Re: Different (lower) resistor values on PCB?

So might it be a "normal" phenomena or a/some false other elements? If some error, what should I look for in the circuit? Any suggestion?

Re: Different (lower) resistor values on PCB?


One more question: some diodes show the similar phenomena above, which is weird for me. In hand the diode shows polarity if I check with a multimeter (value in case of right polarity and nothing vice versa) BUT if I solder in the multimeter measure minimal value in both polarity direction. Is it acceptable or I have to seek a bad element somewhere in the circuit?...

Re: Different (lower) resistor values on PCB?

Thank you! So if I understand well, the phenomena is normal in both cases, isn't it? If the resistor shows normal values out-of-circuit measures, will work as must after soldering.

Dear Alls,
For sure it id a stupid question, but help me to understand. I am in a Dell 2007WFP revitalizing project - searching reason why not starting. Some resistors needed to replaced is is obvious. When I have soldered some resistors the measured (with multimeter) values were sometimes rather different written on them. I supposed these are wrong units so I desoldered and made a checking measurement and voilá the values is the same is written on. This happens only in case of a few resistors, most have the same values (+/- 10%) are written on it. "strange" SMD resistors =>103...

Re: Dell 2007FPB teardown



Dear Badcaps, Behemote,
Additional burnt problem here: In my 2007WFPb the IC601 blown up (and some other resistors too). The resistors have been identified but the IC601 complete unreadable. Shall I use 2407 schematic as reference or anyone can give me the written code. I would appreciate....

Hi Badcaps, Soon I will as some tech questions lead back to the time.
