Hi all

 

I have a barcrest pacman powerup that has has been working great for over a year until tonight.

 

I went to switch it on and it didnt boot up apart from the cashpot sign at the top..when i opened it up it was saying mpu battery low

 

Here is a video of it

 

 

Is this an easy fix? bare in mind i am useless at things like this and if it involves solder etc i know it will be out of my depth.

 

Thanks all for any help

 

Chris

When was the last time you had the machine switched on for a decent period of time, 2 hrs plus?

[chris_newton]

it was on all day saturday, i always have it on every saturday all day

[Mavroz]

Can only guess that the battery has/is failed/failing or if they use a rechargable battery,a transistor on the charging cct has become leaky...

 

If you don't know what you are doinf electronically, i guess the only option is to source a working mpu6 and have the program (rom) written to it.

[chris_newton]

I actually have the rom.. Could it be OK if I left it on for few hours?

[Mavroz]

If it is rechargable, it should charge back up ok.

 

I suspect (never having used MPU6) it is the same as mpu5 with a coincell (non-rechargable) battery that has to be changed.

 

Edit, MPU6 is a 3v lithium battery, so i presume it is a coincell (similar to the one in a car remote fob), so i am guessing it has to be replaced.

 

Someone more familiar with mpu6 will be able to advise you better.

Thanks I'll keep it on over night and see how it goes

If it is coincell, leaving it overnight will make no difference as the battery is non-rechargeable.

[chris_newton]

I understand that but just incase it is rechargeable

[chris_newton]

ok so my dad is quite handy with a solder!....first thing first what battery do i need? i have had a quick look on ebay and came across these 2

where exactly do this battery go? and if we manage to do that how easy is it to put the game rom back on? (i do have the rom zip)

 

Thanks

[Mavroz]

The battery will look similar to this i think. (The ones you have in your link are re-chargable)

It will have legs on the one on the mpu6 and be soldered into the board. You will have to get the exact number from the old one and source a replacement.

 

Unless you change the mpu6, i doubt you will need the rom re-flashing to the unit you have, just changing the battery.

 

Like i say, these are too new for me at this time, i think i have given all info i can give. 

Good luck.

Fairly certain MPU5 used a lithium coincell of the type which IS rechargeable?

[chris_newton]

So how do I find out? Do I take the grey box apart?
Sorry I meant black box apart, the one in the video

Yes. Take photos and we'll advise.

[chris_newton]

Do I need to take wires out of box to get to mpu?

You probably will yes. Unfortunately I'm not particularly familiar with MPU6 construction.

[chris_newton]

I will take a look tomorrow and take pics before I go ahead so any help will be Really appreciated.

Thanks again

MPU6 uses a CR2032 Lithium coin cell battery which is not rechargeable:

Thank you for the confirmation. Very different to the setup in MPU5 then. And very quick and simple to replace.
