I for one,am interested in hearing about people's repair adventures.
I don't subscribe to the"Eeek! Repairing modern Electronics is way too difficult for little moi!",school of thought.
It is damn annoying that manufactures don't provide schematics----the usual excuse is Intellectual Property!
Most of the time they are using public domain circuitry,so the King definitely has no clothes!
Many companies seem to assume that you live in the same country as them,so you can pick up replacement PCBs easily,but if you live on the other side of the world,it is much more difficult!
It is even worse,if the original manufacturer either doesn't support the unit anymore,is defunct,or,as in your case, wants a "King's Ransom" for the board.
In these cases,there is no other option ,but to fix the thing in-house!
We had a Huntron Tracker at one of the TV Stations I was at.Only one Tech ever used it much,& he swore by it.
As far as I could see,you needed another good board to compare with,& if I had that,I could do the same things with an Oscilloscope & DMM,so I never spent the time needed to learn its use.(probably my loss!)
You shouldn't have to mess around like that to post or edit.I misread your comment & had to edit
this--I just hit "modify"& there I was.I'll now hit "Save" & I'll be back on the forum!
You can put your location in your profile,by Clicking on "profile" & digging around a bit,till you get the right page to do it.(I had trouble doing this,too,as it sometimes comes up wrong)
