Re: Pioneer DDJ-SZ XLR right is distorting

No, a digital multimeter won’t do much here. All you can do is swapping things from the left channel to the right channel and vise versa.

Re: Pioneer DDJ-SZ XLR right is distorting

Btw. These caps I pointed out should be the same than the other side. So not sure why the discolouration, unless they are bad or got changed.
Other possibilities? I think not, be abuse the bad...

Re: Pioneer DDJ-SZ XLR right is distorting

Well, I think you are going to need that oscilloscope. The unbalanced comes from the master hot, so that’s working. That leaves the master cold. Not much else you can do besides compare or get that...

Re: SONY KDL-40BX440 LCD TV "MAIN_POWER" problem

When a mosfet blows and it’s shorted between all three pins, you need to check out the gate drive circuit as well. STBY voltage is always present and goes to the main board. When you turn the TV on...

If the backlights flicker, turn them down to 60% and see if the stay on.

Re: Pioneer DDJ-SZ XLR right is distorting

Noticed right away discolouration on C767 and C768. Swap them out with those from the left channel and see if the problem transfers.

Re: Pioneer DDJ-SZ XLR right is distorting

Did you try to change the XLR cables around from L to R and R to L, to rule out a cable problem? I still don't know if the broken channel is lower in volume than the working one right before it...

Re: Pioneer DDJ-SZ XLR right is distorting

Good news is that you have an identical channel you can compare the broken one to. Bad news is, you don’t have a oscilloscope, as it would make this problem easy. I think you really need to explain...

I guess they are cheap enough. Some of the cheap cams, the clear plastic rots fast.

It’s a variable resistor.

Re: Eizo S2000 suddenly died

Is the LCD fubar? I mean you got the crystals working, there is activity on the lvds… is there a small skinny board under the LCD? Maybe the problem lies there.

Re: Aerogarden Ultra LED blinking or strobing grow lights repair

If you got a 25w iron, put it in the bin. Get something like 60w to 80w.

Re: Aerogarden Ultra LED blinking or strobing grow lights repair

The caps I’ve got aren’t available at the moment. From what is there at Digi-Key I’d go with the Rubycon ZLH series. You need:
3x Part#: 1189-2241-ND, 25v 1500uF and
1x Part#: 50ZLH10MEFC5X11-ND,...

Re: Eizo S2000 suddenly died

Hmm… go with the oscilloscope on to the lvds, give it an input on the monitor cable (something that changes like slideshow) and look what happens on these data pairs

Re: Eizo S2000 suddenly died

Just for shits and giggles, did you check those crystals? If one of them isn’t working, the monitor won’t work either. Look at the data lines see if there is something going? Maybe bake the board and...

Re: A Shorted wirewound resistor?

Before you go too crazy with this, you also have to understand the tolerances on the resistor and the tolerances on your new DMM.

Did you try touching the tab bonds to see if that makes a difference? Anyone clean the monitor lately?

Re: Log periodic antenna to Coaxial cable... balun right?

The most typical is 300 Ohm for those TV antennas, unless there is a tuning stub or something. If there isn’t any matching mechanism, it plain 300 Ohm. Now if you use twin lead 300 ohm cable, it has...

Re: Log periodic antenna to Coaxial cable... balun right?

Not all log periodics are 300 Ohms. Kind of really need to know what it is. Let’s say it has a 300 Ohm feed point. You could use 300 twin lead and run it inside under the roof, then use that 4:1...
