Problem was with a bad horizontal linearity coil, L501





Hi all,
This set has a high pitched squeal when the chassis is torqued and when it is 
in the set.  If I twist the set the squeal will com and go, however, when I 
press on the circuit board near the SMPS while twisting the squeal 
disappears.  The set has had this problem for a long time and was serviced by 
a SONY Service Center last year.  They couldn't find the cause of the squeal 
and placed a wedge under the chassis. Any help would be appreciated.
