    Re: Chinese supplied IGBTs

    I dont think Utsource will care to much, at best you will have your money refunded. My advice wait for RS/ Mouser/Farnell +Digi-Key to restock from Fairchild

      Re: Chinese supplied IGBTs

      If I get my money back then it's ok. I fixed the tv with original parts from 2 "new" SS boards and I ordered the FGD4536 from a different source. Will see what happens.

        Re: Chinese supplied IGBTs

        I have a parts tester that comes in a kit. It is pretty acurate with most parts. When I got a few different orders of IBGT's that I found out were fake, I tested them and they just read as a capacitor.around 1250pf.

          have you got a link to the parts tester you have been using thanks.

              Cool , will order that! Does it read the IGBT's? ( Will it tell if they are fakes or not ).

                Re: Chinese supplied IGBTs

                It will read as a capacitor between two of the legs.
                If its good it will say something like n. e. mosfet and give a capatiance and a voltage. I think it is the voltage needed to make it switch. It does NOT come with directions on how to build it, but its not too hard. It looks like they make better ones now.

                  Re: Chinese supplied IGBTs

                  Got a reply from UT source saying I need to use them. They say they are 100% original ...

                  Mine all measure 2.7 M Ohm , how do yours measure Flocko/Timmy? Mine are all different batch numbers but I can't remove them with alcohol/aceton.
                  I got a feeling they might be ok but I'm afraid to use them haha.

                    They also told TW and myself the same thing about the fake 30F131s they supplied. I was told to test them. But the only real test is to load them on a working board and see if they work.I sent a batch to Toshiba for them to look at, but they would not get involved as Utsource are a clearing house for unwanted components, they said it would be to hard to trace were they were supplied from, just use them or send them back for a refund,as I have said before you can only test them for switching , measuring resistance or capacitance of these components is not a way to test it

                          Thanks , I must wait for that meter to come in. It might not always be correct but it will help.

                          I ordered FGD453TM from a company in hongkong , they are not on ebay. They provided pictures of the component and they look the real deal..... will wait and see what comes in. Hope they are ok so i can start repairing again.

                          30F132 instead of 30F132 ....that not a option?

                            Re: Chinese supplied IGBTs

                            The tester is thinking it has been presented with a Mosfet not an IGBT this can be seen by the screen showing MOS + G.D.S (gate /drain/ source).being that an IGBT is Mosfet+BJT devise making it a hybrid transistor it is beyond the range of this parts tester.you could build a stand alone IGBT tester, but that again would only test switching (same as using a meter) not under load testing were the fake components let us down.when I have tested any of the fakes they normaly test fine(swithing) as an IGBT should, but will blow under working conditions (load or voltage).

                              hi all fgd igbt is cheaper to buy from rs and most of the igbt you get are refurbished or remarked there is lot of fakes you need to know the supplier well and pay bit more you get the right bits

                                  No no , he means that there are copies out there. Parts that look the same but dont have the same specs ( 30F131/FGD4536 etc ).

                                  I ordered them from HKinventory , got a nice deal. I compared them to the originals and fake ones.

                                  Fake ones --> stamp can be removed with alcohol/aceton.

                                    Digi-key were showing FGD4536 as 1798 in stock , RS also showing stock how many do you want,Microtechservice (proman) said they were refurbished , I asked how do you refurbish a faulty IGBT ? TW has shit loads of them,I am sure he would love to know a way to refurbish them, and so would I, All TO-252 (D-PAK) parts will look the same diodes/ mosfets/IGBTs ,you can only go by trade mark /layout of printing and part number, if these are not as the original parts, then the chances are there fake.

                                      Hi, I'm repairing this Chinese SG2701B01-7 panel. There isn't much information about it. The original part for the panel is a CSOT CS601C regulator. I can't find anything commercial on Aliexpress; there's only the CS601 without the final 'C'. They claim it's a variant. But will it be compatible? Well, my diagnosis on this screen is a video problem; the image is practically black, although there is HDMI communication. The LED light is on (backlight), but there is no VGL, no 3.3V, and no VSS. It seems that this IC is the one controlling these voltages. The monitor worked correctly for a moment and...

                                      This audio chipset has been a pain to deal with, most of the time its impossible to find drivers for chinese laptops that have no name/brand, or generic rebranded laptops.
                                      Huawei also started to use it BUT they no longer host drivers on their website since they want you to force their PC manager app that often refuses to install after bios flashing and apparently the generic drivers around wont work on some intel systems and others wont work on amd systems, the generic ones have worked only once and i think i have had this problem on 30+ laptops so far in the last year.

                                      Just bought a car that has a stereo in, thats bluetooth etc, and powers on fine and all functions seem to work, BUT there is no audio/sound.
                                      I have tried another unit in the car that works fine, so know it definitely a problem with this unit.

                                      Hello, the problem with this TV is it has all the Y and X voltages, but does not produce any image.

                                      It had a TON of cracked solder joints on these boards, fixed all that I could find, but in the last test I forgot to plug in the Y-SUS to control board flat cable, it was left dangling and possibly some pins shorted to the panel metal ground, the X-Main buzzed quietly then blew up in 3 seconds after powering up, annoying.

                                      Two RJH30E2 shorted, they are 360V 35A 1.7VCE IGBTs, the problem is I don't have any 360V IGBTs, only 300V or 600V, would two RJP3065 fit in? It's...
