Re: Toshiba 32C110U1
It looks like there's a yellow electrolytic peeking out on that inverter board. Did you check those?

Re: SCEPTRE x22wg-Gamer - NO DVI (Factory Repaired Once)
Don't pull the brown chip, that's the processor.
With an ESR meter, you could check the capacitors on the digital board. They do fail sometimes, and can go bad without bulging.Leave a comment:

The power supply in the D530 has problems, but can also be repaired: [url]http://webdevsys.com/d530psuRepairNotes.htm[/url]
The cooling in these systems really does not need to be as bad as it is. One problem is that the inside fan on the power supply is blocked by a bundle of cables. It helps to zip-tie them and get them out of the way as much as possible.Re: HP DC5000 SFF and D530 SFF (ASUS...o be repaired:Leave a comment:

Get some light on it and the camera will be able to autofocus better. If you can set the camera to manual focus, that will help too.Leave a comment:

Re: Samsung 931BW - Takes Ages to Display
There are two other small electrolytic caps visible in those photos. Replace those also, and others elsewhere on the board.Leave a comment:

Re: Samsung Syncmaster 245BW
Those Panasonic EB series are general-purpose, not low ESR. The FC series is available in those values.Leave a comment:

Re: Screen resolution problem...
The hardware should not have any trouble with this. First, try a different video cable, DVI if the computer has a DVI port.
After changing to 1280x1024, do an auto-adjust on the monitor (the "-" button). Some monitors can't get the right settings automatically. On that monitor, the Clock and Clock Phase settings under the Image Control menu might help.Leave a comment:

Re: Samsung Syncmaster 930B - screen going off and on
The one Samsung 931B I've worked on had a very similar power supply. That one had a bad inverter transformer.Leave a comment:

Blown fuse? [url]http://forum.notebookreview.com/dell-inspiron-dell-studio/478489-inspiron-1545-led-screen-no-backlight-5.html[/url]
Post #48 shows a picture, don't know if it's the Inspiron 1545 but should at least be similar.
Don't do what they do there! Bridging a fuse is asking for trouble. But it might help you locate and test the fuse, then people here can help locate a replacement.Re: Dell Inspiron 1545 Dim LED<br />...t-5.html[/url]Leave a comment:

Re: What an analog ESR meter will and won't do
The AC signal is low voltage, my analog one is 0.25V. You can't go too high or it'll start triggering semiconductor junctions. AC, well a 100KHz square wave is pretty easy to generate from a microcontroller. Many have A/D inputs, and libraries for controlling character LCDs are common.
The hard part is doing it well. Input protection is really important on an actual tool. Accuracy, too....Leave a comment:

Re: Samsung 931BF, the infamous "two seconds to black" problem.
Nichicon should have a two-letter series code. The one in the last picture has the UCC/Chemi-con shield logo, and SME is the series. The printing matches some UCC caps I have, so never mind. It's real SME, but the SME series isn't low-ESR.Leave a comment:

Re: Samsung 931BF, the infamous "two seconds to black" problem.
Well, it isn't swollen. But only an ESR meter will really tell if it's still working.
Luxon... not a good brand. Never heard of KSC, might or might not be a problem. It's the low ESR that's important.
The last picture shows a United Chemicon (I think) SME series, which is 85 degree and not low ESR, either. The label looks weird. Counterfeit?
The 22uF is probably a startup cap, it can cause this problem. Use something good, like [URL="http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=P10318-ND"]this[/URL]...Last edited by jsog; 09-11-2011, 11:16 AM.Leave a comment:

Re: Samsung 931BF, the infamous "two seconds to black" problem.
That it stays on once in a while could still be a capacitor problem. Were the replacements low ESR? It could also be a CCFL going bad, which may not be practical to fix.
The 22uF from a stereo would have a different problem. It's probably only rated for 85 degrees C, not 105.Leave a comment:
