    LC470WUD panel 10bit to 8bit

    Hi guys, i got a nice 42'' panel that in its specification needs 5 Even LVDS pairs and 5 Odd LVDS pairs, but i want to run it on 4 Even / Odd motherboard...

    Is it possible to convert it from 10 bit to 8 bit LVDS system? Ie, if i dont connect the 5th pair on the Panel will it produce a picture?

    I don't want to blow something up.... Thanks!

          Yup...interesting. Subscribed, since I must admit it's a bit over my head

              If all the other connections are the same then I think it may well work.

                  are you looking to use this with universal tv boards? If so, I have used this card http://www.chinaglobalmall.com/products/563331866923 (sourced locally, no experience with this seller, link is just for reference) with similar panel LC320WUD https://datasheetspdf.com/pdf-file/8...C320WUD-SBT1/1

                  the picture showed up and nothing blew up. I dont know yet how the quality of the picture is, my tv has backlight issues.

                      Interesting. I've run into this exact problem swapping LCD panels into LG tvs. Some are 8 bit and some are 10 bit and while the firmware allows a switch in the service menu, it's not supported... or at least nothing happens when you change it. Curious to see how this develops. Should have tried one of those boards in the link above.

                          Something fairly similar happened to me recently and it just popped in my brain upon reading this: I was messing around with some POS (no, really: point of sale ) terminals and their BIOS had an option for setting the LVDS type and I messed with that just to see what happens...can't remember what the values were, but one of them caused the screen to display two halves of one picture (one at the top the other at the bottom), while another one resulted in a mess of vertical colored bars all across the screen...I sh!t my pants at that point, I thought I broke it, because without any way of seeing what I was doing, I couldn't turn it back the way it was Thankfully removing the CMOS battery restored it, but still: something related to LVDS stuff which could've been actually what you're discussing about here.

                              Never had an answer whether 6ot4hr was successful or not.

                                  LG 49UJ6500 LCD panel lighter band that goes away
                                  by howardc64
                                  49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.

                                  Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on...

                                  by Storyteller12
                                  I had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.

                                  I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.

                                  I was trying to change the panel type in the service menu but don’t see my exact panel. Anyway to fix this or someone have similar experience.

                                  the clear picture is the panel type from the service menus on the nu6900. The other 1 is the panel type that was set for the q60r with the bad panel....

                                  Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
                                  by maneatingmonkey
                                  I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

                                  There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

                                  I came across a 50inch TU8000 that wouldnt start up properly (blinking stand-by light, backlights would cycle on and off).





                                  When i opened it up and removed the power to the mainboard the backlights powered up and everything looked uniform.
                                  When reconnected the mainboard but disconnected the flex cable to the panel i heard the TV startup with the intro sound.






                                  Later I checked for shorts on the panel PCB boards but could not find anything.
                                  When I took a look with the FLIR i noticed the 2 resistors...
