K7000 P538 Chassis blowing voltage regulator (IC4)?!
K7000 P538 older chassis with STR3130 IC4
I capped the chassis and hooked it up to find the vertical size was huge and could not adjust to fit the screen properly. Read a bunch of technical bulletins and threads that pointed to the voltage reg. being the problem. This board has the 3130 IC. So I order a couple from br and installed one. Fired it up and it pop! so I quickly shut it down. I removed the chassis and upon inspection found burn marks at the mounting screws of the 3130 chip. The only change to the board was replacing the 3130 chip with a like chip. Any ideas what the deal is?
I also looked over the rest of the board and nothing is jumping out at me. Checked the bridge diodes and they all read okay. I did use Arctic Silver as the thermal compound, which I use all the time for CPU heatsinks.. Was this a no no?
Pics attached. The original was 04A, replacement was 04C in pic.
