>The hot chassis used to be common in TV sets, but it went out when solid >state components took over. Modern sets have power transformers (usually >more than one) just like other pieces of electronic equipment. Most sets >have polarized plugs, though; these minimize shock hazards from leakage. Be careful: This is not necessarily so. Many solid state sets just rectify the 110 to create 170VDC which is used directly by the horizontal flyback circuit. Then they tap off lower voltages for other circuitry. This apprach is ultra cheap as it has no AC power transformer. Some use a switching supply which is non-isolated.
