Blinking Green light on CR but no display on TV

Hi all, first of all would just like to say thanks to everyone on this forum, I have been reading and learning so much from everyone's post and responses.
Having attempted to install a CR on my XB (zephyr mobo ) I have fallen at so many stages but having read everyone's issues I have manged to overcome them one by one but have now hit a brick wall. the story so far:-

  • Read Nand with Jrunner and Nand-x (finally)
  • Compared successfully
  • Soldered CR on mobo (see pics)
  • Flashed the CR first time (go me!)
  • Created ECC
  • Wrote ECC to Nand successfully
  • Disconnected Nand-x
  • Attempted to boot in xell (no display on TV)
  • Attempted to boot normally (no display)
  • Turned off CR and booted (still no display)

I know my soldering isnt 100% perfect but I have re-soldered these now about 6 -7 times

Any advice would be appreciated, let me know if you need any more info from me.

Thanks in advance.

What is the console's CB version?

Bridge the "CAP" pads and see if that makes a difference.

Well your coolrunner soldering is very bad, giving you most likely the non function problems you're having, and i don't know when you took that picture, but the switch is still on the program side, so booting to xell will become difficult.

I think is wise to make a few more pictures of the coolrunner and how everything is connected topside and downside (wire routing etc), and resolder the coolrunners wires. Then try it again.

Btw it's also smart to update jrunner, see the green line on top of jrunner...
