While adjusting the "rabbit ears" on the TV one of them touched a floor lamp. The lamp wasn't on, but it's a 3-wire lamp so its exterior is grounded; there was a brief spark and the TV quit. I took the back off the TV and replaced the fuse on the PCB; unfortunately, there must be a bigger problem because the new fuse blew immediately as soon as I pushed the power button.

Re: Sparking rabbit ears
If the fuse blows the instant the power is switched on, there is most likely a heavy short in the primary side of the power supply. This could be the rectifier diodes or the switching transistor (or IC). If you do not have experience identifying and replacing shorted semiconductors, allow a qualified tech to handle it for you.

You will once again, purchase a converter box to receive an over the air channel. I don't think you will have to really worry about using an over the air mode on the TV. It may be in the menu, but will work otherwise after being placed on channel 3 to receive through the converter box. The rabbit ears will be connected to the converter box itself.
Your TV is old enough to have not only screw terminals for the antenna, but it sounds like it has separate UHF and VHF terminals as well. Pick up a 75-ohm to 300-ohm adapter (available at Radio Shack and probably most other places that sell TV's and antennas). This is a small cylinder-shaped part with a threaded antenna connector on one end, and a flat wire with two terminals on the other end. Connect the cable from the converter box to the round connector, hook the two terminals to the VHF antenna screws on your TV, put the TV on channel 3 and you'll be set.
You should also pick up a new antenna designed to work with digital broadcasting. If you use the old rabbit ears you were using before, you will probably not pick up all the channels available in your area.
What are you using to connect the rabbit ears to the tv, a 300 to 75 ohm plug assembly? it may have sprung the contacts in the rf socket of the tuner.
or The tuner has malfunctioned,
It may be switched to the wrong source as some tvs have more than one tuner input.
The "Horse Shoe Like Ends" on the leads are installed under the Screws marked ANTENNA and then the screws tightened. If No Screws then your Rabbit Ears do not hook directly to this TV. Is there a connector comming out of the back that is Threaded? If YES, then this is your antenna connector (R59) and will require an Adapter for the rabbit ears. Available at Radio Shack.
harvque- you can use rabbit ears to get the local free channels,but you will probably need to extend the wires and try to mount them outside.The main reason is because the newer tv's with digital tuners don't pick up as well as old school tuners,and the tv signals are not as strong cause they are usually boosted as the are wired in.Try this and let me know,I do have a few tricks for free air tv. cooltekFeb.18/08
