I have a Mitsubishi tv model wd-65c10 set on 3d and DLP link on, I am using a Panasonic 3d blu ray model dmp-bdt220 set on checkerboard. I purchased Excelvan DLP link 3d ready glasses model QT0000101 and charged them completely. My problem is that the glasses do not stay in sync. I flash from white to black and I am always having to push the button on the glasses to get them back on 3d. Does anyone know if this is normal or am I doing something wrong. Help Please!

Is this happening when you turn your head or are you sitting far from the center of the screen ("off-axis")? I ask because the glasses sync on a white flash given off at intervals that is incorporated into what you are watching on-screen. Turning your head, looking up or down, or sitting too far off-axis can interfere with the glasses' abilty to see and trigger on that flash. Your hairstyle may also be interfering by partially blocking the sensor on the glasses.

That is a little far but should still be in range. Try sitting a few feet closer and see if it makes a difference. FWIW I sit about 6' away from my 61" set, and lose sync at around 9-10' with DLP link glasses.Make sure the room is dark and that there are no light sources nearby throwing off the glasses. When I get light interference this little trick sometimes works: take a small piece of black tape and cover half of the sensor on the glasses. Sometimes the glasses let in too much light into the sensor and it makes the glasses loses sync. This trick works very well on my glasses if I watch something during the day where there is more light in the room.

The player's location doesn't really matter, since it's the TV that is giving off the sync pulse. If you drew a line straight out from the center of the TV to your seating position (I assume it's a couch), are you sitting on that line, or far to one side or the other of it? That's what I meant by "off-axis".

Wow. Good info. I've never used DLPLink glasses, so was unaware of extraneous light sources interfering with them.

So if I turn my head and lose sync, should i then push the button on glasses to turn them back on or will they just sync back once I am looking at tv again? Sorry for all the questions, just new to this and I LOVE 3D :-)

Yes, that's what I'd do. Regarding moving your TV, as long as it's angled to point straight at you, you should be OK. Some displays have problems with color shifting as you move off axis. If your display does that, it could make the white flash the glasses are looking for appear as a colored flash and they may not pick that up. Of course, there's always the possibility that your glasses aren't that robust. Hopefully, that isn't the case.

On mine, if I look away and lose sync the glasses automatically regain sync when I look back at the TV.
