Hello Everyone, I have an older 57" Hitachi Projection TV (2003).
The Model # is 57TWX20B, The picture & sound would go out at times and would happen more frequently. Now I have no picture or sound,
I had a problem about 5 years ago and it turned out to be the flyback transformer. I replaced it with one from Tritronics and it was working fine till recently. I cannot remember if the sound also went out the last time.
If anyone knows if the flyback powers the sound board please let me know. If anyone knows where to get parts from also, I would appreciate it.
Thank You, Joe
