Tommy,
I understand what you are saying...there are some problems you need a schematic
for.
Also, anyone relying on tips programs will not make it.
No tip program will have every fault for a model listed.
I think about half the time I look for something in a database, it is not there
and I have to find a print, or go to you guys for help.
I repair a lot of sets without a schematic and even more now without resorting
to
a database.
Anyone who goes to a tip program before troubleshooting, is only hurting
themselves.
I find all the new circuits intriguing and do my best to understand them either
on
my own, or from the help of you guys.

Yes, Jeff...I know about TriTronics...I use them daily. My argument is that
to truly troubleshoot a chassis you do need service data. I agree that years
of experience helps to repair a lot of electronics without pulling out
service manuals, however it seems to me that too many young technicians are
relying on data base and a quick fix to repair electronics today, True
troubleshooting skills are being overlooked. I am as guilty as anyone. I use
some sort of data base daily, it is necessary for us to turn out enough
repairs to keep our bills paid maybe even have something left over for a cold
one once in a while. The ESR meter helps but troubleshooting shutdown and
horizontal problems not to mention switch mode power supplies ...well service
data is necessary. Some of Hitachi's chassis have as many as 14 shutdown
circuits. I would find it difficult...no impossible to repair a chassis like
that without service data. Maybe I am just a little dumber that the average
tech....but I am what I am, and I need service data. I know there is a lot of
different opinions on the subject, but the only reason I mentioned it in the
first place is because I think the new and beginner technicians should
concentrate on troubleshooting skills.

Tommy,
Not necessarily.
www.tritronicsinc.com list many models on their site as well as OEM numbers
for
most parts.
This is an ideal site for finding OEM numbers.

Wow...only been at it for around 15 years, but I find I NEED schematics. As a
matter of fact ...I very seldom take in a TV if I don't have a schematic or
have access to one. Working on TV's without service data is guess work. Part
values are more critical today than they were years ago. Proper service data
is necessary just to get the original part #.
