Comes on and plays OK until warm and picture fluctuated all sides as
scene brightness changes.Customer said it "rolled" but it's the
STR30135's regulated output fluctuating.Turn brightness down low and
voltage increases closer to normal.Output is sagging under load.
Looks like it's been worked on before, so:
I need to verify these PS parts are correct:
IC001 (STR30135?)
R005 (220K ohm?)
R006 (47 ohm?)
R004 (10K?)
R007 (5.6 ohm?)
Tritronics' model parts look up is incomplete.
Thanks.
