Re: Agilent U1253B OLED display failed

I suppose…. It hadn’t crossed my mind yet to look for a filter. I may do that at some point to see what happens.

Re: Dummy loads for amplifier fault finding

He wanted US$ 600 for it. Was a bit over CAD 800. I do not much over eBay. Only things I really need and can’t find it anywheres… like a replacement OLED for my Agilent U1253B.

Re: Agilent U1253B OLED display failed

Trying to give an update on the display:
So far so good with the drop in replacement OLED on my U1253B. Not sure why, but I like the white display better than the original yellow one. Everything is...

Re: Eizo S2000 suddenly died

Glad you got her fixed. As long as the backlights aren’t pinkish in colour, you get more life out of your beloved monitor yet. Probing the LVDS awhile playing a slideshow trick, saved my butt a few...

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...

Re: Samsung LCD LE40R86BD flickering after 5 minutes

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.

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
