[QUOTE="pwatts, post: 835316, member: 146"] Presumed that it's the dreaded Onkyo bug, it can be fixed with reflow but it just buys time and can just happen again as the problem is due to a defect with the actual metal of the balls of the BGA chip. Onkyo kept dishing out new HDMI boards with the same buggy chip while waiting for TI to bring out a silicon revision, therefore the only reliable fix at component level is to use the latest revision DSP from TI (which is only OEM-available) where the bug was fixed. I did a reflow and x-ray of such a board where it was pretty obvious. Reflow is worth a shot since the unit is mostly useless without it, but it's not a permanent repair. [/QUOTE]
