Bose Solo Tv Speaker IR board interchangeable?

[RiverCC77]

I have a Bose Solo Tv Speaker which will only work with the remote (designed that way) the IR board is bad. I can’t seem to find one anywhere online. I’ll attach pictures of the one I removed. There’s an IR board on eBay for a Bose Sound dock and I’m wondering if anyone knows if it would possibly work as an interchange? Or could someone point me in the direction of finding the correct IR board?
Part number 347103-00 Thanks!

First off, Bose are absolutely abysmal for service, they won't supply spares or schematics, and it's basically just cheap Chinese gear.

However, there's absolutely sod all on that board - why do you need a new one?, and why do you think it's faulty?.

Assuming the remote isn't working?, then is the remote faulty? (which would be more likely), otherwise the IR receiver IC may have failed, they do occasionally, and we used to keep them in stock for the occasional failure in TV sets.

So EXACTLY what are the symptoms?.

Hello!
The remote is new and when looking at it with my phone camera, I can see IR light when pressing the power button. There is no IR response to the unit and the LED doesn’t light, the unit however has power and plays the tone after being plugged in. When I was researching the IR board I came across a discussion saying they should’ve done a recall on the IR board because of so many failing? It seems to be a common issue with this unit. Thanks!

Do you have an oscilloscope so you could check the output of the IR sensor?.

Did you find a solution to your issue?
I also have the same Bose system and suspect the ir remote module is at fault

IR sensors do very occasionally fail, enough so that we used to keep them in stock where I used to work doing electronic repairs.

I don’t have an oscilloscope but do have a multimeter.
Would this be sufficient?

No, you need a scope to check the waveform (if any) coming out of the IR sensor IC. You can't check that with a multimeter.
