Re: HP w1907 monitor
So,
I test it again with a Fluke 787 and get the same reading
I also check the two double diode with the meter and it seems alright, i didn't put the power on with the 5v and 12v, still need to find another power supply. I read on the common pin on the D810 8.40Vdc. On the common pin of D809, 27 - 30 Vdc.
I replace the set of cap of 470uf(3) and the 1000uf(3) but i still get the same result.
All my measure are read when there is notrhing connect on the power supply .
When i connect everything...Leave a comment:

Re: HP w1907 monitor
I actually dont have any new 3v battery cause I put the last one in the meter and it test 2.622Vdc
For the brand new 1.5 battery I got 1.56Vdc
I dont have any zero adjustement on this meter ( it is a Klein Tools MM200) but I have a Fluke at work, I don't remember de model but sur certainly be better. I will test my 5.1vDC with it tomorrow after work.Leave a comment:

I test the fuse F801, it was ok
I test the 5.1V that goes on the Logic board ; when the logic board is plugged I read 1.6 to 2.3 VDC and...Last edited by d_p_c_l_2; 01-21-2014, 02:18 PM. -
