game resets during every good game

[cooldan]

my Monster Bash is loadsa fun, but every time i manage to get on a good roll and the points start cranking up, it resets itself back to zero score.



any known issues, any easy fixes to try?



thanks pinheads!

Ahhh the old reset issue. Can be *lots* of reasons ...have a read here

Without going in to loads of detail ....a quick (and maybe temporary cure) can sometimes be achieved by reseating connectors J101 and J114 on driver board. Also worth doing ribbon cables.



Also Andy N always gives this advice below when asked about resets............ and Andy knows his stuff



Good luck soldier

A problem with BR2 is a possibility, but is in fact rarely the cause​

of most reset problems.​

It is more likely that there is a bad power connector. You need to​

carry out these checks first.​

Measure against ground on a DC scale the voltage reading at TP2 on​

the power board – the 5V test point. If this is below 4.9 V then you​

have a problem on the power board, either with the LM323K regulator​

or the J101 power input connector.​

Look to the right hand side of the power board and locate connector​

J101 which has red and blue wires. Remove and replace a couple of​

times. If it is scorched then it needs replacing. Re-check the 5V and​

see if any improvement.​

If still less than 4.9V then replace LM323K rectifier.​

If 4.9v or above, make a note of the reading and then take another​

measurement on the CPU on the top end of the copper coil you can see​

to the right hand edge of the CPU. If this is more than 0.04V less​

than the recorded reading from TP2 then the power connector between​

the two boards is at fault.​

Locate the short grey ribbon connector that joins the CPU and power​

driver board.​

Now remove and replace the connector directly below this on the power​

driver board. Do this several times, which basically removes​

contaminants and improves connectivity.​

This may well solve the problem, but it may re-emerge in the future​

and the connector may need replacing long term.​

If all the voltages are good, and you have more than 4.9V​

consistently on the CPU then you are at liberty to replace BR2 and​

its capacitor.​

Yep,trust the legend -good chance it's the connectors.

Have heard of bridge rectifiers and caps sometimes curing it.Also had one where the dmd was to blame - but ok in another game but would go connectors first

thanks pinheads!

It could hate you,stroke,caress it,say you love it,see if that helps

thanks both, i'll start with the physical, move on to the spiritual after that
