    Can anyone tell me if there is an internal fuse in the IC-W2a? I've seen references to a fuse but can't find it in the service manual.
    Thank You

    Sorry, it's not an ICON, it's Icom.

    Hey, speak for yourself, I had one of those 25 yeara ago, and had not owned another HT until a few months ago, it is kind of iconic...

    I really hope I can revive it with a new Lithium battery, or find a blown fuse. It makes me sick that it could be unrepairable because the Lithium battery is dying and didn't keep the CPU memory alive. It is a really nice radio. Features are better, in my opinion, than my Kenwood TH-79A, as both UHF and VHF have squelch adjustments and I just like how it works. If I can't revive it, I'm going to post if for parts. I have 3 NiMH batteries, desktop and wall wart charger, AA Alkaline battery pack and a Diamond antenna for it. Is yours still working OK? Did you ever have to replace the Lithium battery?

    Have you tried a CPU reset ?

    Yes, I've tried the CPU reset several times. Nothing happens, and the radio won't turn on. I took the radio apart the other day, and found the Lithium battery. It was showing about 0.8V across it. I don't know if that could be why the radio won't start. I've charged the radio several times over the past 4 or 5 days, and tried the CPU reset every time, but it won't start. I have a Lithium battery on order, but don't know if that is going to fix the problem.

    Yes, That could be the problem.

    It sounds like it could be loading down the CPU clock voltage.

    It looks like the service manual posted above is very good. :)

    Good Luck.

    I got out of the hobby in the late 90's and back in a few months ago, so who knows who has it now or what the status is. I didn't know it had a internal lithium battery... I hope you can get it working. Aside from the bulky by today's standards battery packs, it was a great radio, or rather two radios in one box!

    If the Lithium battery is the only thing keeping the CPU memory refreshed, I wonder if there is a procedure for changing it. Does it need to be replaced fairly quickly so that the memory isn't damaged? I'm just hoping that it will work if the battery is replaced.
