    Insigna NS-L24Q120-10A(verticle lines, craigslist scammed)

    Hello everyone!

    I was scammed on Craigslist. I my greed of a great deal it was too good to be true. So needless to say when I got this 42" amazing deal home and plugged in, vertical lines and no picture....well when I press the menu button or volume button you can see it pops up on the screen, but it just stays in the vertical line view.

    So since I feel I can fix most thing I went to take this thing apart, only to come and find it has already been taken apart! It was missing screws for the case and when I got the back off, the T-con board was taped on chase, not a single screw in it. Everything was plugged in and tight. I looked around for bulged or leaking caps and found nothing. I don't know if the previous jerk replaced the T-con board or just opened it and took it out and gave up. Below are links to pics front and back:

    http://tinypic.com/m/hx0orc/2 - The yellow part on the screen in when I turn up the volume. This is also with the tv on about 2 min.

    http://tinypic.com/m/hx0orb/2 - 30 sec after turning on the set no, buttons pressed.

    http://tinypic.com/m/hx0ork/2 - Power board(supply)

    http://tinypic.com/m/hx0ord/2 - Main board

    http://tinypic.com/m/hx0orl/2 - T-Con Board (are the missing screws a grounding point?)

    I've done some reading and watched as many YouTube videos as I have found, but I want to make sure before I start buying things on top of the money I paid for this broken TV already.

    Any help is appreciated and I'll answer all questions as fast as I can.

    Someone obviously tried to change the T-Con board and it did not fix it. (unless they had a bad spare to try) Seeing the vertical stripes I would say its the pannel or tab bond IC problem. Even with these normally there is a picture. Have you tried connecting to HDMI ports? Have audio? Maybe you can salvage some boards so the loss will not be soo bad.

      I have not tried an audio source since I took it apart pretty quickly. I'll out the front panel back on and find and auto source to run on it. I'm not sure the guy ever changed it, he could have just took some stuff apart trying to see what was what. Do you think the lack for it being screed down can cause this issue? Not sure of those screws are a ground of some kind. I'll try the audio in the morning. That's for the response.

        Hello forum folks!

        So I plugged my Roku into the HDMI plug and fired up the tv. The picture is clearly there as I can see movement when I touch the roku remote. As I turned the vol all the way up and no sound was to be heard from the roku as I moved around the menu.

        So could this mean the Tcon is fine and the main board is poo poo?

          This is why I always meet at private residences when transacting over trading sites... Did you do this?

          I would say 90% certain panel is bad. I do not think it can be fixed. I have seen this before. Can sometimes be tab bonds but not always permanent fix. Try lightly twisting TV frame, does picture appear?

            No I didn't them at a place with power, I took a gamble and lost.

            I tapped an wiggled the tab bonds but nothing changes. How can you tell it is the panel vs a board? If the panel was bad, wouldn't I get sound still?

            Thanks for your responses!

              If you can't select an input source, you won't be able to choose one with audio, or see if it has been set to zero volume, or home theatre output. Had that fool me before. The effect is pretty characteristic of a panel fault, there's a small chance the t-con is causing it, but I wouldn't bet much on that.

              Some people are bastards.

                Driving a Sharp TCON/panel with a universal main board
                by advant
                This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

                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...

                Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
                by Daren87
                Hello everyone,

                I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

                TCL 50S535 bad tcon or panel issue?
                by x_orange90_x
                Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

                Lg TCon test pins for screen test
                by alltvrepairs
                Hi,
                i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.

                Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.

                Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?

                Appreciate your help....
