Is the antenna the correct one for your environment? Do you have the antenna pointed at the stations you want to receive? Use antennaweb.org or tvfool.com to get an idea of the location and likely channels you can receive at your location. Antennaweb assumes an outdoor antenna but is very conservative in the list of channels you can receive. (These may match the limits of the indoor antenna.) TVfool lists the stations and the appropriate antenna that will likely receive each station.
Tall trees and buildings will block the signal. Get the antenna as high as possible. Move the rabbit ears and UHF loop to maximize your signal strength. Then make sure the TV is set to use the OTA tuner (ATSC for digtal stations). (That may mean changing the source in the setup menu.)
Then scan for channels. Move your antenna or parts of it and rescan or edit the channel list. (For some TVs there is a weak signal setup option that will let you manually enter the station number (including sub-channel). Then it will provide the signal strength information as you move your antenna.)
I hope this helps. An amplifier may help you bring in weak stations with enough signal strength for the tv to see them.

Look for open resistors near by, if the 2SC1969 shorted it has taken out one or two parts, also check for open foils on the printed circuit, beyond this a circuit diagram is needed.

Check with ICOM on their web site or with HAM RADIO OUTLET, a large chain in North America---you may find a source that ships overseas or even one in Manilla.

Not sure what you want.....VHF band ius approximatly 130mhz to 175 mhz..... in that VHF band there is a commercial VHF band aprox. 155 mhz to 175...... the amateur radio vhf band is aprox. 135 to 150mhz.
With amateur radio, any freq in that range can be used...... with commercial radio the FCC cangive a company any freq. in that range also.
If you are looking for FRS/GMRS frequencies they are UHF freqs not VHF.
So I'm not sure exactly what you want......sounds like you might want to program in FRS freqs into an Icom amateur radio. If thats the case you will need an Icom that will do UHF freqs.
