I want to try and replace my A10 chip but I don’t feel like getting a new phone. Is there a way to replace it with a higher one?

Can a battery be checked or tested with a Fluke digital volt/ohm meter? If so what terminals can i check this at the USB connector of an itouch. Would the terminal connectors be the same for all generation?

Hello, today I faced with a problem I never had before on an iPhone 6s. At first I was changing the lcd and everything was ok. Then my customer asked for a battery replacement for this phone. After installation of a new original battery phone got stuck on Apple logo. I tried to put back the old battery, but it also gets stuck... I am trying iTunes restore with dfu mode, but it shows me error (9). Does anyone got the same problem? Is there a problem in motherboard?

@bruceallen78599 it's a TCL so no schematics and no help from the company. You said you have no power from the power supply to the LED connectors. This is a new power board or used? Did you also replace the main board? After all it is the main board which tells the power board to turn on the different circuits (simplified).You need to measure the voltages on the power connector where the main board connects too. If you take a couple of good pictures of all the boards separately as well as a pictures showing the complete backside of your TV. That way we can see all the boards and the interconnect cables. Adding images to an existing question

Will it connect wirelessly to my tablet?

Hi @malutkisiw47949,

Might not be a speaker problem.

It could be that there's a problem with the audio output from the PC.

Have you tried using headphones with a 3.5mm stereo audio plug and plugging that into the audio out port of the PC?

Can you try using a different USB power supply (phone charger with USB socket that you can plug the speaker cable into perhaps?) just to prove whether it is the power supply form the PC, or in the speaker that is the problem

If it is determined that it is the PC and not the speakers, then what is the make and model number of the PC or motherboard if a custom build?

Hi @malutkisiw47949

No worries.

Thanks for the images

Here's an image taken from your images where I've highlighted the faulty capacitor you mentioned that looks like it needs to be replaced but maybe also check the others ones behind as well as I couldn't see them clearly.

Also there appears to be a dry solder joint on the solder side of the board that needs to be resoldered so that it makes a good electrical connection.

Once the truck gets hot hot it starts to have misfires in 5 and 7. Misfire typically only happens at idle after coming down from higher rpm. The upstream oxygen sensors are reading 15 for long term fuel trims. This meaning that we are lean in the mixture. I have narrowed it down to possibly dirty injectors, ECU, Dirty intake valve (sealing issue).
