Chosen Solution

I have an Asus LITEON WN6607AH-AD all in one PC. It is different from the one that I had to choose in the picture to the right, since IFixIt only had an option for something similar. I received it from a neighbor, and it doesn’t power on. I’ve managed to take it apart and do some diagnostics. I’ve tried pretty much everything I could think of, but it won’t boot. I think it might have something to do with a fried motherboard, which is a ET2232I Rev 1.2 board. I’ve looked online for replacement board, but it would be very expensive ($100+). If y’all have any ideas on what it could be or if you’ve had this problem before, then I would greatly appreciate your response. I’ve attached 2 pictures of the motherboard in case that would help.

Here is a list of the things I tried: Installing a ram stick (already has internal memory)Removing unnecessary cables from the motherboardRemoved CMOS batteryTried 2 power cables

Replace motherboard.

  1. TLDR ASUS All-In-One was not booting - just black screen. Possible Fix - New CMOS CR 2032 battery at horrific location.
  2. Background ASUS All-In-One PC Model: ET2321I Booting was flaky for several months. Would halt in BIOS scrolling info, and need function keys pressed to finish booting. After 3 weeks of power off it failed to boot. The screen powered on after power cord was plugged in, but boot button failed - screen stayed dark after many permutations of button press:
  3. Short press
  4. 40 second press
  5. Short and long presses with power cord out, then plugged in.
  6. Testing power Ohmmeter detected about 19V DC - good. Ohmmeter on power button (after case removed) showed 3V DC before press, and 0V after press - seems OK.
  7. Case and motherboard cover removed. https://www.youtube.com/watch?v=pnF7c7tA… A. Two screws under CDROM. Use paper clip to open Plastic in CDROM hard to detach - broke small plastic piece on second detaching.
