Re: Vizio ld-4655vx

Re: Vizio ld-4655vx
That will probably be a Fairchild FDS4435 (I have used this MOSFET on other boards before.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Hi,
I have a Asus Q540v laptop which has no power. I opened the laptop and found this burnt chip. Unfortunately, the marking on the chip is damaged. Anyone able to identify this chip?

Hello All,
This is my first post here, I have worked in IT all my life however my knowledge when it comes to component level motherboard repair is extremely limited. That being said I have been attempting to learn more in this area. This laptop in question had liquid spilled on it a couple years back. No repair attempt was made at that time.
Upon plugging the laptop in and attempting to power it does not do anything besides show a white status light on the front that blinks on and off continuously. I then proceeded to remove the board from the laptop and inspected further.... -
I have an SSD from a 2012 to early 2013 Macbook pro, the SanDisk model SD5SL2-512G-120SE
Attached is a photo of the burnt chip. I'm assuming it's some sort of voltage regulation chip. The numbers are obscured by the damage.
I am attempting to recover data from this SSD, obviously this chip needs to be replaced before anything can be done.
Is there anything else I should check to verify the health of the NAND?
Thanks if anybody knows what part I'm looking for.... -
Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...
