The IC-V8000 is a high power (75 watts) 2 metre radio, it will draw about 15 amps on transmit. Also you might want to make sure your antenna SWR is low about 1.5:1. If you are not receiving anything at all I suspect you may have an antenna issue and this will also effect your transmit as well as the radio will protect its self by reducing the output to almost nothing if the antenna has a high SWR. If you don't have an antenna analyzer check with another amateur radio operator they may know someone who does. Your local amateur radio club most likely will have someone who help you solving your antenna problem.

Reduced power may be due to high SWR.

Can you please provide the actual model that you are using so that I can check up on how it works.

No. Each radio is designed for the country of use and built at the factory that way. Cheaper to buy a new radio.

If the radio is made to be sold only in the US then the phase lock loop is disabled when your are trying to transmit out of the US band edges. Try looking up a MARS circuit mod for this model and it amounts to only clipping one end of a diode to enable the transmitter on all frequencies.

If it can receive some signals that are close to you, then the RF front end protection diodes are likely shorted. This would require someone with expertise in surface mount components to repair. Take it to a dealer and have them look at it.

It could be that you have a power supply problem as it seems to be that way with both radios. Linear power supply pass transistors fail quite often. Switch mode power supplies aren't much better. Their electrolytic capacitors are quite often defective.

I suggest you post this question on a Ham Radio web site.

It sounds like the grease lubricating the shaft has hardened. OR, as I have read elsewhere, the shaft may have been bent. You may need a new encoder but first, I would try a bit of Isopropyl alcohol to soften the grease.

Check Microphone settings and ensure volume indicator moves up and down when you speak into it.

When a device or appliance doesn't behave as per the instructions there is little doubt that it is faulty.

Whether the item should be repaired or replaced depends on various factors, though it is worth contacting the manufacturer in case there is special advice they can offer.
