Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
That's why I build with Abit and MSI MB's (: -
Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
Better picture:
The caps are OST brand 680µf 4V. All ten caps of this type are bulging and oozing the brown stuff from the vents. The board was purchased from Newegg in November 2004.

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
Asus was one brand that the caps plague didn't hit all that hard........ Its really sad to see this, especially at this point in the game. Shame on Asus.<--- Badcaps.net Founder

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
I received my replacement board today. It's a newer revision of the same model and the affected caps are all a different brand.
I'm glad they corrected their error, but it would've saved me a lot of hassle if they had used good caps from the very beginning...Comment

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
my housemate had the same asus MB, and problem!
my pics look nearly exactly the same, so I won't post them.
it all started about about mid summer early this year (Aussie)
system would occasionally crash, bsod etc.
went through all the usual sypmtoms, eventually saw the
caps leaking. He put up with it by adding extra cooling, but that
was only good for a while, then when the heat came back on this
summer, prob back. so I found a suitable repalcement in farnell
and went onto the job of replacing.
I had forgotton about the stackcool layer on MB (essentially just another
piece of PCB attached at critical points to the MB) but it acts like a
big heatsink, and took about an hour to remove (without damage)
by careful use of desolder wick. I was then able to attack the caps in
the normal manner. Just using the standard technique with the stackcool in
place was not possible (too much heat needed and still not melting solder closest to topside).
The caps I used were SANYO 6SP680M (not stocked by farnell anymore).
The end result was board worked again, and all instablity gone
he can actually now OC the board and stay stable.

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
Thank you for this site!!! MY P5GDC-V looks exactly like that. All of those caps are oozing. The thing is with this board, its hard to see those with the heatsink fan on. I didnt even think to check under there until I saw this thread. The on-board video stopped working about a month ago. I bought this board less than a year ago, where is the best place to try and get a replacement? Straight from ASUS?
This is a really pretty pathetic problem. On such a new motherboard!Comment

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
Here is a picture of my P5GDC-V. These motherboards have a 3 year warranty, so I called the place I bought it from and they are RMA'ing it.
I guess I was lucky the board still worked, except for the onboard video. I could not use the onboard video at a higher res that 800x600, and the picture had bad interference lines running through it. Kind of like an old tv with an antenna. Also, it would randomly reboot when using the onboard video. Switching to external video card worked, but I didnt buy this motherboard to throw away a video card!!!
Purchased December 2004. All 10 caps show signs of bulging or brown gunk. One has it coming out the bottom. I also found a pile of brown stuff sitting on the pci-x connector. The caps appear to be the same brand and type as thatdog's.Attached FilesLast edited by hokieengineer; 11-30-2005, 12:07 PM.Comment

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
thanks for the pic. it is always interesting to see how the new boards are doing. (considering that many people still believe the badcap situation is something from the past)
i am hoping you have the same luck as the previous poster thatdog and get a new board without the ost caps. please let us know what happensComment

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
I've had a P5GDC (but not a P5GDC-V Deluxe) for a couple of months, and I could not see any bad capacitors (they appeared to be ones of my first choice in quality electrolytics). If this is true, some manufacturers are selling deluxe boards at almost the same price, but with some cost-cutting in the quality of the electrolytics.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: ASUS P5GDC-V DELUXE - Very recent board, bad caps
But wait! I see something different about these OST caps. They're less than 1000 uF! But are 4V! Most motherboards don't have such cap values, AFAIK.Originally posted by thatdogBetter picture:

Makes me think that could be the cause. Thus it's possible that Asus didn't use the right cap value! The caps likely are getting overloaded because of the microfarad rating! Also, unlike many of the OST caps, these have a bright blue wrapper! The OST caps on my Asus A7V8X-X next to the processor socket have a dark blue wrapper. And they're probably 3300 uF.Last edited by RJARRRPCGP; 12-12-2005, 06:21 PM.ASRock B550 PG Velocita

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
Only 6800 uF total, and most likely not all together. The 4V rating means that everything (CPU, memory, AGP, etc.) is being regulated off the 3.3V supply. Recapping with 1000 uF, 10V caps would give almost 50% more capacitance in each location, provide better voltage transient capability, and would probably actually reduce peak load on the power supply.Originally posted by RJARRRPCGPComment

> I see something different about these OST caps. They're less than 1000 uF! But are 4V! Most motherboards don't have such cap values, AFAIK.
Normally, the low voltage, low capacitance caps in the CPU/VRM section are Solid-Polymer-Aluminium (SPA) caps, typically from Fujitsu. These are the small yellow caps with a K-vent on many Intel motherboards.
It's possible that Asus cheaped out and went for a less expensive, conventional Al electrolytic from OST, and those can't handle the high ripple currents that the SPAs are designed for. Hence the blow-outs.Comment

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
Maybe it should be it isn't? Newer P4 boards runs CPU regulator always off 12V (that's why the additional power connector with two 12V and two GND wires is there). Maybe the caps shoule be rated 16V?Originally posted by AK0RComment

Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
if the voltage those caps filter exceed 4v you wont care about the caps.
the cpu will be dead long before the caps fail.
they filter cpu vcore.Comment
-
Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
Most probably the caps are located after the VRM's so the input side on the VRM sees 12v but the output only CPU vcore, i.e. around 1,5v... So the 4v caps should be more than enough... A test with a multimeter would be easy enough to verify this..."The one who says it cannot be done should never interrupt the one who is doing it."Comment
-
Re: ASUS P5GDC-V DELUXE - Very recent board, bad caps
Sorry, I was thinking the caps were filtering the input voltage.
Per's right, the caps should be filtering whatever is coming out of the VRMs, for all their various functions. I think linuxguru hit the nail on the head; a total misapplication of required function, trying to save a few cents per board.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi and thanks in advance for any input you might provide!
I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.

Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off.

Good day!
I have a Samson Resolv studio monitor that has no sound output. I've opened it up and found two caps that are bulging on what I believe to be the power supply section of the amplifier board. The board is marked Resolv 65A AMP V1.2. The caps in question are YUSCON, 2200uF, 35V, 85C temp and have markings of RA(P) and are 16mm x 25.5mm tall. I've attached the schematic and the caps in question are C5 and C6. I'm assuming they are low esr caps. I've tested both caps and they test low uF, nowhere near 2200uF.
I'm going to replace the caps and I'll be the first... -
My 3.5 years old monitor (BenQ SW2700pt) started to black out for 1-2 sec every minute or so, it was doing this even with PC disconnected from it. I searched online and read that it's probably aging capacitors and there's a workaround to lower the brightness.
I lowered it from 100 to 65% and it indeed helped, but after a couple of months the issue returned... I continued to lower the brightness, but it helped only for a couple of hours at most, then I needed to lower it further... Turning the monitor off and waiting for it to cool down also helped for a short time, after which it...
