Re: need to id q86 on ms-6541 ver 1.0
Any chance of saving that?
Looks like something went a rye in the ram and burnt that out. Had that happen on my ECS rs482-m754.

sure.
thats why i asked about the transistor.
easy fix.Comment

Did it go orbital or just sub-orbital??

i got it under a magnifier and got 2sc5001.
btw digikey has it.

Re: need to id q86 on ms-6541 ver 1.0
I've had one of those MBs around here with that same device cooked off in the exact same way, for a couple of years before trying to find out what a "Q86" was. Hmmm? OK, longer than that now . .
Anyway, I was going to build an inexpensive system for a technophobic type, and at the time, an AMD was a better idea, but as anti-tech as he is, I worried he'd be worse than usual if it was not the more heavily advertised "Intel Inside" P4. This MS-6541 had no bids on it at eBay, and I wasn't diligent about the fine print. My bid was the only one.
But the seller had warned about a "bad Q86". I had no idea what that was, and for a dollar, plus about $8 of shipping, I just took my medicine (paid for it whether I wanted it that way or not). Now, the thing showed up when clearing a space to put another surplus item.
For $9, is it really worth my time to try my hand at soldering (well, de-soldering first) on this motherboard? It's not much of an MB, limited mostly to 2.0 and under P4s, as it is . .KiwiComment

go for it. if you let it sit then it is dead for sure, if you try to fix it then there is hope.sigpic

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... -
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... -
This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets...
