Recently I lent my Sony Watchman to a friend and gave him the wrong
power supply.   The poor TV got 15 volts instead of 6 volts and the
polarity was reversed.   Apparently the TV was not protected against
this with a diode and so some serious damage was done.   The visible
effect is a surface-mounted device that is now mostly carbon.   It
would seem that the damage might be predictable and perhaps fixable
if one had a schematic.   I don't.   Does anybody out there have access
to service information such that they could help identify what might
have happened to this TV?   Thanks in advance.
