GA-8IPE1000-G Maintenance logs
Plate image is as follows:
Found bus-powered tube visual yellow, first of all replace the
After the replacement play value, there is no short-circuit. Plug in the power trigger. Found to be not triggered. So check triggering conditions of work, found IO damage. Replacement. 【Working conditions on the trigger in the previous day
Chi has written, then this omission】
Chi has written, then this omission】
After the replacement power boot, the measured voltage reset are normal. U do not run code on the client that they have with 【U】 of P42.8
So change our CD 2.53, U ran after the normal code, to fix this board. Do not have time to test because testing is not a good CPU. Written directly on the CPU there is a problem to replace.
Client could go back and put on the same CPU or not, point does not shine. Brought rework. First of all, we can light up the 2.53U. U-he is not, no way to test him to find plate U.
OK, no problem. Depressed in the ~ ~ I U-frequency 533 of his 800. To be sure the problem is with the frequency of this. Determine the customer before the repair is to use this U

This fault has not maintenance experience. No idea do not know where to start. So the first step brush procedures remain the same. The IO replaced doubt there is anything wrong, and back, still clapping. Not recruited. Internet search data, which saw the base has been said that possible solutions for power management chips. So to prepare for. See the power management chip to have a IT8206R chips. Not familiar with this chip, so to search a bit. Also could not find this chip data. Base found inside this chip is to control the overclocking use. Do not know good or bad
Thus, at a material board to find, to find a board with this chip. OK running code to put on a normal light crashed. This board completely repaired.
The board detailed model of this chip are: IT8206R (BXL) I substitution using a IT8206R (CXL)
