I've got a Tosh tw56x81 and I had been throught the avia calibaration stuff many times. But lately I've notice a slight burn in where the 4:3 letterboxing happens. I just went to the avia disc to try and figure out what may have gone wrong. When I was testing the white balance (contrast) I have a tough time on the Tosh because the menus for the ajustments can't be removed from the display and the display covers the grey steps at the top half of the image. But, on my disply I NEVER see any blooming. White on the bottom half of the screen gets brighter and darker as I adjust up and down. The power supply appears to be pretty good to, there is no bending of the lines on the sides. So, how do you make these adjustments correctly in this type of an envrionment? Are there any helpful hints you may have? Also I'm a bit pissed at Tosh for the "reset feature" on the remote which when pressed bumps your contrast to 100 and all other values to 50. Contrast at 100, that's a sure fire way to kill a display.
