Dash turns off and on

[Dimplex]

Hi all, been having issue with my 2015 stx-550 No indicators, speedo, fuel, nothing dash is black. randomly comes on an off quickly while driving.

ive tryed : battery terminals* earth wires connecting to motor and chassis* fuses*relays*unplug electrical sockets in bay , clean.. refit.... im stumped.
When the dash goes out the radio goes soft. but if dash flicks back on the radio goes loud again. allso i cannot change gears in my (automatic) when this happends when the dash goes out.

4wd H L range works. works

Am i possibly missing a earth wire i havent cleaned?
i realy dont feel like pulling apart the dash zzzz
Can anyone send me a diagram where the earth wires are? still stumped

Try this: attach a wire directly from the chassis of the stereo to one of the bolts holding the dash in place.

Just slap the top of the dash hard above the instrument cluster. Works for me.

I’m with tony I had same problem when I purchased my d40 so when I changed head unit for stereo ran a new wire from side of it and from the actual unit output earth to a good body earth no more problems

I had the same problem with my d40, turned out to be the battery, wasn't producing enough power (slowly dying), replaced it, hasn't faulted since
