Question about Toshiba 57H81 57" Rear Projection Television
I have replaced both stk392-110 chips and verified that all six resistors are still good but still unable to get a clear picture. When first replaced chips the picture was perfect after going through service mode and using touch focus. Then about a day in a half it started again with the red. Service mode would fix the issue then shortly after the red issue would come back until touch focus error would not let me correct it anymore. Need help as I don't know what I missed or need to do. Chips must be overheating but resistors are ok and I did use thermal paste with chips. I do have a question as to why the fuse resistors read 2.6 ohms when they are labeled as 1.8 ohm resistors. Resistors on board read 2.6 as well as new resistors. Please help as I really don't want to go out and buy a new tv right now.
