About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well
Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for
Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer... -
Hello everyone,
I've started to practise more on macbooks air board, I've got a bunch of defective ones, to see if I can gain some more knowledge.
I've been focused on a water damaged board of an 2017 Air.
Someone else already worked on it, the SMC has been reflowed plus some minor reflows around the board.
I've reached a dead end but I improved the state of the board.
Initially it was no power, no green light, no fan spin, stuck at S5 state.
After replacing some components (U7090, Q5500, Q7430, C7432, Q7630, U1950, R6115, R6116,... -
Ok...Quad core prices are down to where I like them. Time to buy a new system. Unfortunately, what this means is that the the two VP6s, which have been serving me well for the last 7 years, will have to be retired.

Anyway....here's the plan:
TRIPP LITE 10 ft. DVI Dual Link TMDS cable Model P560-010 - Retail
$51.96 ($12.99 each)
SAMSUNG 20X DVD±R DVD Burner Black PATA Model SH-202G - OEM

Trying to fix this for a friend who doesn't have the cash to throw at the GEEK squad to get it fixed.
Symptoms:
-Red Standby Light on.
-No response when power button is pressed. No change of any kind. Standby light stays red.
-Got it to turn on once when I was probing for voltages with my Oscope and hitting the power button simultaneously. The problems vanished for a short while and it would turn off and on fine, then it went back to not powering on. Duplicated the same scenario and no dice.
What I know/think:
-Contrary...
