Acer Nitro 5 AN515 - No power, board repair - ISL88739 chip replacement

Sorin, i am sure you mistaken when you said 100 ohm resistor, but for the other audience which is learning, that was a 10 ohm resistor. 101 should be 100 ohms. Cheers!

25:12 It was me :D 12 days ago we spoke about that in comment... thanks for measuring removed resistor :D

I have the same laptop I5 8300H GTX 1060 - I changed the screen for a 144 hz one and added 16 gb ram, and a 2 TB firecuda ssd/hdd hybrid been working flawlessly for almost 5 years now. I also replaced my SSD for a 1 TB Samsung 980 after updating my stationary :D I've replaced the fans, and thermal paste a due to noise once.

Sir, I pray for your long life and happy family. You are an inspiration to me. Love ❤ from Bangladesh.

I am learning day by day just by watching your videos and I am confident that I can diagnose the same way on some laptop.

[michelk]

Youre the best repair man i ever seen. 👍

You know you're watching a pro when it looks pretty easy, but if you try to do the same you find out it's really hard. I have this same laptop and I enjoy it a lot, I believe Acer did a lot right with this series, that's why it sells a lot, and if it sells a lot you know you will find replacement parts for it.

What a lesson... You are just amazing sorin...

Sorin, you could ask Mouser or any PCB manufacturer if they want some ads in your videos. With the main audience of people interested in electronics, we wouldn't mind this, but will help you with some money to always have good materials and components you need for repairs

I use to think your videos are long and boring but watching this video and gaining all this knowledge on top of the knowledge i have made me feel ungrateful..the way how u tackle this problem is very educational and i sure did learn something...thank u

I admire you! I don't have the tools or your wealth of experience but I can say from a Manufacturing perspective that making a Light Bulb that Lasts Forever makes for a Bad Business Model! I've worked in the Repair Industry and in Manufacturing and there will Always be work for Repair Engineers.
I used to think the contrary and saw the decline of Domestic equipment made to last in favour of replacing them when faulty

Thank you Sorin, had this exact same issue except with an HP that they refused to warranty. Repaired it myself. Talk about annoying. Since they won't honor the warranty might as well roll up my sleeves and do it myself. The next part was Renesas bought Intersil and they won't release the full schematic. I finally found one of the pinouts (not values though) after hours of searching but I already condemned the chip anyways. I'm glad you delved into this fully because I thought I was crazy. I wonder if it's a gaming laptop thing, I'm going to put a cooling pad on it when done just in case... I'm only guessing maybe it is heat from excessive gaming. I always make sure my laptop is elevated for airflow but even then....

Hi. Mr surin. You are a real engineer. Im learning lot of best thing since i found your channel. When i watching your channel you are solder new chip using old nonlead solder remaining on the board. By the my experience that solder not flow very well and need more heat to melt that solder. At this movement im doing i clean old nonleaded solder and apply leaded solder with good flux. It will melt very easily and flow very nicely. Mostly its not make solder bridge. Actually i dont know your point of this step just i share my experience. As a beginner i dont have a ton of experience like you. Do not miss understand about my suggestion. Im still learning from you.

Bravo, te urmaresc de ceva timp, in unele faze cu gura cascata 😁

[predatortheme]

Had a similar issue with the power management chip, replaced it and laptop worked again. Mouser is great for ordering stuff :)

[onumaking]

The channel is so educational, it's a dream come through for me.. God Sorin 👏🙏
