Epson 3880 cart blinking in LCD panel

My Epson 3880 has 2 carts blinking in the LCD panel. Reset into the printer several times did not help.
Will replacing the large chip with a spare one help? I only made 6 prints since new installation.

Take the control chip off, seat it back in, tape over the solder points in the back so the control chip is firmer into the cart chip base frame. Then place in the printer. This should work.

Thanks, Walker, it worked on #7 cart, but #9 did not work despite numerous attempts. Replacing the Control chip did solve the problem.
