Dell XPS 9510 Corrupted BIOS

[alexjthayer]

Hello,

I have a Dell XPS 9510 with board LA-K411P that shows the Dell logo for 10-15 seconds before powering off, the customer may have shut off the device during a BIOS update.

Can anyone assist with repairing the original BIOS file?

The service tag is DVGQZH3.

Thank you!...

Hello, I have a Hp 840 g5 when I was updating the bios. the computer arrived unexpectedly. Now it stays on the loading pass and restarts all at once. it says there (don't turn off the machine until the bios is installed) it's gone there. Here is the bios bin file in question if anyone can help me locate the problem and resolve it thanks....

Hi everyone.
Macbook Air A1466 EMC 3178 (board 820-00165 A) not turning on and no charging light. Completely dead. With no battery connected it would power up and I could hear the chime, but nothing on the screen and then a sudden turn off. Sometimes during the chime. Opened it up and found some liquid damage. The flat that connects both boards has damage in one side (with a missing pin already). The connectors on the boards are fine, though.
Also, there was liquid damage on the included picture area, which are R8111 and C8111. A quick and soft brush on it made the resistor be gone....

Hello
working on a2141 macbook, board number 820-01700 which has no wifi\bt and also no connection with LAN cable.

initial visual inspection the board looks good no visible corrosion or damage.

i found that PP3V3_G3S_X is shorted to ground (around 1.5ohm short)
and also PP3V3_GS3_WLAN i shorted to ground (same ohm reading, around 1.5ohm).

the board is working but no WIFI\BT as i mentioned.

with the usb c cable connected for measurement i noticed U8215 i getting EXTREMELY HOT
so i pulled it out figuring it might be causing the...

Hi,

Sooo - our IT got a pile of old iPads that the sales guys have been mistreating. These are free for grabs if you want to try to get one working. Thought I'd give it a try - if I get at least some life to I can give to my kid to entertain during a car rides.

But the iPad it self - its a 5th gen cellular model. When I initially plug it in it was completely dead. It was not recognized by my Mac nor it started to charge. Disassembled it opened up the battery connector and checked the battery voltage. My multimeter showed 0,7v. Had a spare micro-usb charging board lying...

Hi,

a few weeks ago I saw offers for a MEC1503 on aliexpress. Out of curiosity, I bought one and was a bit surprised when the chip arrived: as you can see in the picture, it was significantly smaller than the original in my ThinkPad. Does this chip really exist in 2 sizes or is it just a fake?

My Sony W905 started to turn itself off an on every few minutes and blinking 8 times red in standby. A few minutes later the tv was completely dead.

Any advice? Thanks!

First of all, I'm sorry for my lack of English.
The part I found the problem in the picture below is no2.
When I check with the bell tester, there is a short circuit. And I checked the bell tester on the no1. The no1 is open on both sides, and the numbers keep increasing.

In my opinion, the capacitor of no2 is the problem, is it correct?[ATTACH=JSON]{"data-align":"none","data-size":"full","title":"KakaoTalk_20240415_190143837.jpg","data-attachmentid":3253096}[/ATTACH]First of all, I'm sorry for my lack...

Hello, I have this HP Spectre 14-ea0023dx (wrong model number in the title) laptop with an issue. When you close the lid, the screen goes off. Then, when you open the lid the screen remains dark while the computer is still running.

I suspect the issue is with the lid sensor which I am assuming is a small magnet located in the lower part behind the screen bezel.

Could someone, please confirm this? Thanks.

[Antonynl]

I have a tantalum capacitors with indicators EB 21 that measures only 22pF. See attached picture.

Since this is a windmeter that is normally in a very high mast I would like to get the correct replacement capacitor.

Is there somebody that can tell me what the capacitance and voltage of this capacitor are?

I don't feel confident that I can figure this out myself after searching around

Cheers!!

Hi,
I'm looking at the power source module of my Panasonic plasma TV TX-P42ST50. The TV goes into suspended state almost immediately and keeps flashing 6 times.
That zener diode is marked on the board with the diode sign (D204), that much I know. It seems to be open completely in both directions and its legs seem dark, as if it suffered some heat.
I'm having trouble finding a replacement. Does 21 stand for 21V?
The only other clue I have it is connected across 2 of the legs of a transformer (primary side).
Any idea how to find a replacement?
Thanks

The monitor is old yes but occasionally used (perhaps about 1 ~2 hours usage per day on average)
one time i turned the pc on and noticed this issue
what could it be?
nothing wrong is seen when it is off, also the issue is not there on a green screen!
when watching movies it is hard to detect unless in black screen/large shadows
please check the images, thanks...

Hello, working on a laptop (MSI GS75 9SG-242US, Core i7-9750H, 2080 Max Q) and after replacing the screen and forgetting to disconnect the battery prior, I have no visible indications of power anywhere. It was working perfectly fine prior to the screen removal and replacement. Checked the motherboard PCB visually near the LCD connectors and didn't really see any indications of damaged surface mounted components but haven't looked under a microscope yet.

Hi,

I've been troubleshooting a Dell U2518 that produces no picture yet the backlight is turned on, the PSU produces 19v, It is detected over HDM and its firmware could be upgraded over USB. So to me the controller board and PSU seems ([I]somewhat[/I]) functional.

There is however a ticking noise from the T-Con board to the left side of the RT6811 chip when power on ([I]not when off[/I]). Also the RT6811 chip gets quite hot ([I]cannot be touched for long[/I]) otherwise there is no physical sign of damage and everything around the board is neatly covered with plastics...

Not a pattern, but inconsistent. I found a faulty mosfet on the power input which I replaced. Problem I have is that it does not start up without a battery unless I use a 18.5v charger. It does however start with the 19.5v with the battery installed, but the battery charge voltage is 2.58v. The required charger for this unit is a 19.5v of which I have tried several. The battery is bad and have ordered...

Good morning.
I have a problem with my LG Smart 43UF640V TV. It starts, the backlight comes on but nothing is displayed on the screen and there is no sound.
I thought it was a TCon problem and ran various tests. If I disconnect one or the other of the cables from the tcon to the panel then the screen is white on the side where the cable is disconnected and black on the other side. If the two cables are disconnected the screen is completely black.
In the 4 configurations I measure exactly the same voltages on the tcon card (model V15 43UHD TM120 Ver0.4) :

The tv will turn itself off after a minute or so automatically. I'm somewhat confused if this is either a eeprom problem or a bad led strip problem. The power supply makes a pretty noticeable humming sound when it's turned on leading me to believe one of the leds are shorted but idk honestly. Any of you guys have any help for me?

Hi all,
I'm trying to fix this NUC, whose sata power cable was somehow shorted (not yet clear).
Standby light comes on when dc jack is inserted, but when power button is pressed this component becomes very hot and nothing more happens.
It's located near the corner of the motherboard close to the ram socket and behind the power button.
Close to it there's an ITE it8566vg (unknown) and a load switch DML3009LDC.

So what is this JWFN 1rD9B ?

I'm repairing an Acer AL1916 monitor PSU at the moment. The 400v high voltage smoothing capacitor C114 is measuring completely O/C. The case of U101 has blown apart. Fuse F101 has blown. ZD121 reads 6 Ohms in both directions & ZD120 reads 99 Ohms in both directions. While looking at the data sheet of U101 (DM0565R), I noticed that the absolute maximum voltage for Vcc is 20v. However, the zener diode across the Vcc pin to GND is a 1N4748A (22v).

Now, whether that zener is used to constantly regulate the voltage, or whether its's used to protect the Vcc voltage from rising too high,...

My sister purchased an M2 MacBook Air a year and a half ago. While she was using it a week ago, it randomly shut off and no longer powers on. There are no signs of life and not even the MagSafe indicator LED lights up.

eBay replacements run about £367 with the Touch ID sensor included.
