Fraser:
Do you have the original SD Card or is that missing ?
A “Halt” at boot suggests the camera is failing its self test or file integrity check. If the SD card files contain a CRC or other feature that locks it to the particular camera hardware, you will likely have a problem getting it to boot with someone else’s SD Card file set. Some investigation of the firmware file set may be needed to discover whether this is your problem.

You could gain greater insight into what is occurring at camera boot by monitoring the boot log that comes out of the Serial engineering port on the camera. You should see the progress of the boot and where it halts due to a problem.
Make sure that the SD Card is suitable for the role and not a higher capacity than the camera can handle or containing the wrong format.

I do have the SD card but it is not an original SD card. It must be a 2GB blue card made by Delkin but it is a 512MB SD by Sandisk. Therefore I think the card was prepared by previous owner and he didnt succeed. When I look at the contents of Ti45 and TiR3 posted here there are 4 files. One is the splash screen. One is the RBF file which is the Altera FPGA program on the main board (Ti45 and TiR3 are identical and also identical to what I have) and then there are two files DOAS.HEX and DOAS.KEY. I think these files make up the contents of either the MPS430F147 microcontroller or the TMS320VC5510A DSP processor on the main board.
Now I do have a DOAS.HEX file but I do not have DOAS.KEY file. My DOAS.HEX file is also different than the Ti45 and TiR3 posted by other users.
SO I think I might be missing that DOAS.KEY file. I am pretty sure the FPGA file must be the same. The SD card only contains these 4 files (I only have 3)
All the firmware including the bootloader and wince etc... are all stored in the FLASH memories residing on the LogicPD CPU card.
So if anyone has the contents of the Ti55 SD card, can you please contact me?
It might be so that my SD card does indeed have all the files for this model and the non-boot problem is somewhere else but at this point
I need to make sure it is not the SD card content

yes I tried in vain to find any sort of serial debug activity on the 3 pin headers on the board but all those pins are silent. I am 100% the debug info flows if either one pin is pulled low or perhaps a certain character is typed into the RX line (wherever that is) to enter the bootloader
I had a similar experience with another instrument using a LogicPD CPU board that only when you typed in a certain letter quickly at the start then it would stop the boot and take you to the bootloader otherwise there was no activity. However the good thing was that I was able to find the datasheet of that LogicPD CPU boad and trace its UART pins to a header on the board. Here in this camera unfortunately the LogicPD board is very very old and there is no mention of it anywhere let alone its datasheet...so I cannot know where the serial port might be
However, I have confirmed that there is activity going on all SDRAM memories so it is not dead or in reset...so something is happening but ....
EDIT: by the way the main board and the LogicPD CPU card in this unit looks identical to what was posted earlier in this thread from a Ti45 (or was it TiR3?)
anyways, they look exactly the same with same numbers on the parts.

Answering my own question from a while ago.
TiR4 uses a primary cell to retain time and date: CR2477, a thicker version of the typical coin cell.
