I called Onkyo, Best Buy, Toshiba, and The online retailer I bought the Onkyo 804 from.
Best Buy was very helpful. They quickly set up an appointment for a guy to come out and look at the TV (although I doubt he'll be of any help)
Toshiba tried to be helpful, but ultimately the CSR didn't really know anything. They were unsure of the HDMI version # for the TV, but thought it might be 1.1 or 1.2. There's no way it was 1.2, as I bought it in 6/2005, so it's most likely 1.0 or 1.1. Toshiba had no firmware updates available for the 46H84.
Authorized Electronics, the etailer that I bought the receiver from, thought that it was a compatibility issue between the receiver and the TV (shocker), but couldn't offer me any helpful advice.
Onkyo was worthless. I was on hold for 30+ minutes, and the CSR I talked to was a complete tool. Very rude, and had no desire to listen to my complaints. He said they only issue updates for the receivers w/ NetTune capability, so I asked him why would my receiver have an RS-232 port if there weren't going to be firmware updates for it (since it doesn't have NetTune capability). This only peeved him off more, made him more unhelpful, and he essentially just passed the buck on. He also said he had no idea of when they would release firmware for HDMI 1.3 (if ever)
So, I basically have a tech coming out to tell me there's nothing he can do. Awesome
. I know I'm but one customer, but it would be nice if one of the companies wouldn't pass the buck on to the next (I have my fingers crossed about BB)
