Hi all.
Several months ago, whilst testing a box of old used caps which I had 'assumed' were discharged, the T7 LCR tester I was using was damaged.
When the button was pressed, the display would briefly light up and then go dead.
So, I stuck the T7 in the freezer for ten minutes and 'Bingo!' it came back to life.
Only thing was that after it 'defrosted' at room temperature, the problem returned.
After freeze spraying components one at a time, I managed to pin the problem down to a SOT-8 chip. An STC 15L104W. Which until now, I had just been spraying each time I used the device.
Anyway, I decided to buy a new chip, to fix the problem, however this only makes the problem worse. The device screen merely flashes briefly and that is that!
Replacing the original, bad chip, just takes me back to square one.
My question is, "do these STC 15L104W's need to be programmed or flashed?"
Adding some photos to help see what is inside the tester.
Any suggestions will be greatly appreciated
