David sorry to hear about this.
Many disreputable sellers on epay especially from China.
Its difficult to get parts, and service th¨¨se.
Easier to find another one that's 100%.
If it's from eBay I would ask the seller for a refund, unless it was slod for parts only.
Finally P6136 and P6137 are different animals, no parts are interchangeable
