They're either or cons or gross incompetents.

Ask in sci.electronics.repair, and post the model number. Sound
without picture is often due to a blown horizontal output transistor,
which not only drives the circuit that sweeps the electron beams but
also generates several voltages, including the 30,000V for the 2nd
anode, voltages for the electron guns, and even the CRT heater. If
bad, also replace any damper diode (necessary only if not built into
the transistor) and nearby small, high voltage capacitors. This
transistor is the largest one in the TV and likely mounted on the
largest heatsink. Authorized parts distributors may charge 2-3 times
what a place like www.mcminone.com does. Do you have any friends who
know how to work on electronics?
