![]() Here's the circuit mate, not the best quality I'm afraid. Pin 7 has no connection but I don't really understand your question either.

![]() BN44-00060A Samsung Inverter board.
Pin 7 on that inverter board is not used on that inverter board as shown in the schematic.. That inverter board only need to have GND, DC IN, BRT (DIMMING CONTROL, 0 ~ 5V, 5V = Max lamp brightness)), and BL-ON/OFF (Backlights ON/OFF control, it is active high signal, <1V = Backlights OFF, >2.5V = Backlights ON). So what is it not doing? Do you have all the required Voltage and the two control signals?

![]() "All voltage good" so what are they, report them then.
You just need to do more in-depth troubleshooting that inverter board. That board is made by Samsung so it does nit matter if it is also used in the Dell monitor, the LCD panel is probably made by Samsung. You still do not tell us what it is not doing right, it hard to help when you do not provide the details of the failure, we do not have the board or the monitor in front of us to look at, but you do so need to provide more information if you want the help from the forum. The backlights flash on for second and go black? BTW, Dell does not really made the monitors, the monitors are made other companies per Dell requirement. BTW, you should stick to just one thread: https://www.badcaps.net/forum/showth...019#post880019 Last edited by budm; 02-07-2019 at 09:34 PM.. |
