Re: Ps4 ADP-240AR power supply
With ADP-240AR check Q5(HS1) STF24N60M2. If it is shorted the problem is solved by changing it. I suspected also R11 which seemed to be shorted but actually it's resistance is near 0 while cold....

Re: Msi p35 neo lga775
Wow, this is probably same board I just recapped: [url]https://www.badcaps.net/forum/showthread.php?t=13123[/url]
It's frustrating that otherwise good equipment is spoiled with a few shitty caps. Reminds me of light bulbs which nowadays won't last too long even they were originally designed to last for hundreds of years: [url]http://www.youtube.com/watch?v=PjjCtBviqrw[/url]Re: Msi p35 neo lga775<br /> <br />...'s frustratingLeave a comment:

Re: MS 7360 P35 Neo F V1
Yes, ESR seems to have raised a bit. But that is situation comparing 1 new cap to 2 old caps. I figured out that ripple needs to be calculated over all installed caps. Then the difference is not really that big.
Four installed Panasonics, total ESR is about 0,0047 ohms compared to 8 OST's which has total ESR of 0,0035 ohms does not sound that bad then. I feel quite safe now.
Also the fact is that OST's hardly lasted for two or three years. Makes me think that whatever is advertised in OST's papers can be considered...Leave a comment:

Re: MS 7360 P35 Neo F V1
Can't tell if I did the math right. Thought that OST's (if they were OST's) might have been those 4V 680uF caps -> with 0.028 ohms impedance and 750mArms ripple.
I can't be sure if caps were OST's as I did not ID originals (was really interested about the voltage and capacitance at that point) and threw them away when I fixed the board some days ago. Though they were OST blue
. If these new caps don't last, no harm done as I can fix my mobo again as this PC happens to be on my daily usage . Fitting FM's was not a problem when I layed...

Re: HP w20 LCD Display Inverter, running out of options.
Update: This monitor has been working now for more than 750 backlight hours withour any problems since it was fixed. Strange that by removing parts you can actually fix something

Re: MS 7360 P35 Neo F V1
So probably my four Panasonic FM's are good enough to replace 8 OST's:
1 Panasonic: 1500 uF - Impedance:0.019 ohm - AC Ripple Current: 2180mA
2 parallel OST's 1360uF - Impedance 0.014 ohms & AC Ripple Current: 1500 mA
OST lifetime 2000 hours, Panasonic 5000 hours....Leave a comment:

Re: MS 7360 P35 Neo F V1
Thanks PCBONEZ, I'm going to pay some attention on those specs in the future. I quess I've been lucky so far as none of the stuff I've fixed have failed yet as far as I know. Or my habit of replacing caps with next bigger voltage value has helped a bit.

Re: MS 7360 P35 Neo F V1
I'm still learning
.
But I have to admit that I have not actually ever checked the datasheets when replacing bulged caps on monitors or mobos. I've been buying only Panasonic FM, FK or FC series caps as replacements because they are sold here as "low esr" -caps. As the failed caps in mobos and monitors seem to be total crap, I see no reason to believe anything their datasheets tell me. I rather just take my chances with expensive caps. This approach has been working quite well so far.Leave a comment:

Re: MS 7360 P35 Neo F V1
Would it have been better to use one 3*1500 & 1* 1000uF caps instead? That would have made it 5500 uF? I'm using low ESR caps.Leave a comment:

Re: MS 7360 P35 Neo F V1
Hi!
I just made "pre" -fix into similar mobo. I wondered how it was still working when I took cooler off. Eight small caps are located under the processor cooler 680uF (4V). As you can see, those caps were bulging from bottom really badly. Could not figure out the maker.
Did not find compatible caps either so I replaced these with 4 * 1500uF (6,3V). I just had to install them lying on the board.
Simple fix as caps are connected parallel, so "upgraded" from 5440 uF to 6000 uF just to be sure :s...Last edited by CapBlown; 04-20-2011, 06:30 AM.Leave a comment:

Re: Acer P193w - blink screen
Try taking a picture of that big 100uF suscon from an angle you see it's top if it's slitghtly bulged. Had similar symptoms with LG after replacing small caps. Eventually it was the big one.Leave a comment:

Re: LG Flatron 19inch
At least one seems to be bulging. I just fixed one 19" Flatron (L1950E) yesterday which did not power up. Changing only the small caps did not help. The huge one was actually the failing part. It was only 68uF 450V and very slightly bulging. I replaced it with 100uF 450V and got the monitor bag alive, so just in case check also the big one....Leave a comment:

Re: LG L1952TQ: White screen, lights on but no image
Thank you Wrog.
I did some googling with array resistors and I guess that this is it 741X083 so I would have 2 of them to replace... but there is something like 0.3 mm to solder each pin in place. Looks pretty much impossible to me. Width of the array is only 1 mm.

Re: LG L1952TQ: White screen, lights on but no image
What are these "AR13 and AR11" parts? Could they be 4 parallel resistors in one chip?
MMC gives 100 ohms when measuring opposite sides. One chip has 2 of opposite sides shorted....Leave a comment:
