Re: Apple iPad 10.2 (2019) - no power
Hi.
1) Do you have test tools ?
2) Is this model with the Apple Lightning connector or USB C connector for charging of the model ?
3) You will need to review the current draw and voltage from the charging port connector. Based on the activity of the current draw, often it is possible to determine the condition of the tablet.
4) What is the history of the tablet ? Was working and then just stopped working ?
5) If you apply the power adapter -> do you see the charging graphic ? Any graphics on the LCD at all ? Any boot chime when the adapter is connected?
6) Can you connect the unit to a Windows PC and does Windows state that a USB product was attached ? Test with iTunes & USB cable.
Try a hard reset by holding down the recommended combination of keys to force a reboot. -

Install iTunes on Windows.
Then connect and see if iTunes can detect this iPad.
Test with other cables. Inspect the lightning connector for damage / debris.
It is common to have this dock flex cable get damaged from physical abuse to 3rd party chargers that are not to Apple's MFI specs.
Tools like tristar breakout board / testers will help.
Tester can quickly determine if the tristar IC needs to be replaced. Do review the online methods to force a cold reset.
Are you comfortable to remove the display? They are very delicate and should be removed with great care and proper tools. The spudger cannot, cannot go in too deep else the display will be damaged. If any doubts, call around your local markets for experienced repair shops.
There is also Ben in Germany. Check his videos on youtube. He is the one with the man bun on his head and tattoos.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 all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

Hello.
Working on an Apple iPad Pro 3rd Generation 12.9" that has a weird issue. When the display is NOT connected, the iPad will charge and power on normally. I know it's on because I can hear notification sounds and the charging notification sound.
If I connect a brand new display to the logic board, the iPad will not turn on at all. When I connect the iPad to an 18W wall charger and a USB-C ammeter, I can see that the iPad is attempting to charge, but constantly "resets" after just a moment or two.
For example, when I connect the iPad to... -

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!
A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...
