Re: How To Stop CRT Flicker
My preferred method of stopping the flicker by throwing it out the closest window. Works every time, guaranteed.

Re: Need help choosing very quiet case fan
Fan arrived today and I just installed it. Absolutely amazing how quiet it is. Exactly what I was looking for. I think I'll be looking for a Noctua CPU fan now as well. Thanks again!Leave a comment:

Re: Need help choosing very quiet case fan
I just ordered on from the official Noctua store on Amazon. Supposed to be here Monday. Thank you....Leave a comment:

Need help choosing very quiet case fan
My PC case fan started squealing about a year ago, so I unplugged it and just left the case open. Now, after the recent exploding polymer cap, I'm thinking that passive cooling may not be good long term. The dimensions are about 92mm square. Bolt holes are about 114mm apart diagonally. The plug for it is 3 wires and it's for an ATX case. I don't really care what it costs, I just want it as close to silent as possible. Trying to Google this and I get a ton of ads which are probably misleading. I'd rather go with something someone else personal experience with. -
Re: Surface mount capacitor on my desktop just exploded.
The temp virtually anywhere on the board is about 120°F. Directly under the CPU it's about 144°F. I don't actually have a rear case fan running either, but I keep the side panel off. That may be a contributing factor. The bearings began squealing about a year ago and I unplugged it and left the side off. Kind of forgot about it until just now. Can you or anyone else recommend a 92mm fan (bolt pattern is about 115mm diagonally). It has 3 wires. I don't care about cost, I just want it silent....Leave a comment:

Re: Surface mount capacitor on my desktop just exploded.
If I can get another year out of it I'll probably just replace it. I think since it's working, I'll just order the 4 polymers which went bad so I'll have them if the ones I used fail....Leave a comment:

Re: Surface mount capacitor on my desktop just exploded.
Thank you. The machine is probably 10 years old. If I recall correct, the old HD had 46,000 hours on it. That was replaced a couple years ago with an SSD. It's a Digital Cafe IC780M-A v2.0 motherboard with an AMD Phenom 9850 Black Edition CPU. I bought it non-working for $100 a few years ago from a friend who garbage picked it. Replaced a couple bad caps in the PSU and that was fine for another two years, then I replaced it with a Corsair RM850X just because I got tired of it sounding like a jet engine in my...Leave a comment:

Re: Surface mount capacitor on my desktop just exploded.
Probably a good thing I decided to change the other three which were parallel with the one that blew up. The worst was over 40 ohms esr. The other two were 10 and 6 ohms. Capacitance were around 190uf. I didn't have any 270uf caps, so I used two 220uf and two 330uf. I figured since they were all parallel, it should work if I just got the total capacitance close to what it originally was. I'll order caps from Digikey for the entire board later in the week. For now, I just need it to work, and so far it is....Leave a comment:

I'm not sure who jumped higher, me or the cat, but it was loud as hell. I guess it's time to recap it.
Edit: It's through hole not surface mount....Last edited by lookimback; 01-20-2021, 12:24 AM. -
Re: Replacing failed photo resistor. How to determine value?
I'm thinking about doing that. I still have to run the circuit to where I need it, and I may not get to that for a couple weeks anyway. Pretty cool that I'm fixing this for about 4 cents....Leave a comment:

Re: Replacing failed photo resistor. How to determine value?
I'm 100% certain it's the photo-resistor. I've tested it out of circuit and it barely changes between light and dark. Also, I've simulated it in circuit with a resistor and that makes the light work again. I just ordered 20 GL5528s for 82 cents from AliExpress. I guess it will be about a month before I have them....Leave a comment:

Re: Replacing failed photo resistor. How to determine value?
I've been playing around with different resistances and it seems that somewhere around 33k is the tripping point. Anything above that will make it turn on.Leave a comment:

It's one of those chip under blob things, so I don't have any way of knowing. The trimmer on the board is for range. Where am I measuring R?...Last edited by lookimback; 04-10-2019, 01:11 AM.Leave a comment:

Re: Repair side cutter
I replaced these and within a week I blew up the new pair. I needed to cut the end off a cord for a project, and accidentally cut the wrong cord. The one I cut was plugged in. Oops. Was going to upload a picture, but I can't find them. Anyway, you just gave me an idea....Leave a comment:

Replacing failed photo resistor. How to determine value?
I just replaced an outdoor motion activated light for my friend and decided to troubleshoot the old one. Within a few minutes I determined the LDR(photo resistor) was bad. It only changes about 5 ohms between light and dark, and after removing it, the light works again. I would like to fix it because I have a use for it, but the LDR has no markings. With the LDR removed, the resistance of the circuit is about 80k. Any ideas on how to figure out the value?... -

Re: YSUS EBR73561201 clicking off on a LG 60PV400
Checked them all. Last time some were bad, but not this time. I notice VSC is only 12v. Possibly it would be higher if I wasn't using the lightbulb limiter, but definitely still quite low.Leave a comment:

Re: YSUS EBR73561201 clicking off on a LG 60PV400
Good job! I found two bad resistors, and two more bad FGPF4633s on the Y smd Z boards, but I still have a short somewhere on the Y. I use a lightbulb in series with VS ro limit current so I don't blow the replaced FETs. It's odd because it lights dim, then goes out, and that's the expected behavior, but then about a second later the bulb comes on bright and stays on.Leave a comment:
