Intro plus help for Medion MD33332 Now fixed
OldLes:
Kieth, many thanks for your replies. I found a link to the 1084 on RS website:-
( http://uk.rs-online.com/web/c/?searchTerm=lm1084&sra=oss ) but the choice of device variants left me confused. What I will do, maybe tonight, time permitting, is to power the set up again, check the voltages on both the suspect and adjacent good 1084, and try to decide which version I need.
Maybe one of yours would fit the bill, let me measure first.
I will try to get a scope on it and look at the ripple in view of your earlier comment; what is the maximum I should tolerate would you say?
Jordan, your references confused me. Google just leads me to an IC, not a chassis, or am I missing something?
Keith:
I have a similar chassis in at the moment!
The type can be identified by the number after 1084, i.e 1084-33 = 3.3v, 1084-50 = 5v e.t.c. No number after 1084 will probably be a variable type. Also if pin 1 is connected to ground it will be a fixed voltage type.

At the end of Jordan's post you will see what looks like a paper clip, click on it and you'll get the service manual for this set in pdf format which opens with Adobe reader.
Hope thats clearer m8. :13:
