At the diode output from the standby power transformer D001 is the 12.8v
source.Branching off below is a 5V reg Q002 that passes two 5.1 volt
sources,seperated by a coil L001.Lifted L-001 and short gone from the 5v
reg Q002.Short in the L001 5v line.Checked down stream. Finally removed
the micro IC001 and all the 12v and 5v voltages returned. Shorted micro
IC001# MN1873265T7F, about $20.00 from VanceBaldwin.com.Possible other
troubles(tuner?) but need micro to continue.
