Don , on this tv it's the 300 series and the chassis
is'nt marked anywhere. Anyway on going thru the old
archieves I noticed tips saying check d401 so I
checked d301 and sure enough that was my problem.
First time I ever seen a diode give retrace lines. By
the way are you the Don that haas the plans for an ESR
meter? If so I'd really apreciate a copy. Thanks for
all your time.
