I have an IC-V8 (it was in my "radio cabinet". which hasn't seen any use in some time (4 years or so). I charged the battery pack. The radio will not turn on. I did a reset (press squelch & clr at the same time and while doing so, press the "on" button for a second. Nothing. H-m-m-m, so perhaps the nicad battery pack went bad. So, I took out the six double "A" battery holder and inserted free Duracells. Tried the reset again No luck, radio will not turn on. Is it possible that somehow in the past I "bricked" the radio? (Although I can't imagine how). Any suggestions or thoughts??

I don't have a service manual for that radio, but it is possible that it has an internal rechargeable coin cell on the circuit board that retains memory and makes the radio remember how to radio when the big battery is dead. It is possible that the radio sat for so long that it's given up.
If it has one, replacing it will sometimes revive the radio. It won't be easy to get to, though, and would require disassembling the radio and possibly a small amount of soldering.
Maybe someone that has one of these radios, or a manual for it, can enlighten us all.

No coin cell in a V8. But, if it's been sitting, a couple of possibilities:
Corrosion or dirty power contacts on the power button. Open her up, continuity check on contacts (they are on the side of the radio PCB). Clean with de-oxit or similar stuff.
If power switch is good, start tracing the DC rail. Assuming the EEPROM isn't baked, my guess would be a small SMD cap or something has gone open.

Many older Icom radios require an additional key to be pressed after a battery is replaced or be removed for some time. I have several models that I purchased as "Dead" and revived them with Cpu Reset - Icom IC-V8 Instruction Manual [Page 32] or similar additional key presses.
Thank you for the prompt response,,,Out with the soldering iron!
Thank you. Tried the CPU reset several times. No luck.

Cool your iron. Read what @MTS2000des said. No internal memory battery. If you want to tackle it, start checking the DC buss on the radio like he suggested. This might be a simple fix.
