Help me repair mainboard

hardly... Some more moments can be understood from signals description, which can be found in official datasheets for chipset / microprocessors / system bus specifications...

How (at which conditions) and where did you measure that CPU_RST# is at low level (0.22 volt)? Was CPU inserted in the socket?

So I will take a picture and send it to your mail, your comments are right for me. you can email me with your contact no???? thank you very much.

I'm currently fixing MSI G41-P28 mainboard series 7592-52.2
I used OVM test voltage CPU_RST #. when mounted on the CPU socket, check the power voltage CPU_RST # = 0.22v, compare well with the mainboard CPU_RST # = 1.23V voltage. I read on the forums can remove the IC share a com port communication. I did, but not at the moment.

commonly, CPU_RST# has a pull-up resistor connection to +GMCH_VTT, and is connected to corresponding pins of CPU socket on one side and north bridgge on the other. Did you check NB powers are Ok? Give, please, a measured resistance values from CPU_RST (pin "G23" at LGA 775) to ground and to GMCH_VTT output

To VTT_OUT_LEFT.

If CPU not present, then "to VTT_OUT_LEFT".

you may guide me up display up community is not, requires image to understand specify the problem over.

Dr.Rer.Nat писал (-а): precision, which is VTT_OUT_LEFT.
VTT_OUT_LEFT. = 1.23 v. 62R0402 resistor is R137.

Sorry, I do not have a schematic diagram of this mobo, if you have one, please. send it to
