Not that I have found and I have the 34HF81 service manual. However the measured red push on my set is very low (well under 10%) compared to other makes so its not an issue. By the way, if you would like a copy of the Toshiba 34HF81 service manual and schematics on downloadable PDF files, I can sell them for $20 from the expensive CDROM I bought.
I don't remember the exact percentage, but the red push on my 34HF81 is only a few percent. Oddly enough turning ON the "flesh tone" setting DROPPED the red push a couple of percent, exactly the opposite of what I expected. Green and blue didn't change. This was tested with the Avia DVD and filters. Anyway it's way less than Sony, Mistubishi, or many other brands, and I don't find 2 or 3% of red push to be objectionable.
