2020-07-09: build night at Bitraf - I took out the processor board and took pictures of it, which I uploaded to the Tandberg TDV 1200 page on Terminals wiki. I also powered on the terminal, and for a brief moment there was some video on the CRT (looked like it has trouble with the vertical deflection, and the lights on the keyboard (Num Lock, Caps Lock) responded when corresponding keys were pressed. Tried a few more times to power it on - most of the times it sounded like the switch mode power supply couldn't start. On the final try (for tonight) the circuit breaker tripped. But now I know it is the power board at least.
2019-10-04: put the pictures of the power board on the Tandberg TDV 1200 page on Terminals wiki.
2019-10-03: took out the power board and took some pictures of it. Didn't find time to measure any capacitors or other components on the board.
2019-09-27: I got a Tandberg TDV 1200 terminal from a friendly swede. Currently the terminal is not working - it needs to be repaired. We checked the power board - mains voltage gets to the board, but it sounds like it is trying to start, fails and reties again all the time. the main board has a battery on it, the battery still have a voltage of 2.7V.
