Address decoding of M1662 failed in one double column of ROC4.
To be decided what to do with this module.
Currently in C* tray.

With CtrlReg=17 the grade of module is B. Still in one double column "noisy" pixels: with hits from other 3 pixels of a cluster.
Stay in C* tray. To come back later.

No hits in ROC14 and ROC15.
Here is an error:
"ERROR: <datapipe.cc/CheckEventValidity:L524> Channel 5 Number of ROCs (1) != Token Chain Length (2)"
To module doctor!

Due to damaged module adapter the first Reception test failed and after MoreWeb analysis graded C.
After second Reception test (with proper connected cable) the grade is A.
To keep grade A instead of C in the MoreWeb summary table I removed the directory of the first Reception:
:~/L1_DATA/M1651_Reception_2020-04-02_16h09m_1585836596 (but the .tar file is still there), run python Controller.py -d (and remove raw with C grade from GlobalFinalResult) and rerun python Controller.py -m M1651

Module has been tested on April 2nd.
Under Molex connector in ROC12 471 dead or noisy pixels.
Grade C.
  165   Tue Mar 31 17:32:47 2020 Andrey StarodumovReception testRT of M1641-M1644
All modules graded A.
  160   Mon Mar 30 17:49:31 2020 Andrey StarodumovReception testRT of M1637-1640
All modules: M1637, M1638, M1639, M1649, are graded A.
  144   Thu Mar 26 17:41:52 2020 Andrey StarodumovReception testRT of M1629-1632
All modules M1629, M1630, M1631 and M1632 graded A
  136   Wed Mar 25 14:44:37 2020 Andrey StarodumovReception testRT of M1627 and M1628
Both modules graded A.
  196   Wed Apr 8 13:40:45 2020 Andrey StarodumovReception testRT of M1625 failed
Silvan substituted TBM on this module.
Now ROC0 does not have hits.
Grade C, goes to "Bad" tray.
  209   Tue Apr 14 15:49:05 2020 Andrey StarodumovReception testRT of M1623, M1657, M1673, M1674
M1623: Grade A, should be B due to 71 bump defects in ROC4
M1657: Grade B, due to 51 dead pixels in ROC12
M1673: Grade A, again 31 dead bumps in ROC12
M1674: Grade A, again 39 dead bumps in ROC12
  197   Wed Apr 8 13:43:15 2020 Andrey StarodumovReception testRT of M1623 failed
M1623: all ROCs are programmable but no readout from ROC8-ROC11.
Visual inspection is OK.
To module doctor.
  133   Wed Mar 25 14:11:35 2020 Andrey StarodumovReception testRT of M1613 and M1614 on Mar 20
Reception test for these modules have been done on Mar20.
Grading A for both modules.
  187   Mon Apr 6 14:42:43 2020 Andrey StarodumovReception testRT of M1575 failed
Silvan has substituted the TBM0 of M1575.
Still no hits in ROC0-ROC3: "NO DATA" "IDLE DATA" warnings
The long cable has been attached.
To module doctor!
  191   Tue Apr 7 14:26:48 2020 Andrey StarodumovReception testRT of M1567 failed
After exchange of TBM1 the results is the same:

WAS:
1567: Grade C, no data from ROCs 8-11, looks like a problem with one TBM1 core

NOW:
-during ThrComp-CalDel scan: WARNING: Detected DESER400 trailer error bits: "IDLE DATA"
- result: INFO: CalDel: 135 134 126 121 158 141 119 133 _ 124 _ 107 _ 126 _ 108 133 91 138 120
ROC8-ROC11 no hits!

This is a module with a broken TBM. Silvan put a new one on top of the broken TBM.
The module is graded A after reception test.
I'm still not sure that wire-bonds of the new TBM is lower than capacitors. I'll try to glue a cap tomorrow
to see whether we could substitute TBMs on another 6 modules with broken TBMs.

Cap has been glued to M1546. No damaged wire-bonds. Vthr-CalDel and PixelAlive are OK.
Module to be (FT) tested tomorrow.

After Silvan removed a cap and re-bonded broken and bent wires M1654 again has been tested.
RT grade is A.
Protection cap to be glued and to be (F)tested.
