    Hello

    17IPS20 power supply 23254564 I need information on the type of U217 system in the standby inverter on the 1Q001 5083 housing, after the schema analysis it is definitely not SG6742.

    And you can ask for the type of integrated circuit housing?

    or choose the system you want (after writing out the "pins") link

    ps
    Enter where, what pin. it's connected

    e.g. pin.1 mass,
    pin.2 FB,
    pin 3. .. through R (or C) to ground, ...

    Hello
    I am looking for something on the NCP1207.
    The pins look like this:
    1 - OVP
    2 - FB
    3 - CS
    4 - weight
    5 - DRV
    6 - VCC
    7 - not connected
    8 - HV

    And I will ask for pictures - the integrated circuit, the place of installation, the entire board.
    So out of curiosity what is the factory for the invention, because judging by the application, there is a lot of insertion there. The nuances matter.

    Both systems are the same with the standby and main inverter.

    In my opinion, this is some Chinese FAN6300 used in 17IPS20 R6.
    I also suspect that it is 10001 and not 1Q001.

    Compare this application NCP1207 with 42LG5000 LGP42-08H EAY4050530
    - NCP1396A, SG6961, NCP1207

    For replacing FAN6300 with NCP1207A link
    * he may approach NCP1271A

    I confirm 1Q001 in the 17IPS20 power supply as well as in the 17IPS62 power supply to FAN6300. Proven both in one and the other.

    Last-minute correction. FAN6300 in 17IPS20 works correctly, while in 17IPS62 it's not quite right. In the STBY state, the voltage pulses with low frequency and the TV does not always want to turn on. In order for the power supply to work properly, it should be preloaded. I used two parallel connected 470? 2W resistors. This is an ad hoc solution. Probably the layout used is something other than FAN6300.

    Hello

    The power supply of course is already repaired, FAN6300A has been inserted.
