Default Bluetooth module rebooting console - fixed

Hi everyone

Thought I would share in case it helps someone else.

About 3mths ago the console screen started to randomly reboot at least once every time I drove. I finally got it to jaguar service who determined it was due to the Bluetooth module causing errors on the MOST ring.

To confirm the service folks took the Bluetooth module out of the loop and bridged the ring with a fibre patch.
this fixed the issue but of course I no longer had Bluetooth. The suggestion was that I get a new module @ cost of $1000AUD+....I therefore started to look for a good secondhand unit...

As an aside I am also inclined to fix old 1970-80ís computers and design/build electronics. Something in me thought ďhey a lot of gear fails due to bad capacitorsĒ I recently fixed the HDMI board in an onkyo amp due to such an issue...hmmm....letís crack open the Bluetooth module and see what we have...

so some one time later after removing the module, which was an interesting but not horrific exercise, I had the module open and on the bench. I could easily see the 4 surface mount capacitors.

So I got spare capacitors from the parts draws and proceeded to carefully replace them. Values are on the top of the cans 100uF (qty2), 470uF (qty1), 330uF (qty1). I used 16V rated parts.

The result is that the Bluetooth module has now worked for over a week and the console does not reboot.

Your mileage may vary.

But hope that it helps someone.

Attached are some images

Original capacitors - 2 large top right and 2 small in middle. The black bar and blue bar is the negative side.

Canít tell from the photo, was there any bulging in the top of the capacitors?
Had to replace bulging caps in some electronic stuff myself recently.

Hi there, no nothing bulging....

I took my "queue" from having done similar repairs on equipment such as
Old Apple MAC - https://www.classic-computers.org.nz...eplacement.htm
Onkyo AMP - https://www.workshopaddict.com/forum...-tx-sr606.html

Both have had the can type surface mount capacitors. To be honest it was a hunch that was quick to check and has paid off.

I have lost track of the other gear that I have got working again by replaced capacitors: old apple II and Sun micro power supplies, AWA Valve Amplifiers, GE Clock Radio, various apple computers, IBM laptops...
