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.
