Re: Acer AL2416W No Logo, Backlight works, Still no picture.

About the cable: insulation is missing where it's folded 90deg around itself.
So if you get it working be sure to put some electrical tape over it to insulate it from itself and the chassis.

Re: VierwSonic VX922 and VX724 Bad CapXon

Probably this caused the failure.
Try desoldering it: probably the lead has corroded off meaning the poor regulator had to run without any bulk capacitor as best it could!

Re: the gutless, bloated, and fried power supply hall of shame

Nice score, $30 well spent!
Yea the 3.3v on these supplies are usually really silent because they are usually derived by linear regulators from 5v.
So in effect they get filtered twice...

Re: Some serious security bug in INTEL CPUs?? Since Westmere possibly

All I was saying is it's better to hold out a while and see if any issues crop up.
After all what did they say about the first patch, that it was riddled with "reboot issues"?

Of course they...

I'd be careful about any Microcode patches, afaik Intel are still calling them BETA!

Re: the gutless, bloated, and fried power supply hall of shame

dmill89: Just a tip, if your meter can handle somewhat high AC frequencies you can try putting it in AC mode and see what it shows on the 12v rail. (Cheap mans scope ;))

Re: Converting hex to Chinese.

If it picks English obviously your operating system is telling the program that your system language is English.
Otherwise you'd get Chinese!

Everything since Pentium Pro is affected.
It's just Intel being assholes and not making Microcode updates available for CPU's older than 5 years.

Re: Video card Capacitor question

It's to accommodate caps with different lead spacing, 5mm or 7.5mm in this case would be my guess.

Re: Hanns-G Hi221DPB (Hannstar HSG1041) monitor: 2sec2black

That's the job of an X capacitor (safety rated) it must always fail open, never shorted.
Sometimes regular ceramic capacitors are used instead, with horrible failures as a result!

Yes, that one.
If that does not help the primary suspect would be the transformer.

Re: Hanns-G Hi221DPB (Hannstar HSG1041) monitor: 2sec2black

That X capacitor looks very unhappy.
I'd just chance it and replace that along with jerry rigging the 1N4148 diode and see what gives.

Re: Dell XPS8500

It's common for large customers to order custom capacitors, so they are probably not fake.

What the actual fuck, the PCB is completely discolored yet the fan runs at 12v?
Is the efficiency of the PSU below 3% then?
