iPhone Hardware problems in one thread - Page 110 - GSM-Forum

If you get the above situation, after eliminating the battery problem first, you need to use a multimeter and some related current equipment to detect and determine which area of the motherboard is short-circuited or leaked. Since there are thousands of chips on the motherboard, even if a local area is detected, it is impossible to determine which or which chips are faulty. This requires the rosin detection method. The steps are:

1. Smoke a layer of atomized rosin on the detected short-circuit area of the motherboard.

2. Then power on the motherboard and test it.

3. The flux rosin press on the short-circuited chip will melt immediately, revealing black color.

I just broke the screen of my iPhone 8 badly. Does it make sense to change the screen, or is it a good idea to get a new phone?

To be honest, I think going for a new device might be the better option. Nowadays, iPhones have dropped in prices, and there are some excellent used options available too. For instance, you could consider getting yourself an iPhone 12 https://usedmobiles4u.co.uk/product-...ple/iphone-12/. Websites like usedmobiles4u.co.uk offer a variety of used iPhones at competitive prices. You might find that the cost of purchasing a slightly older model like the iPhone 12 is just a little higher than replacing the screen on your iPhone 8. It could be worth exploring to get a more updated device with better features and performance.
