    Sharp Lc-42SB55E problem

    Hello,

    I have this tv. One day i turn it on it was like all buttona all presed, tv just jumps thru menu, volume is going down automaticly.

    I open it and disconnect side buttons. Then i turn tv on and it was normal, but o dont have commens on tv. If i press button on remote, light on tv for remote blink but nothing happends. If i connect side buttons back, volume goimg sown again and inpust source changed automaticy.

    I chec the mein board and buy used one from ebay. The boards have boats the same number 715T3251-3 (WK:827). But this whis i bougt was from 26” inch tv with the same numbers on it.

    I replaced the board and turn tv on. Side button an IR remote dont work. Input is on HDMI 2, whic i need because i have conneted only on hdmi, tv is in living room and reciever box is connected with hdmi.

    Problem is when image shows. The image is like pattern, i have two image on screen (image and half) one at top and half one at bottom. How can i resite image to fit screen.

    Thanks

      There would be other numbers that should be matched but most likely different from your original board. You have the wrong Main Bd and so the software would be different for a 26inch TV.

          715T3251-3 is the blank circuit board P/N not the stuffed circuit board assembly P/N.
          Blank board can be stuffed to make many bard assemblies for many model of TV's.
          You need to match the barcode numbers.

                  70LE660U dark cloud or black screen with sound.
                  by Rozp
                  Hello Everyone,

                  This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.

                  I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area....

                  samsung ua55es6800 - no image
                  by shlomim412
                  hi
                  having problem with samsung ua55es6800

                  tv had backlight on, sound working - responds to the remote control but no image.

                  check tcon board - had 12v in but no other voltages present.
                  when disconnected left ribbon cable - got back voltages and half image with lines and distorsion

                  when leaving only left side connected - again no voltages and no image.

                  put a tape on all (cd?! lines) on the left ribbon cable and got complete but distorted image (horizontal lines).

                  kept trying to block less pins on the left ribbon cable...

                  Display problem on Kryster KLED403DC TV
                  by jeangonbay
                  Hello, I will explain all the steps I took:

                  TV model: KRYSTER KLED403DC
                  Mainboard: TP.SIS231.P83
                  Panel info: TY390LK02-ACW1 / V390HJ1-XC01 / V390HJ1-P02 REV C1

                  So, at first the TV stuckl on the KRYSTER logo, a brand which seems to be sold, apparently only on Reunion Island, the place where I am located.

                  So I looked for dumps compatible with the motherboard, which I could inject via USB key, with the file name SISEU23X8M.bin.

                  Several worked, but the display was inverted, so head down, and I did not have a remote control available at...
