Summary:
We have 4 dead guys: W PP6TT1, E PP9TT15, W PP2TT10, E PP1TT31
and three which did not well in the 7 pattern but they respond to vped changes and see cosmics (WPP9TT30, EPP10TT10, EPP9TT26), where WPP9TT30 has a wide pedestal.

7 Pattern test done:

Rest swapped channels are ok! 

April 8

another 7 pattern test done.

1 tile dead: WPP6TT1 (as used to be)
Bad tiles: WPP9TT30 (wide pedestals), E PP9TT15(not perfect pedestals), E PP10TT10,  EPP9TT26

I used the scope to check if the channels respond to the vped changes and if we can see cosmics
