Re: Socket 775 pin repair

If you can get the pin standing proud (enough), then you can cut a strip of clear plastic about an inch long from a produce container and then kinda slot one edge of it along the pins and gently comb...

Re: No Picture or Audio on Insignia NS-LCD26A

Well, little progress to report, just note to self :

Amazon showed up with 20 35v470uF Nichicon caps for 8 bucks, so got enough to go back and remove the 25v rated ones I tried (didn't help)

Re: No Picture or Audio on Insignia NS-LCD26A

Hi,

I got one of these from a neighbor to repair and it looks like the first one in the thread that actually has bulged caps, 5 on the mainboard and 2 on the PSU board (see attached).

On both...

Re: Say you got a free PSU from outside... and it was raining

That's interesting about the replacement of caps taking care of an intermittent memory problem, another clue to add to my collection. I almost always learn something new reading your posts 8-)

Re: Thoughts on this ESR meter

Sorry, I meant a good quality like Kester 44 60/40 rosin core, it just usually seems to work ok and excess flux is easily removed 8-). Plus the smoke from it gives me a decent buzz (jk). Thanks!

Re: Thoughts on this ESR meter

If I couldn't see the difference I guess I'd be happy. How 'bout a couple details on the 'good stuff' - how well does it perform and how does the cost compare to, say, 60/40 ?

Re: Thoughts on this ESR meter

I'd recomend one of those 'AY-AT' kits, if you don't mind a bit of soldering.

That way you don't get something with that crappy lead-free solder and suspect looking solder joints all over the...

Re: Bad Power & Effects Upon PSUs

Now I'm kinda wondering, would a ups maintain a correct output if it happens to be plugged into a 120vac line that has a floating-nuetral problem, or would its operation be somewhat flaky too - guess...

Re: Bad Power & Effects Upon PSUs

Maybe a poor incoming neutral connection, not good for things hooked to it, especially electronics. If you can monitor the voltage both during the flickering and when not you might gather some more...

Re: ESR meter upgrades

I'd only used 100nF before on the 2 previous testers I had and never had a problem with calibrating, thanks for the info - I'll just twist a couple together and try it with 200nF.

What's "AY-AT"? ...

Re: High Voltage Probes

Re: Rework Station Pump - Can They Be Repaired ?
