    Hi would anybody have boardview and schematic for Asus f50z 60-nt9mb1300-a02 rev:2.1. I already have the F5Z schematic but its not the correct one. Many thanks.

    I put the coil back in place and now I have the 3.3v and 5v I presume its due to the feedback loop I re soldered PL13 and then then bench supply returned to switching on current limit and going back into the loop. I then removed pq45 and pq44 and the 3.3v returned to pl13. but if I now put 3.3v into either of the +3v (pq45 pin1) or +3v_s5(pq44 pin 4) the the overcurrent kicks in. So basically Im looking for a fault common to both lines. Any help appreciated

    Hi I have issue with 3.3v on Sony motherboad MBX247. I have replace the regulator pu9 (pm6686) and the KBC (slight liquid damage) and lifted the coil PL13 on the 3.3v line as theres also a short farther down on the +3vpcu line . But for the moment I am trying to get 3.3v from pu9 (PM6686) but not getting output. Thisis what I measured so far on the regulator. Pin1 ref 1.8v Pin2 Ton 0v pin3 vin 4.9v pin4 enldo 4.9v pin6 vin 19v pin7 ldo 4.9v pin27 en1 4.9v Any ideas why Im not getting 3.3v out?. When I connect Coil pl13 the bench supply just jumps to 5v then current limit kicks in and it goes to 0v and just keeps cycle. But with the coil lifted on one side the 19v vin stays but no 3.3v output.

    I reflashed bios with the second file in the bios package and now current usage goes to almost 1A but the screen stays white with no external output either. Maybe the screen cable is faulty also. I still need the proper schematic aswell.

    u13 is some kind of regulator but I cannot see the markings on it. If I had the schematic I can do more testing.

    Hi unit was dead initially had 3.3v an 19v in so flashed new chip and replaced faulty bios chip (as it would not read in my programmer). Now get unit powered on but only 1/2 A current drawn and no video. I have 3.3v/5v/1.5/1.05. I have the Tahiti and the Arwen_a1 schematics but both are not correct for this model. U13 looks scorched. The motherboard markings are HPMH-40GAB4200-D430 AND ALSO ON MOBO PCB:41-AB4300-D00G. PWA:40GAB4300-D. Any help is appreciated.

    Thats the model number of the motherboard its used in lots of Sony Models, the name of the schematic is also MXB-223 M971. I have the schematics but the boardview file is hard to find.

    Hi does anybody have a boardview file for this model MXB-223 board?. Many thanks

    That is because its not resolved as Im am waiting on replacement Ic. When an issues is resolved I will mark it so. I cannot seem to find the resolved post. Basically when the laptop is powered up it only draws about 1/4 of an Amp then shuts down immediately. As it shuts down so fast I can only measure the 3.3v which is present all other voltages either do not appear or appear only briefly.The unit then powers off and on in the same loop over and over by itself.

    I see somebody has this problem before but answer is moved to another place and I do not have enough points to buy. This laptop just powers off then on. I have tried different ram and different Cpu still nothing. Any help is greatly appreciated.

    Its not the hard drive I have tried a few different ones. It looks like its a BGA problem
  18. scobie
    Yes Bios flashed, all secondary voltages present/cpu core voltages also present. I also checked all the crystals and the signals from the clock gen all good.The only voltages I found missing are the VDD_LEd led voltage that now seems to intermittently come and go. When I plug the HDD in it does not display now but if I remove the HDD it now displays but if I press anywhere near the Sata hdd connector the screen shows garbled or different lines of color. I suppose its the Gpu needs replacing or reflow/reball then.

    Hi I have an issue with a Samsung R530 motherboard Bremen -UL (100201) ba41-01223a. DDr3 version. Its has no video output external to Led screen. I am using a Bremen-UL DDR2 version which I suspect may not be the same. All relevant voltages seem to be present but I dont want to reflow the gpu until I have more info. Whats the best way to tell if the issue is with the GpU/MCh ? Many thanks

    Hi Im looking for a schematic for A Samsung R530 motherboard Bremen -UL (100201) ba41-01223a. DDR3 I have a Bremen l/Ul schematic but its DDR2 and the one I need is DDR3. Many thanks in advance

    Thanks for the reply buI have made sure its not making bad contact, also the connector and the capacitors behind it are reading ok. I think it might be faulty KBC/SIO so gonna try replace that. Any other feedback welcome as I have not seen this issue before.

    1525 powerboard fixThis is a very common problem on this model, if you are using Original charger then problem is the laptop does not recognize the charger due to the adapter id pin on the small powerboard being open circuit. Here is a picture for you to see and try out I have used this many times.
