    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.

                                          This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

                                          I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

                                          I am comparing them to a brand new one that I installed

                                          The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well

                                          Hi

                                          Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

                                          Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

                                          The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

                                          I have already tried replacing all of the...

                                          Hi

                                          I have an 820-2610-A motherboard that has no green light.
                                          I have noticed is when I do a SMC reset the light on the Magsafe blinks.
                                          From My understanding, the sys onewire circuit is responsible for the green light on the magsafe
                                          The sys onewire circuit on this model and others is more involved
                                          I was hoping if anyone knows about this and how it works, can reply and let me know
                                          I know this is an old model but I am sure there are people who still works on these or knows about them

                                          Hello, Badcaps is my last resort. I am the first owner of the monitor. I reached almost every repair store in my area, but no one even wanted to hear about troubleshooting an old CRT monitor. At this point, I have been trying to figure it out by myself, but I have no idea where to start or look for.

                                          I wish to know how to think and locate a failing component. I will put all my efforts to learn and contribute.
