Canicon 1000uf10V looks bulging. I will replace. The PSU is still performing fine though.

Re: Tmp-ans Lc B350atx
those are junk when new.
they tend to trash mobo's when they die .
here is the cure.

came with a cheap case. i guess i wont be repairing it then. many thanks for the advice.those are junk when new.

Re: Tmp-ans Lc B350atx
i didnt even say that. but yes i dont recommend for beginners to try to recap an in-warranty board before the caps start failing. especially something proprietary like a G4. leave that to the pros. out of warranty who cares if the job is messed up, the board was useless anyway.congrats on getting quoted in the cNet article that pauloncall posted about
anyway the more press on the badcap issue the better until someone starts doing something about it.Last edited by willawake; 11-10-2005, 03:43 PM.Comment

Re: Tmp-ans Lc B350atx
I save dead crap PSUs - as component source for other PSU repairs
However, if it works, replace the bad cap (and better also other Canicons too, if any). I see an optocoupler there, so at least it should not burn everything while turned off.Comment

Re: Tmp-ans Lc B350atx
The bulging capacitor is used in the +5V standby rail (If this rail fails, you can't start your computer!
)
Are there any Gincon capacitors in it? (You should find two of them)
The chip is marked "2003", as shown in the pictures - most likely to be a poor quality one. Some quality power supplies from big manufacturers have their own chips in them.
My LC-B400ATX supply was almost identical to these pictures. I'm glad I scrapped it before it damaged my system!
My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment

Re: Tmp-ans Lc B350atx
That is a 350W P/S?! I'd be afraid to use it for more than 250W. Those heatsinks and that power transformer are going to get really hot at 350W. I'd love to know what the ratings are of the +5V and +3.3V O/P rectifers. If the part numbers look something like MBR4060DT, the "40" means its rated for 40A, and the "60" means the peak inverse voltage is 60V.

Re: Tmp-ans Lc B350atx
Very similar circuits of this unit can be found on http://narod.yandex.ru/100.xhtml?ele...Y-B200-ATX.zip and http://www.eserviceinfo.com/download.../L&C_400W.html
I can also see electrolytics with an unknown manufacturer's logo in the attached picture.
As with my unit, the electrolytics (as well as the output rectifiers and the heatsink) were a bit under-rated.

Re: Tmp-ans Lc B350atx
Commonly every PSU model number starting in "LC" means that it's an crappy L&C power supply. Those caps with a logo of a planet in L&C power supplies are generic caps.Last edited by Newbie2; 11-11-2005, 07:41 AM.My gaming PC:

Re: Tmp-ans Lc B350atx
na064,
That looks to be an very obsolete Samsung part - TO-220, 600V, 2A, 5 Ohm, N-channel. SAmsung MOSFETs were acquired some time ago by Fairchild. This looks like a decent replacement. It's same package and voltage, 3A, 3.4 Ohm; it's probably faster, with a lower gate charge (easier to drive) than the original.PeteS in CA

Fixed a 10yo HP inkjet with a bulging cap on the digital computer power rails (1 to 5V). Unstable voltages causing these inkjets to not boot properly or crash quickly. Seems like more and more of these are showing up nearing the 10 year mark. Board design seem to look similar for many of these printers.

Would you consider a slightly bulging capacitor defective if it measures perfectly and it is brand-new? To be honest, they are all equally like this: vent is not totally flat but they have very low E.S.R. and VLOSS is negligible.
So, everything seems perfect apart from the vent looking a bit "strange". They are genuine capacitors, BTW.
The bad thing is that they are 400V capacitors so testing them just to check how much they last would mean using them on the primary of a power supply, which means the risk of damaging the whole circuit.
What do you... -
I have been using a Denon AVR-X2000 receiver in my living room for several years now, works perfectly, am very pleased with it. Recently I acquired another one, advertised as defective with flashing red led a few seconds after switching on. Picked it up to try repair and use in hobby room. After switching on, the on/off indicator led indeed initially flashes green for about 2 seconds, during which the display is visible, and then starts flashing red (at 2Hz) with a switched off display.
I'm afraid the service manual is too large to upload here (55Mb), it can be found at https:/... -
Hi guys.
I purchased this tablet in used condition from a guy claiming nothing wrong is with it.
While I was cleaning the tablet I noticed this (pics) at the top edge of the tablet.It is barely visible,maybe crack is like 1mm wide or so, and I can see probably yellow glue stains.
Now I read about all nasty stuff about battery bulging and causing screen to separate on Surface Pro 4.
Is that even in my case?
Or someone replaced the screen,and didn't use a proper glue.
Gosh,it just made me depressed and worried even more,cuz I'm perfectionist (OCD).

Thanks for any help here!
I'm trying to narrow down which board may be the culprit for my non-functioning TV.
The symptoms:
I was watching (actually playing Elden Ring on) my VizioM70-C3 when half the screen went snowy (sort of a digital snow). I shut down and restarted and the screen was blank.
The indicator LED light in the bottom corner turns on and the audio fiber optic light in the back lights up but no screen.
I tried the "flashlight test" but am not seeing any images on the dark screen.
The internet is telling me that the caps go bad...
