Question about Toshiba 55H70 55" Rear Projection Television
I have the manuals for this Toshiba (TAC0069) but -as I recall from my days as a Toshiba Authorized -- Toshiba sometimes provided a Theory of Operation manual for a chassis series. Is there such a manual for this? Specifically, I want to understand the process of determining the sync rates of the incoming signal. How the circuit responds, switching the horiz and vertical rates.
Needs new stk 392-110

I read somewhere that there are eeprom values that if scrambled or lost can drastically affect the picture. I believe they are accessable and alterable through the service menus. I ran across a website somewhere (sorry) that had some values from other peoples sets. The values are custom per set -
