It's unlikely leaving the battery pack attached ruined the radio, unless it leaked and corroded the contacts. Be sure they're clean and bright. Double check to be sure the battery pack really is charged to rated voltage.

The battery select determines whether you're using a NiCd or Alkaline battery, I believe the "adjust" is used to put the radio into service mode. If there's not an "auxiliary power input" you can hook up the bench supply to, check the battery output for the voltages and polarities, and hook up your supply accordingly.

You should be able to get the keypad from Yaesu parts: \(714)827-7600You may be able to download the manuals at: www.mods.dk

Check the frequency step setting. If you have it set to 12.5kHz it's possible that's forcing the nfm mode.

Turn your VX-5 off, then press Band + HM/RV + TX PO and turn on.

You can probably find it on www.mods.dk - you may pay a small fee, but they have manuals for most ham radios.

The walkie talkie is the heat sink. So on extended talk times, it will get hot. So will the battery. If you run full power, it is only worse. That said, some batteries will become abnormally hot with use. Usually OEM batteries are higher quality cells and seem to get a little less hot. Never buy the cheapest battery for a handheld radio. Some are pure junk.

Yaesu offers the MH-34B4B Speaker Mic or the MH-37A4B Earphone Mic for the FT50 HT.Speaker Mic (Heavy / Standard Duty)Earphone Mic (Light Duty)Any ham radio store should be able to obtain these - if they are still in production / stock by Yaesu. Ham Radio Outlet aka "HRO" has stores nationwide and can ship direct.I hope this helps!

Carefully clean the contacts on the battery and the radio. The contact area is so small that the slightest amount of oxidation or corrosion will prevent the radio from working.

Carfully clean the contacts on the battery and the power contacts on the radio. I have had the same problem, and this fixed it for me.

figured out how to solve this, with the radio off, push and hold both up and down scan buttons, while powering the radio on. This will fix the problem.

You can order the parts from Yaesu or your local Yaesu dealer can do it for you.

Not enough power. The radio requires a steady 12 VDC input, or in a vehicle, 13.2 VDC. You did not mention if this is a 25 or 50 watt radio. I guess 50 watt. This occurs often when the wire is too thin for the amperage required. Get thick wire or the harness may not provide enough amps and it will get really, really hot! The wiring harness from Vertex is the best one. If you have checked all your wiring AND the power connections, it is less likely a programming error. Let us know!

HI, I think the best is to make a reset to the unit, regards, Daniel https://www.rylwy.com/diy-magnetic-loop

Is it plugged in? Is not the server/plug that connects to your cable turned on? See if your power charger is turned on first. If it's not on, your machine might not be on either.
