I have 2 or 3 TIUs each with a channel out.
They are all REV. L. One has the USB jack. I upgraded this one and checked the fuses, and all fuses are ok.
I don't know if there was some change in design, but for some reason I had the same channel go out on these 2 or 3, but my current tiu has had no such problem over years of use.
Anyway from what I recall from years ago there is a coder/decoder ckt or something like that whoch seems to be the prime suspect in this case. I a assuming this is not a part I can obtain and install on my own, but is only available by mth techs. Correct?
If that is correct are there any techs on here that would be willing to take this job to fix these? Any recommendations? If it's more appropriate please feel free to contact me by email, my screen name at yahoo.
I like the idea of having these as backups and feel like I better get them up to snuff now while still possible.
Thank you!
