This is the board from our bath at home. As you can see from the first picture, when power is run to the board it lights a few random leds before the on button is even pressed. None of the buttons seem to respond to being pressed including the power. I have tested the resistors and they all seem to be fine. When pressed the switches seem to work as far as their tails (if that makes sense). The connector block appears to be clean.
When i bridge different negatives on the switches, they set off led that have nothing to do with the switch in question.
Its almost like something is joining all the different circuits and stopping it from working correctly. I am completely lost.



As i confessed in the title, i am very limited in knowledge. Just looking for any ideas before i get the hammer

Hello,

It looks like the board you got in your hands is only the control and display board.
There must more electronics on the other end of the wiring shown.

You need to know the source of the cables from the connector, do you have a wiring diagram?
It may take a little reverse engineering of the board.
Max.

 

That is the only bit i think i can get to. I will try to follow the wire under the bath but there is very little room.

No wiring diagram i know off. I knew the bath was a bad idea, i blame the wife.

Finding the link to it was hard enough

If a reputable make, usually schematics are available, even if just board to board etc.
Max.

 

I blame the wife...

Yes! Early and often!

 

Definatley not reputable! Its a bath out job to get to the main board. This is as far as i can stretch for a photo. They must have designed this to be impossible to get to!
Do the symptoms i describe sound fixable? I need to weigh up pulling it out and attempting to fix.

 

I would test the board and all it functions first then move on to the main board.. Also it shouldn't hurt to reflow the solder joints just in case..

 

Here are the area's of your controller board that you should look at closely.

Circled in RED are two area's that show potential shorts, like a solder bridge on those two runs
Circled in YELLOW are four areas that may need solder reflow
Circled in BLUE are two areas where the run may be damaged.

The other attachment is just your main box.

Here is a well known troubleshooting procedure.
