I've read from several people who have had issues with their WM1Z or TA-ZH1ES and almost everytime, they have been replaced entirely and not repaired.I assume that Sony Central Repair ( U.K. ) can’t be bothered with the hassle & have just decided to replace ??
I have issues with the Volume Knob on my TA-ZH1ES and i was already told, that most likely the whole TA-ZH1ES is going to be replaced.
