    LG 43SM5KB Backlight working but no image

    Good day! Does anyone here familiar with the TCon from LG: 6870c-0532b. The problem is that the TV displays no image but backlight and audio from TV is good. I have checked the 125V/2A fuse and it reads 160~180 ohms. Could it be that the only problem is the fuse? Any suggestions and recommendation is highly appreciated.

    Note that it is only my first time to try and troubleshoot TVs.

    Thank you and have a nice day!

      Get deeper on the fuse pressing probes and twisting, retest the fuse..

          So check the voltage relative to ground at the input of this fuse and at its output.

              Asus G513QE keyboard and backlight not working
              by ktmmotocross
              Have this Asus G513QE with keyboard, keyboard backlight and Led backlight not working. other works ok.
              i measure all voltages ok on keyboard, KB backlight and Led backlight. looks like a kbc error.
              but as laptop works i think it cannot be bad. maybe its FW. have anybody some hint for this?

              Finlux LED backlight not working
              by stoian_93
              Hello guys!
              My Finlux TV backlight stopped working. I disassembled the TV, saw I don't have the tools to replace the backlight and assembled it again without replacing anything. So then the backlight started working again.
              A day after it is also not working.
              I decided now to remove the back cover and get the output voltage to the backlight. I placed the TV facedown and connected to the mains, so - nothing. I disconected, removed the cover and connected again to the mains and then the backlight lighted again. So strange.
              Output voltage when light is 66V.

              Which fuse is responsible for backlight on Lenovo Thinkpad T14 Gen 3
              by Attila Jamilov
              I upgraded display from HD to UHD recently, and I think I did everything right, battery was disabled in BIOS, and removed, yet the screen has no backlight. Both the old and new display behave the same way. I checked the motherboard and I see the fv1 fuse, and a fv2 spot for a fuse, but it's missing. Does anyone have any information on whether fv2 is responsible for backlight, or why it's missing? There's a schematic posted somewhere on this forum, but I can't view it as I don't have the hardware right now, since the laptop screen is broken and I run Linux.

              Also from further search...

              Philips 43PUS8550 no image, backlight working
              by pseudorc
              Hi,

              Checking voltages at TCON
              Vin 12 V ok BUT ALL OTHER VOLTAGES 0

              VGL1 0
              VDD
              vcc19
              VGH 0


              when connection to Left half screen cable disconnected - then other half becomes white and voltages shows down below
              VGH 27.96
              VCC19 1.89
              HVDD 8.31
              VGL1 5V
              VGL2 3.8

              TCON board has been replaced with similar (bought from Ebay)

              Is this LCD panel issue ? the parts showing parts no is lg 6870s-2704d


              Many thanks...

              Yashi All in one model AY62409 (Quantum S 24'') no image (backlight works)
              by zaurus81
              This chinese all in one computer gives an image when connected to an external vga monitor but only the backlight with integrated monitor (no image). Initially I thought it was an edid problem on the eeprom of the screen but then I saw that the monitor works correctly with another identical motherboard (model th410-d4, read by bios). Unfortunately the motherboard is chinese and has no brand or codes on the pcb. The format seems ITX. Nothing can be found online. The official yashi site provides drivers but not the bios. The electrical diagram is obviously unobtainable
              The board is equipped...
