Zenith SL3285BG pin cushion problem after replacing LX3201

[BobD]

Hi,
This set had the infamous pin problem with LX3201 blown. I replaced
the coil, transistor and diode in the pin circuit. The pic now has a
wavy picture, with the pin correcting itself on bright scenes, but
getting worse as the scene changes. I am wondering if the replacement
coil has a slightly different L than the original, causing the tuned
cicuit to be off. Anyone have the original L of the coil?
Any help is appreciated.

thanks,
Bob

Either that or you have a power supply that can not supply proper current to
compensate for the blooming picture. Monitor the regulated B+ to the
deflection circuits and see if it varies when going from a brite to dark
scene. Regulation should hold it +- 2 volts.
