts down and the stand by light flashes 2 times.

      E-W Correction fault--Possibly one of the diodes in the E-W modulator.

          Check the Horiz Osc cct. Possible Yoke Horiz coils defect. Not sure from your post of the lines are retrace lines or Horiz Osc off frequency lines.

                  Look for Horiz Osc crystal. It may me blue or orange in colour. Replace that, too.

                      Sony XBR-65X750D Horizontal lines bottom of screen
                      by ggil44
                      Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks,

                      Hello again everyone,

                      This is my latest mission, to try getting this Sony tv back to normal working order…

                      I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried...

                      Sony XBR-85X950G Gray horizontal lines and vertical picture shift diagnosis?
                      by noisykid
                      5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

                      Sony KDL-40V3000 - Vertical lines
                      by gpo23
                      Hello,

                      i order a t-con because i had bad colors on my SONY KDL-40V3000 :




                      With the new t-con the color are good but there are vertical lines on all the screen :




                      I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)

                      Is there a way to fix the vertical lines on the new t-con ?

                      Thank you for your help

                      SONY BRAVIA XBR-55A8H - White horizontal lines / red LED flashes four times
                      by thstuff
                      This "free from a friend who was going to recycle it" SONY BRAVIA XBR-55A8H arrived with the bottom center RED LED repeating a four flash pattern. It was treated with kid gloves and was reported to have "just gone dead" and the OLED panel has no dents in the metal frame or cracks.

                      Thread https://www.badcaps.net/forum/showthread.php?p=1091829 helped in proceeding as follows:
                      1) Unplugged, then plugged set in while holding the remote VOL- and Power to factory reset.

                      2) Waited 30 seconds, then pressed remote Power button and "Select language"...
