    Sanyo - dp32640 - No Video, Green light on, Back light on.

    Hello everyone!!

    My name is larry and i just picked up a Sanyo dp32640 flat screen that does not currently work. I've had good luck in the past repairing blown caps. I fixed my current tv that way. But this one has no visible bad caps or parts so I'm kinda stumped on what todo.

    The tv is a Sanyo dp32640

    When i hit the power button the green light turns on and the back light kicks on but i can't see any picture. Playing around with buttons i was able to get some audio but still no video.

    Thanks in advance for any and all help

    Check for voltage on both sides of the tcon fuse (usually 12v), its located just above the bottom left corner of the lvds connection labeled F1. A new tcon can be had here for under 30$, if you have voltage but no picture check lvds connections are in and tight.

      That sounds fairly easily ill do that when i get home. Thanks for the tip i will report back with pictures and results so maybe i can help someone else. As i did not find much info on the model on google or other sites.

          Could it be FL1? I did not find F1.

                I took apart and put it back together and it worked. At first I got some weird colors like red in place of black but I gave it a light tab with my hand and it fixed it lol.

                  Congrats, sounds like a loose connector was at fault.

                    I have this same tv someone just gave me... Light green when hit power button, I can't see any backlight but can see a quick blue flash up top from behind, Looks like around the tcon board.... Green light stays on till I hit off button
