    Westinghouse SK-32H240S vertical lines and fade to black

    Someone gave me a Westinghouse SK-32H240S TV/DVD combo unit. When you power on the unit you see the Westinghouse logo with a bunch of rainbow vertical lines, then you see it searching for a signal and slowly the screen fades to black.

    Backlight inverters are still on (so I don't think this is the "2 seconds to black" issue in other threads where the backlight turns completely off?) and you can still hear sound from the source. But the screen is black with some gray lines down the center (where the vertical lines were before).

    Do you think it's a defective T-Con?

    Thanks,
    --Dave

    (I attached pictures representative of what my boards look like from ones I was looking at on eBay. If you need pictures of the ACTUAL board in my TV let me know and I can get it)

    Try having cables between TCON and the LCD panel connected one at a time to see what you will get on the screen.

      Will do. In the meantime, here's a picture of what it does with both T-con cables attached (attached). And a video: http://******/2tC4ofh

        Ok, I tried unplugging one cable from the T-Con to the panel and then the other. Here are the two photos of what occurred.

          Any thoughts based on the pics? I ordered a new T-Con just to try it. It was only $5.99. Should be here Monday.

            I am leaning toward bad panel.

              I would have to agree. Try the T-con though, there is a small chance it will fix the issue. Can't see it being anything but T-con or panel.

                T-Con did the trick!

                  Next order of business - the DVD drive is kaput. The cheapest I found from an online seller was $32 including shipping and I don't think it's worth buying considering the whole TV is probably worth about $60. Anyone have a spare they're willing to part with, or a cheap source? Thanks!

                    Never mind. I sold it without the DVD player

                      Screen Display Vertical Multicolor Lines
                      by Stanley1843
                      Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

                      Colorful LCD Vertical Lines on Samsung ue55es8090
                      by Falki
                      Hello there, ive recently found an older 55inch Samsung SmartTV.
                      Sadly it has vertical lines at the left and one line in the middle-right.

                      I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
                      I have factory resetted the TV as well but also with no luck.

                      I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..

                      A similar issue has been posted as well but also with no actual response ...

                      Help. Sony kd-65x85dj vertical lines
                      by visionbluedemon
                      First. it has no picture at all. i solved it by covering the ckv lines using tape to to block the connections

                      Second. now has picture but with vertical lines that follow the image. tcon board ic overheating

                      tried blocking LC lines too, but same results




                      is it lcd panel issue or tcon board issue?...

                      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

                      Thanks for offering your assistance with this. I'm an electronics enthusiast with moderate level of competence (have a decent lab with two power supplies, microscope, DSO, hot air, good iron, can competently work at a component level on SMDs, design and solder own PCBs etc). I really enjoying fixing things and learning new stuff so took up a free 58" LED TV and have been googling and watching Youtube videos to see if I can fix this! I am happy to go down to individual component replacement/strip replacement etc - it's all in the name of learning.

                      The issues are as follows: the...
