        Yea, and unfortunately, there is no USB on the 52D... Only an SD card slot...

            Have you tried a different HDMI cord?

                    OK THis is wierd..

                    I went back to see if I could get the same setup (SIGNAL TYPE unghosted) on INPUT 5.. No luck.. No matter what I do, it stays ghosted..

                    And now 4 is back to being ghosted..

                    EDIT: OK I think I figured out why... If there is a signal, (IE an HDMI source is plugged in) the SIGNAL TYPE is ghosted... If there isn't any source plugged in, then I can select SIGNAL TYPE...

                        https://cdn.badcaps-static.com/pdfs/...ff74460ac8.pdf User manual check page 31, they seem to make it pretty complicated, select this select that etc.

                            Yea, that is pretty confusing...

                            Thanx for the PDF, though.. Can never have too much information..

                                Ya know what the absolute QUICKEST way to find a specific main board in yer stash of parts???

                                Order a replacement board.. :^/

                                30 mins after I ordered a replacement Main Board for the Aquos, I was putting my boards and such away to get ready for the weekend and the exact board I needed for this SHARP caught my eye.. Dunno how I missed it before as it was in plain sight..

                                Installed it in the AQUOS and the TV works fine now!!

                                So... From now on, I order replacement boards and then I will find the board I need in my stash..

                                    Good news, did you cancel the order straight away?

                                        Yea... Normally I hate to do that.. Once I place an order I hate not following thru.. But it was literally like an hour and at 0300hrs so, I doubt the seller even noticed the sale before I cancelled it..

                                        So, all in all, a win.. It's nice ta get those..

                                        Thanx again to all for all the help...

                                            I would like to revisit this issue..

                                            The replacement Main Board has seemed to develop the same problem but with a slight difference...

                                            I have hooked up a PS3... When I reset the video function of the PS3 and get low resolution, the SHARP displays the picture fine.. I then go thru the process of updating the video of PS3 to HDMI resolutions and again, the SHARP displays the picture fine.. I insert a game and then the screen goes black (changing video modes I am assuming) and then I get the video incompatibility error message again...

                                            Are there other factors at work besides the Main Video PCB?? Maybe the TCON or LVDS cables???

                                            Maybe I should try a firmware update???

                                                Hi, I'm just spitting out my thoughts here, so don't shoot me if I'm wrong...
                                                But, what if one of your source devices is somehow messing with your HDMI chips in your boards? It seems strange to me that the exact same thing happened to the second board. Except if this was a known fail point in those boards.
                                                Or maybe a somehow faulty HDMI cable (ie bad connector or something that when moves opens a signal or makes a short)?

                                                    Thanx for the reply...

                                                    I tried several different HDMI cables. And they work fine on other setups..

                                                    Like you, I find it strange that multiple boards can give me the same error... But what really bothers me is that if I.... like.. "sneak up" on the HDMI setup and build it up from low res to hi res, it seems to work OK... Until an in game video mod switch fraks it all up...

                                                    Gonna play with it today and see what I can come up with..

                                                    Thanx again...

                                                        It sounds like the eid of the tv is perhaps not set / read properly which perhaps causes / allows the video game to select an output that the tv can't handle. One way to check would to hook the exact setup to another tv that display the incoming signal characteristic (ie. res) and see perhaps what is being sent.... this will give you an idea of the transistions that are expected. In the past, res switching happened often during the playing of dvds/blurays where the intro and others were at one resolution and then switched as special features and the movie was played.

                                                        Also force a fixed resolution output from the system... trying low first and see what the result is, then move up... ie. start at 480p, then move to 720p, then to 1080i and then finally 1080p and see whats up where. Further, when hooked to a tv that works and shows a known display, check the frame rate along with the color bits.... these significantly impact the data rate and perhaps the cabling or end electronics are not up to snuff.

                                                            Thanx, Budwich...

                                                            About the only thing I can do of what you said was to slowly move the res up from 480 on up... Don't have any equipment to measure your other suggestions..

                                                            I am kinda the Larry The Cable Guy of TV repair..

                                                                Set the res at 480p and ran the TV off of a PS3 game.. Worked fine... Let it go for 20-30 mins and then reset the PS3 res to 720p...

                                                                Ran for about 10 mins and the display froze... Shut off the PS3 and the display disappeared after a few seconds..

                                                                Started the PS3 up again and got the incompatible signal error..

The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.

Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp...

                                                                                    Recently, and all of a sudden my 40” 4K Sharp Aquos LCD TV turned on with colors all smudged in some places on the screen that remain like that even without any kind of video source. I do have image but the colors are smudged/tinted/ washed out in patches as per defects. This to me looks similar to burn in but I’m shore this is not an OLED.

                                                                                    - I did the classic unplug and hold power button to discharge the caps but it didn't help.

                                                                                    The TV has standby power but no reaction at all to switching on or reboot steps, No flashing lights or response to menu button. All voltages on the power board are correct apart from missing voltage on pin 12 of CN7003.
                                                                                    There is 13 v on U7053 but no 3v signal to switch it on. I don't really understand whether the 3v should come from U7401 in the standby control area, or (as suggested elsewhere) from the mainboard via pin 12....
