Re: Should I replace bad caps or wait untill failure?
Depends on the cost of failure. For a server replace them at scheduled downtime. For your home computer the cost may be negative because the failure may prompt you to buy new equipment you wanted anyways.Comment

I will just preface all this by saying that I have a fairly technical background but have never attempted SMD electronics diagnostics and repair before, I really like the idea and want to learn.
I have a MacBook Pro late 2016 that died maybe four years ago. Over the course of 30 seconds, it got slower and stuttered, until it froze for a second and died. No click from the trackpad anymore, nothing. I started getting interested in electronics repair and decided to give it a shot, so I opened it, removed the battery (one cell was puffy), took out the motherboard and experimented with...10-15-2025, 01:53 AM -

Hi all, I hope this is the right place to post.
I'm having a problem with a Dell 9310 which is posting 2 orange, 4 white lights on startup (hangs on Dell BIOS logo). The service manual says its a RAM failure.
I've taken the motherboard out and noticed that one of what looks like an SMA 0805 resistor has blown (see photo). The board is an LA-J144P Rev 2.0(A01).
1] Could someone confirm what the component that has blow actually is (and where I could get another from).
2] Whether this component is likely to cause the RAM failure issue, and if replacing... -

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
