I have a Rear Projection TV, 50EX16B, Chassis AP52, I have replaced the STK4274 (3) due to convergence problems. There was a startup problem so I replaced I901 (STRM6511) and all is fine. What I have now is all 5 Green LED's on indicating that all circuits are fine but the Red protection LED is on as well. The Video/Sound appear fine, although certain features on the remote control On/Off do not work form time to time . I thinkk the problem is around I901, I have checked caps, resistors, zeners, all seem to check okay. I don't have a service manual so any help would be appreciated.
Thanks
