    Need suggestions repairing PSU

    My soldering tip is a bit too big for this job, it took me long time to solder it, I might remove the transistor and hopefuly it works without it there. Also I think the transistor is not same as the old one because it's physicaly much smaller...

    Need suggestions repairing PSU

    I finally recieved the transistor and soldered it in, bad news seems when I measure with multimeter I'm not able to get correct readings... only Black purple gives me good readings: Black Purple: 5.17v on level 20v on multimeter. Black Red on level 2000m: 0019 Black Red on level 20v: -0.02...

    Need suggestions repairing PSU

    thanks that makes sense, Phaedrus suggested me the transistor, he was not 100% sure about it, however I know he knows about psu's so I'm hoping he's correct about the transistor. I have ordered the transistor should have it next week. post17 regarding the transistor...

    Need suggestions repairing PSU

    So on another forum a user suggested me a transistor which seems like he knew was the correct one. Are these correct steps for me now? I have ordered the transistor, I should have it nextweek for soldering :) I want to be sure to have tested as good as I can before installing my PC components...

    Need suggestions repairing PSU

    On another forum a user thinks the LG is label for Toshiba, 2SC2712, according this manual the G stands for DC current gain hFE. Toshiba datasheet In that case I think a BC846 Transistor might be correct? There is 3 transistors on Elfa, difference are 330mW, 250mW powerdissipation, and marking...

    you clearly lack any reading comprehension but anyway thanks for trolling me :p

    Need suggestions repairing PSU

    so on another forum I was told it could be a NPN transistor, still not sure if its PNP or NPN. however Elfa has 26 different NPN transistors and they are all rather cheap: https://www.elfa.se/elfa3~se_sv/elfa/init.do?toc=19098&name=transistorer_med_integrerade_motstand

    Need suggestions repairing PSU

    sadly the transistor says nothing else besides LG, I think it's possible it's that LGE company that makes them, unless it's the actual big LG (smartphones, tv's etc). I actually own two glue guns, one specified 170celsius and one mini low heat glue gun specified 95celsius. I only have glue...

    Need suggestions repairing PSU

    That alibaba link could very well be it, I'll read that link you posted and try to measure with multimeter the "healthy" transistor that is on the PCB bottom in soldered, I think the loose transistor will be difficult to measure with my multimeter. I have a cheap multimeter. I don't live in...

    Need suggestions repairing PSU

    So if I do those measurements without the transistor installed and all shows correctly I have a working PSU(?). Is there anything else I need to consider regarding that transistor. Thanks I know of ELFA, it's a bit long distance from me. So, I spent alot of time trying to solder it in there...

    Need suggestions repairing PSU

    so what happens if I bridge the 3 solder points with a wire? I loose overprotection for PSU? BTW can I try the PSU without that transistor?

    Need suggestions repairing PSU

    so how do I figure out the exact model of that transistor so I can order a new one to solder in, this one must have had it's legs broken I guess, there where no legs to solder.

    Need suggestions repairing PSU

    Thanks, I'll take better pictures and pos in thread, as for that SMD BJT or whatever it is, is there some "trick" I can do to get this PSU going without the black square thing? Is it critical to have that square thing inside the PSU?. I guess I have to plug to wall the PSU and measure to see if...

    Need suggestions repairing PSU

    So I finally inspected the PSU closer and found the problem mostlikely, this tiny black square "memory module" labeled LG had been ripped of the top solder point, it seemed to still be held together by the 2 bottom solder joints (so 2 bottom 1up in total) however when I tried using a tiny...

    Need suggestions repairing PSU

    Those pictures are not mine but from a review (on this same PSU model). According the review the soldering was good and some of it was hand made soldering. I can disassemble the PSU and take pictures ofcourse, btw is it possible to measure with multimeter any of those legs on the daughter...

    Need suggestions repairing PSU

    It was workin fine, after I replaced the fan it did not work, after I put in a new fan I did try with paperclip the PSU and neither the internal or external fans started up. I believe the problem is that tiny daughter board that the fan plug made move about 1cm, I think it could be damage to...

    Need suggestions repairing PSU

    I think need to use screwdriver and screw off the PSU internals to get good look at that tiny PCB, I think the powerplug is attached to the case, obiously the powerplug is to close for me to know if PCB is damaged as there is only a small gap between them. If I succeed reapiring the PSU, what's...

    Need suggestions repairing PSU

    Recently I replaced fan in the PSU, The fan molex pressed the green pcb card and made it move. My suspicion is either soldering got loose on powerplug or a component on that green PCB got damaged. I have a soldering Iron + multimeter, I'm going to disassemble the PSU. Now I need suggestions...

    Can you unlock shaders from ASUS 6950 DCII 2GB?

    if the card breaks to a point of not be able to flash the original bios.

    buying 6950 non-reference

    ah, but having a list would still be helpful, if 400cards unlock out of 1000 then can make a guess that propably 35-45% chance of unlocking. If 50 out of 1000 cards unlock then most like 3-7% chance of unlocking a new card.

    buying 6950 non-reference

    with other words it's similar to unlocking cpu's some unlock shaders other don't. is there a list database of new batches shader unlock rate for 6950?

    buying 6950 non-reference

    Ive read some reviews of Sapphire 6950 Dirt3 2fan modell and Asus 6950 DCUII. Is there a good chance to unlock shaders on these? Seems as both have dual bios but AMD is cutting off the "extra" shaders is my understanding?

    Can you unlock shaders from ASUS 6950 DCII 2GB?

    doesn't unlocking void the warranty? unless able to reflash original bios to the card?
