I try to fixed TTX board with TGM3.
Symptoms of no screen output at all were occurring.
Changed some capacitors, in this case one it was broken 6.3V 1500uF as a result.
The broken condenser appeared to be fine on the outside at first glance.
But I measured the capacitor, it has only 2pF.
This is very tricky.
Damage that is not apparent by appearance alone may be lurking.
Please be careful.
If you try change capacitors, recommended use over 150W soldering iron.
That way, the capacitors will be cooperative for me.
They fall off the board by themselves.
Complete repair board, and power on.
But continue the board symptoms.
Fortunately, I have socket485's homebuilt PC, and the board has self diagnose.
Moreover, it talks about the symptoms for me.(!)
TTX's all parts relocation for my PC, and turn on, it said "CPU error".
I recheck the CPU, some pin was burnout and disappearance.
I found a new CPU (Celeron 2.5Ghz SL6ZY) and buy it, and replace it.
Turn on, and Displayed BIOS.
Complete fix.
...But, displayed "CODE 900"
It looks like it will be a long time before it is playable.
