I have a Yaesu FT-26, after replacing the backup battery, the unit does not work, nor transmit or receive.
Reset as indicated in the user manual does not produce any effect.
There is another type of reset more from those two of the user manual?
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Initially and the simplest probably would be to use the units without enabling the CTCSS or any form of encoding (turn this feature OFF). In the meantime, will check the specs and post if anything concrete comes up.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.

Thanks 4 your advice.
I left the radio w/o any batteries (the only battery is back up memory battery) in that time, and when I try the radio I used new batteries. The power supply for the radio is build in (uses 30 amperes switching power supply) and I have checked that the power supply is in a good condition. I suspect that PLL unit is not working so can't oscillation to generate frequencies.
The problem with sending the unit to the factory to be serviced is not worth (cost > benefit/ radio value).
Do you have another idea to help me? Please.. Thanks

I have a Yaesu FT-415 and the same problem. My original battery is a SONY 1220-VJ2H (solder tabs, blue insulation on the outer edge and two stick-on paper insulaters) and is soldered in to the Control PC board (mounted vertically). I'm going to get a new battery and hopefully am brave enough to get the soldering iron to the board. It looks like you have to unsolder the board from the speaker to lift it up enough to get at the solder tabs on the battery, luckily I have access to a Pace soldering station with a vacuum pump. I'll hopefully try this next week and get back to you all.
