Posted 3578 days ago by Provocator Hi, I have negative polarity on output from transformer (-200 V). So diode D2 is closed and on C13, C10 is no voltage. I Suppose that transformer's winding is reversed. Unfortunately I see no chance to repair it. Any idea? |

Posted 3637 days ago by Provocator Tamara, you have badly soldered DZ4 diode. See: "There is an error at PCB - Zener diode marked DZ4 should be mount in the way shown at schematic." |

Posted 3653 days ago by Provocator *Solved* Backlight was shining if I shorted with wire pin 2(VDD) and 15(+backlight). Then I try connect another display with another expander and it works. I probably damaged expander during assembling. |

Posted 3705 days ago by Provocator Thanks for the part list... What will be maximal current in inductors? I can choose inductor with load limit 0,285 A or 0,56 A. What do you recommend me to buy? |

Posted 3720 days ago by Provocator I have noticed that in the part list is I2C expander for LCD. Also there is note: I2C Expander for LCD (slightly modified, mechanical compatibility only with type shown here) I am not sure what expanders are compatible. For example this set of LCD and expander is OK? http://www.ebay.com/itm/IIC-I2C-TWI-1602-Serial-Blue-Backlight-LCD-Display-For-Arduino-/171068238966?pt=LH_DefaultDomain_0&hash=item27d4762c76 |
