I'm using my 48PFS8109/12 with a Onkyo RT-538 AV Receiver, which, like the tv is HDMI 1.4 compatible. the television remote recognizes the receiver via HDMI while adjusting the volume, but only very briefly. the transmission stops before you actually get to adjust the volume properly. you have to use the receiver's remote to further adjust it. after that the tv remote works again briefly etc. for instance: volume is set to 25db on the receiver and needs to be adjusted to say 30db. the tv remote will adjust to 26db or 27db and stops. further adjustment needs to be done withe the receiver's remote, after that the tv remote wil work again for +2 or -2 db. have you got any idea how to solve this?

Thanks in advance
