Re: Sony KDL-48R550C, need comments is it Panel FAILURE?

its not PANEL failure, just update your firmware, problem solved for me, but the problem is how to update your firmware with display like this? (Appear 1 second and Disappear), this is my way and I hope work For You:

1. download your firmware from sony, locate it in root directory of USB and plug in to USB 1
1. pull out Main Fuse (12V) on Tcon board
2. Replace it with Push ON switch (With Cabel)
3. plug in AC adapter and press power ON Switch
4. immediately press and Hold this Push...
