Last time I swapped my Onkyo TX-SR706 head unit under the warranty and installed 12 cm fan to cool video upscaling cirquitry. One day I saw again singnal disappearing in fast image shanges on my plasma. I found my fan mis-placed and stopped. Clearly same overheating problem. Put fan correctly back to the right position, ontop of Faroudja chipset and image loss never ever happened.
