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.

by monitronI am working on a HP Pavilion 27-d0010nd that has dark screen. It appears that the backlight is not working.
Now i discovered that the backlight circuit is on the scalar board and has a burnt mosfet. (caused by a ceramic capacitor short).
If anybody can help me identify the partnumber it would be a very great help.
The board number is:
L76838-001
L99794-001
BigBen Scalar board.

by Super360Hi as you can see from title, I have a samsung tv here that will show the smart tv logo and then no picture after that even hitting input or menu on remote and shows nothing but the backlight still appears to be on. 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? I have a good multi meter and can take pictures of whatever...4 Photos04-13-2024, 10:05 PM

by EazyBoneGot this massive TV and tested they backlights and they were out. Took it all apart and replaced them. Put it back together and boom they work! I then run it for many hours and all still working. I then needed to factory reset to pass on to next person and...
I factory reset and it shows Hisense logo fully lit up, then Google logo for a couple of seconds and forces shut off. Now that's all the TV does. Hisense, Google logo force shutoff. How is this possible.. anyone have some experience or advice for this. All I can think is somehow I got a software corruption which is ridiculous...Yesterday, 07:31 AM -
by Ross KohlerHi,
I'm learning about motherboard repair and I believe I've traced the issue down for the South Bridge on the particular motherboard I'm working on. My path of concluding that:
- There's no sign of any attempt to power on when pushing the power button.
- No PSON signal is reaching the 24-pin ATX connector.
- The Super IO chip is receiving the PS_SWITCH signal from the power button and is relaying this signal back to the South Bridge.
- The Super IO is not receiving the S_SLPS#_R signal back from the South Bridge
- If I pull the Super IO S_SLPS#_R pin...Today, 09:36 AM -
