  • Atten 938D soldering station question

    Hi everybody!

    I wanna buy Atten 938D soldering station, [url]http://www.ebay.com/itm/ATTEN-SOLDERING-STATION-AT938D-60W-Thermo-control-NEW-/160784734820?pt=LH_DefaultDomain_0&hash=item256f845a64[/url]

    The soldering iron does not have the sensor, only the heater, 2-core. Is there a way to use it with the other iron having 4-core heating elenment with the sensor by making some mods maybe?

    Thank you in advancehttps://Hi everybody!<br /> <br /> ...6f845a64[/url]...

    I found a Chinese site where is a lot of DELTA schematics, [url]http://www.wjel.net[/url], it is a Chinese forum so I MUST be registered there but I don't know Chinese Maybe somebody knows how to get registered there as English-speaking person.

    Westinghouse LCM-20v5

    I have LCD monitor Westinghouse LCM-20v5, inverter/power supply DAC-12M030B Rev1F. If it starts to work from cold condition it waits about 1 sec to show normal image. Then it works fine about half an hour, then it becomes blank. Turn off/turn on – goes to "2 seconds to black" condition.
