Title: LM-1 Wideband Repair Post by: eliotroyano on September 26, 2014, 05:45:30 AM Hi friends, I need some help to repair my Innovate LM-1 Wideband Controller. It has been showing Error 3: Pump cell circuit shorted. Checking it circuit seems to me that related ICs will be a TLV2463C and A124 SMD components. See attachments. What do you think friends? Anyone have repair this units? Some advice will be awesome. Thanks, PD: I request manufacturer's help but they point me to buy a new item. :( :( :( :( Title: Re: LM-1 Wideband Repair Post by: flaattire on September 26, 2014, 12:28:21 PM My advice is use a lot of flux and it shouldn't be too hard soldering in replacements to test.

First my idea is to change TLV2463C and A124 components. TLV one is easy, but I can not recognize A124. It is the 6pin SMD IC. Some help will great.Title: Re: LM-1 Wideband Repair Post by: flaattire on October 01, 2014, 02:16:53 PM Googled "A124 6 pin -moc3042" (moc3042 is an unrelated optocoupler that otherwise fills the search)
Found this on another forum, not sure if it's your part though: Pericom PI5A124 Title: Re: LM-1 Wideband Repair Post by: eliotroyano on October 01, 2014, 05:54:21 PM Googled "A124 6 pin -moc3042" (moc3042 is an unrelated optocoupler that otherwise fills the search) Found this on another forum, not sure if it's your part though: Pericom PI5A124 Thanks a lot Flattire, I will check circuit. A doubt in which forum did you found that info? |
