Help with finding ThinkPad T460 JTAG Points

[novator2007]

Hello All,

I got a T460 with issue - No picture - Fan on full Speed and no Power LED Light.
Bios already reflashed
All standard voltage is present. CPU on emergeny(?) mode - max 30 c Grad.


By Schematc & BRD View I have found few Debug/Jtag points.
Just not sure which one is correct,
1.There is some(under lack) Test points near CPU - Schematic Page 6
2. J9 26p place for connector - Present: PCH_TMS/TDI/TDO/TCK/RSMRST
3. J8 26p place for Connector - XDP_TMS/TDI/TDO/TCK/RSMRST

I trying to find a correct JTAG Points,already tried "J9 Points" without success(RT809H) 0x00 ID Verification Error(3.3V & others is present on J9)
Read/Write/Erase - all same.

Maybe someome have a expierence with this Model(T460)?

Many Thanks

Problem with reflashing solved(J7 connector+some resistors),but the issue/no picture is still here.
Tried few Bios Dumps and few EC dump - all same.

I think that MEC is dead,no LED and Full speed FAN(also with clear ME)
Any expierence with this EC,its possible to test it without desoldering/replacing?

Many Thanks
