I have the PTA507 in combination with the 55PFL5507H.
When 3D is active and the glasses are turned on it works perfectly for a short time.
After this short time the glasses are disabled (not working anymore).
I have to get really close to the TV and sometimes it works again.
As soon as I sit back in the chair the glasses stops working again within 10/20 seconds.
When sitting back in the chair it's only 3 meters from the TV without any obstructions between the glasses and TV.
I am sure it should work with only maximum 3 meters from the TV.
It seems however it's NOT !!!!
Something broken ??
Please advice.
Thx,
Edward
