Make sure you didn't bend a pin sliding the tray back in. You think like Robin that the issue is in Vertical board? |

Nothing reported via "I2C diagnotic" in service menu ? We can't check ic2 diagnostic until I resend the board to Stefano. |

We has no solve the latest issue.
It's impossible to set TOP & BOW and vertical centerline.
We tried to swap all boards except controller (no spare).

I resume the post:
We found the problem: the issue of top-bow regulations was caused of a issue of SMPS/G2 Diagnostic board.
We found a blow fusible, swap the board and now the top/bow regulations works fine.
We tried to replace the fusible of the defective board but it blown again.
So with the SMPS/G2 spare board the projector is almost ready to work but remain a little issue: the pulsating light of the blue tube.
We tried to replace tube but the issue not fix.

Hello,
Which fuse ? On SMPS/G2 itself ?
For pulsating blue tube, did you try to swap the video amps (neckboards) ?

Have you tried to :
- Swap RGB input board ?
- Swap RGB driver board ?
- Switch BNC input cables ?
Was the issue present before you swap the SMPS/G2 board ?
Is the issue present with the menus also ?

Also worth trying another convergence board.
Some of them, with revision number lower than 3, had blue oscilation problems. There is a service bulletin here somewhere, it involves changing 8 resistors.
Of course, the best way is to swap with another convergence board, to be sure it is the issue.
