    Panel swap fail: Image reddish

    I had an LG Flatron L204WS with broken LCD panel and today I got a LG Flatron L207WT that missed a power supply. I took the panel of the L207WT and used it on L204WS. The display works but the image has some artifacts.

    Can you tell me what is wrong? Can the panel die like that? Is the signal board bad? I have no experience with this.

    I tried to take some images but it is difficult to show from the pics how bad the image is

      Are the t-con boards the same? If not, see if they will interchange. You;re using a panel with different numbers, so there's some kind of difference apparently.... The t-con board is what drives the panel, so if they are too numbered differently but plug in the same (check that very carefully before trying), that may clear it up.

        You have to get the LCD panels spec to compare the pinout of both panels.

          They look compatible to me. I upload photos of the 2 panels.

            Same pinout:


            Cannot find V.1, V.8 has the same pinout as VC.


            So I do not know why you have the problem.

              Double check all your ribbons on your t-con cable connections. I had a TV do this to me, except it was green and artifacting.... Reseated everything and it went away.....or perhaps thats why that monitor was parted out, the pane is bad in the first place.

                I disassembled and reassembled everything and the problem was solved. I also used tape to secure the cables.

                I was not impressed with the image quality, but after several hours messing with monitor controls and gamma through windows I find it acceptable

                This is going to be my everyday pc's monitor, replacing a 17 inch Samsung 710N that served me great :-)

                Thank you for your advice!

                  One Su'scon capacitor bulged.

                  I found out 1 week ago while I was aiming with my flashlight through the ventilation holes of the screen chassis.

                  I did a full recap:

                    When the set came in it was dead. Fuse was open primary side and the power mosfet was shorted. So I ordered a new power supply. Now it turns on, only displays "Hitachi" and then power off red and blue led flashing.

                    I had to modify the 0ohm resistors in the led backlight of the new PS like the original power supply.
                    Is there any variants on 17IPS71 power supply's?

                    65x900h with the panel from a 65x930d.

                    900H: model yr 2020, Samsung panel
                    930D: model yr 2016, Innolux panel

                    spec wise the panels are the same. the drivers and tcons are obviously different but what made me want to give this a try is that the wiring diagrams for the data signals going into the tcon for each tv were nearly identical. there are only a couple pins that i am unsure about and that is what brings me here.

                    the 930d has the DPS board where the 900h has none, however, if you follow the pins to the BM1 it would appear that the signals...

                    by Raulnn
                    good evening. I have put the panel model, because it is a generic Chinese tv. The symptoms are the following: The rear light turns on, but there is no image, 12v arrives at the tcon integrated in the panel. I have made measurements of vgl, vgh and vaa. They are not present but they all act as rectifiers except for vaa, which is shorted. my questions are. Do you know any quick method to know the capacitor that is shorted without having a laboratory source? How could I know the value of the capacitor once extracted? I can't find schematics for this panel. a greeting
