I have a 10 blink problem. Below is the system setup. I've read the 10-blink can be multiple issues, and from my debugging I think I may have multiple problems. Here's my setup:
2 Sources: DirectTv HD-DVR HDMI , PS3 HDMI
AVR: Onkyo TX-SR605. (NOTE: THIS MODEL HAS KNOWN ISSUES WITH THE HDMI BOARD)
Inputs: HDMI 1 input from DirectTV unit, HDMI 2 input from PS3.
Outputs: 7.1 speakers. HDMI output to Panasonic Plasma
TV: Panasonic Viera TH-50PZ85U. Input: HDMI 1 from the Onkyo. Speakers off.
Okay, here's the issue. Had no problems up to the last week. I recently added the PS3 about 2 months ago. I run the DirectTV box at 1080i, and the PS3 at 1080p. Earlier this week, I had been using the PS3 and when I finished, I turned off the TV and the PS3. I usually leave the AVR on at all times. When I turned the TV back on - the dreaded 10 blinking lights syndrome!
Problem: 10 blinking lights. I contacted Panasonic - they said it was either an unrecognized HDMI signal or an issue with the power source. Disconnecting HDMI alone and turning on/off the TV did not help. ONLY disconnecting HDMI, turning off the AVR, and disconnecting power to the TV for a few minutes worked.
This did fine up until yesterday when it happened two more times. This time, I had to disconnect the TV for a longer period of time. Seems to happen each time after using the PS3. Also, when the game loads on the PS3, the Onkyo switches between different multichannel HDMI and direct HDMI modes 3 or 4 times. Video signal comes through, but it's almost like it can't decide between the HDMI audio input. May be completely unrelated.
So after reading the 200+ posts on this problem on this site, I figured perhaps the PS3 is acting like the HTPC were. I bought an extended adapter and also plugged into the HDMI 3 port on the side. No dice.
Next, I decided to eliminate as many variables as possible, so I disconnected EVERYTHING (including the Wii component video cables to the TV) so that just the power cord was plugged in. Turned off the TV for 2-3 minutes, then powered on. The TV worked. I turned it off after 5-10 seconds and turned it on again - 10 blinks. Let it cool unplugged for 2-3 min, it turns on again.
Do I have multiple issues here?
1. It seems like a cooldown problem with the power board if I can't turn the TV on and off quickly.
2. The HDMI thing may be real as I seem to always get 10 blinks if I turn the AVR on BEFORE the TV. The TV works more often if I turn the TV on first then the AVR.
Panasonic concierge quietly listened to me vent about this. They are paying for the tech to come out this week (even though I'm out of warranty). I am fairly comfortable replacing boards myself (computer engineering degree from the late 1990's) but a little concerned about screwing up the TV and/or shocking myself.
Please let me know if you can help or had similar issues with a 50PZ85U.
