So my buddy has this card and might ship it out to me to see if I can fix it. Just need a second opinion. Does it look like the two caps on the left are blown?

Re: Sapphire HD4850
pretty obvious they're blown.
be warned though that they might have popped from one of those stupid "bake your gfx card to fix it" attempts.
if that's the case there's only one destination: trashcan

Re: Sapphire HD4850
those look like kzg.they need no help to blow up in high temp areas.replacement may fix it.those are on +12.470@16
could also have died from eating ripple from a bad psu.Comment

Hi folks,
I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown... -
HP Modelnumber: 14-dh0061nb
This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
All these 3 batteries are charging... -
Hey everyone,
I'm a novice trying to repair my laptop. The LCD screen has an image, but no LED backlight for the image. It also produces an image when connected to an external monitor.
I have found what I believe to be a blown inductor labeled "L4502" and "120 Ohm" in the schematics (zoomed in image, blue arrow to blown component). I have included an image of the general area of the mobo and an excerpt from the schematics as well.
I am having trouble selecting a replacement component, which I believe to be a 120 Ohm ferrite bead, from the components... -
I'm looking at a vented C513 in a Marantz SR5400 (photo included), in the FR section on page 24 in the service manual (https://audiocircuit.dk/downloads/ma...400-avr-sm.pdf).
R533 right below it in the photo is charred, but measures the correct value.
1. I'm not familiar with amplifier circuits (at all — don't know the difference between classes, etc.) so I was wondering what problems would manifest from a supposedly non-operational C513? I didn't hear anything odd when testing the output channel with a speaker. Is there a simple test that can be done...10-21-2025, 09:02 AM -
Hey everyone,
I just went ahead and unscrewed a faulty GTX 980 TI from Gigabyte. What I found beneath the cooler was, as it seems, a common issue of that card. Two blown fuses on the bottom right corner of the card next to a MOSFET.
Now my question would be if there is any schematics of that card available to figure out which are the blown components so I can try and replace them together with the mosfet if needed.
Find some pictures of the actual GPU together with a picture of how it should look like.
I also wonder whther it might be a problem that there...
