Hi,

I think this may have been on another post but i can't seem to find it again so starting a new one.

My R2 fails to start up altogether. I have checked the battery pack with a multimeter as suggested on other posts and the reading is good.

The only signs of life i get is if i push and hold the power button on the front, the lcd screen lights up and the blue lights in the legs turn on.

All the connections seem okay and i have tried it with mains connected and battery pack. I have checked the on off rocker switch and the symptoms above only happen when in the on position.

Is this a main board issue, is there anyway of checking where the power is getting lost?

Any advise would be appreciated.

What batteries are you using?

Do you have a link to where you purchased them from?

I’m getting the exact same symptoms as you. Just two LEDs on his legs and the one lcd panel when I keep hold of the buttons.

You had any joy dismantling yet? I’m going to try dismantle mine today. Multimeter readings look good.

Wonder if I should order a replacement MCU

I got these ones, they all test okay on a multimeter. And all charged to full using the supplied charger / tester.

Could you start your own thread about your R2 problem please so we dont get conflicting sollutions to either of your problems. What is the battery reading you are getting at the end of the battery lead and across all batterys please.
