How to "switch off" red LED on LPU5 2

[HIREI]

Hi, all!
BC9, CNI76, 1-LIM system, single (non-duplicated) control system, 2 TMU in LIM:
We had alarm "324 FAULTY TMU BOARD" on one TMU & "62 BUFFER TRANSFER HARDWARE FAULTY",
FTTDI, FTMDI give NOK, well, BLDBI, CNBOE for faulty TMU, second TMU is O.K., but "62 BUFFER TRANSFER HARDWARE FAULTY" remains ?

Well, RFEXI, but "62 BUFFER TRANSFER HARDWARE FAULTY" remains and red LED on LPU5 is lit. What to do to back to normal LPU state, i.e., to go to this state:

"If none of the LEDs are lit, the control system to which the board belongs is in the executing (active) mode in either a single (non duplicated) <...> control system. "

backplanes on those are pcb's older magazines were hardwired.

could be a bent pin in one of the backplane connectors...

Just now we had FAULTY TMU BOARD, INF1=1, 2 again. TMU is installed in new LPB, on the same place as previous one.

Hi,
Now the system is fully up. So, to do it we've done the following:
1. Replaced PSM magazine, then
2. Replaced LSU board.

All other boards, including TMU and power unit - are the same.

Thanks to all !!!
