Re: Damaged trace with continuity?

If I understand what you are saying, then the trace isn't the problem, but could be related to the problem, in the sense that a component directly connected to the trace could have been overloaded/damaged?

Does anyone have the schematic for PSU: 6709900017A (YP4201 06.02.15 Rev. 1.3)?

I replaced 4 10V 2200MF capacitors, and now when plugged in, it clicks once while illuminating the green LED on the front of the TV, then immediately clicking again, turning the LED off. I then have to leave the TV unplugged for at least 5-10 mins before I plug it in, in order for it to do it again. If I plug it back in right away, nothing happens...no green LED, no click.

While plugged in, I get the following readings...

At P201[LIST][*]AC pin = 2.25v[*]POW pin = .01v[*]5V...

Did you ever figure this one out?

Re: Damaged trace with continuity?



To clarify my previous response (sorry, I had just taken an Ambien to get to bed), when the probes are touched together, I get 3 Ohms, and get the same when I check any of the traces on the board.

Am I assuming correctly, that the typical resistance of a trace this size on your average board is wayyyyy less than 1 Ohm (wikipedia states that 1 meter of copper wire with 1mm of diameter has 0.02 Ohms of resistance)?

Since my multimeter is unable to measure Ohms at this minuscule level, given the...

Re: Damaged trace with continuity?



EDIT: To clarify, I verified continuity/resistance from those numbered pins to the corresponding pins that would allow me to check that the traces are OK, and they seem to be OK. I also made sure that both ribbons were OK by checking for continuity/resistance at the pins on both sides of the ribbons and they all check out alright....

Just my eyes. I have a loupe I can use to investigate more. Thanks for the recommendation regarding the pictures....

Re: Damaged trace with continuity?



Ha, the same.

And the pins are OK as well....

I apologize if this is in the wrong forum, but this is a board from a car so it didn't seem like it belonged anywhere else...

This is a DDM (Driver Door Module) from my gf's 2002 GMC Envoy, i.e. the board under the driver's arm rest panel that controls the windows, locks, heated seats, etc.

These are notorious for being highly susceptible to damage from moisture, so much so, that they issued a recall (just not for this model year).
