    Please help me to identify the missing elements on the disc.
    The platform is PWWBE LA-6849P Rev.2.0.

    Toshiba C660D PWWBE LA-6849P Rev.2.0: Identify Missing Elements on Disc (PQ331, PQ332, PQ204) Toshiba C660D PWWBE LA-6849P Rev.2.0: Identify Missing Elements on Disc (PQ331, PQ332, PQ204) Toshiba C660D PWWBE LA-6849P Rev.2.0: Identify Missing Elements on Disc (PQ331, PQ332, PQ204)

    It's about PQ331, PQ332, PQ204.

    Does anyone have a schematic because there may be more surprises?

    In my opinion, PQ331 is the same as PQ351, and PQ332 is the same as PQ352, although it is more "divination" ...

    I'm betting too. The most is about PQ204.

    PQ204 is AO4435L_SO8 but I'm not 100% sure.

    Look at whether joseeph on a hamster does not have such or a related model

    The diagram of this disc is not available at the moment in my knowledge.

    Watching the layout of the tracks also seems to me that it should be a transistor with the P channel, and taking into account the diode in the series (or rather the size of the pads after the disassembled diode) does not have to withstand high currents.

    I would try with AO4435L.

    Upload a macro photo of the vicinity of this transistor.

    Two additional photos of this place from both sides of the board:

    Well, PQ204 is connected to the PQ207 source (on the other side of the board). PQ207 is AO4435L. Considering the above and this fragment of scheme C660 (paltforma LA-7202P)

    Toshiba C660D PWWBE LA-6849P Rev.2.0: Identify Missing Elements on Disc (PQ331, PQ332, PQ204)

    I conclude that PQ204 is AO4409L.

    Summing up, this CD should be:

    PQ331 = SI4128DY (same as PQ351)
    PQ332 = MDS2659 (same as PQ352)
    PQ204 = AO4409L
    PD203 - I'm not sure if it was planted at all.

    Please, verify correctness.

    but it probably was:

    From the picture it appears.

    picture shows this way.

    So PD203 must be for the voltage to appear on the PQ204 which also does not exist.

    I think everything has already been said. Thank you all for your help.

Topic summary

The discussion revolves around identifying missing components PQ331, PQ332, and PQ204 on the Toshiba C660D PWWBE LA-6849P Rev.2.0 motherboard. Users suggest that PQ331 is likely equivalent to PQ351, and PQ332 to PQ352. PQ204 is identified as AO4409L, with some uncertainty regarding its exact specifications. Additional insights indicate that PQ204 connects to PQ207, which is confirmed to be AO4435L. The conversation also touches on the potential absence of component PD203, which may be necessary for voltage supply to PQ204. Users request and share images for better clarity on the components in question.
