Is a replacement circuit board for printhead on Officejet Pro 8600 available?

[George242]

Error message "cartridge problem" . When I acquired printer had same problem, after fiddling with cartridges problem solved by taping exposed ends of ink cartridges. Worked fine till I needed to change out ink cartridges. Now taping ends of cartridges does not help. Yellow is the cartridge with problem. I've cleaned contacts on cartridge, their spring contacts on printhead, the flat contacts on backside if printhead and the spring loaded contacts on the printhead carriage. Still have error message "cartridge problem". Printhead is a little pricey, I'd like to repair circuit board or replace if new board is available.  This printer uses 950 black and 951tri-colors. Any and all thoughts welcomed. Thanks in advance.
