Ive absolutely no idea what the model or the brand is, thats why im confused. So i decided to open a thread here so that maybe others might have an idea. I found something very similar in mouser and it matches my specifications but its common cathode, not anode.

I noticed everywhere else they are selling diff color and legs but i couldn't find the specs im looking for. Any kind soul care to help me on this?... -
Re: Logitech Z906 Power Problem
Ive managed to find the diodes, but not the BL6 LDO. Is it a 3.3v LDO? SOT323-5?Leave a comment:

Logitech Z906 Power Problem
Hi folks, i have some issue with this z906. No power. So i checked inside, the AC side is fine, all working good. Then i moved to DC side, checked all the output voltage. Amp voltages seems to be fine which is 12v, 5v and so on. But the 3.3v standby voltage seems very low. So i knew thats the culprit. After further checking, a few diodes gone bad, which is shorted, and 1 IC i assume its a LDO thats supplying the standby voltage. Ive identified the faulty components but since they are SMD, im having trouble finding the codes. Can any good souls help me? Ive attached the pictures of the parts h... -
Re: Pioneer DDJ-SZ XLR right is distorting
Yeah thats what my friend said as well. Since i only use scope for audio purposes, he asked me to get the 50MHz scope, he said thats more than enough for audio repairing. So i might a portable chinese ones. As i dont use scope all the time, so i dont want to really waste a lot of money on something i rarely use. Been reviewing the portable ones, seems good so far. Does the basic job...Leave a comment:

Re: Pioneer DDJ-SZ XLR right is distorting
Hi just curious, im planning to get a oscilloscope. How many MHz would you recommend for audio equipment repairing purposes? is 50 enough? 100? 200? Cause mainly i will be using the scope only for audio equipment's only....Leave a comment:

Re: Pioneer DDJ-SZ XLR right is distorting
Ive just replaced the mute switches (transistors) - NO GO, still same
swapped components from left to right - NO GO, still same
I'm lost now, not really know what to do anymore........Leave a comment:

Wish it was that simple haha. All jack legs are solid. This is more deeper issue....Leave a comment:

Going to try that soon. Ive swapped almost everything with no luck. Going to pop out the smd transistor and check....Leave a comment:

Re: Pioneer DDJ-SZ XLR right is distorting
Its not discoloration. These caps comes in 2 colors White and Yellow, probably different suppliers thus the different colors but same value. I took out the caps from a DJM same value. BTW, i tested all those caps using a capacitance meter. All near value and correct. No damage.
Any way to test whats going in and out of that IC via a digital multimeter?...Leave a comment:

Re: Pioneer DDJ-SZ XLR right is distorting
I'm just curious. These master L and R signals coming from a DAC chip on the main board. Could it be the problem in that?
Its a WM8740SEDS....Last edited by DjKrish; 05-23-2022, 10:13 PM.Leave a comment:

Re: Pioneer DDJ-SZ XLR right is distorting
Haha thats not discoloration. Certain caps of those comes in white color and certain comes in yellow color. I already replaced, swapped, no changes. BTW, they read fine as well with a capacitance meter....Last edited by DjKrish; 05-23-2022, 10:06 PM.Leave a comment:

Re: Pioneer DDJ-SZ XLR right is distorting
Yes i swapped various cables, all same. Left is good, right is distorting if put full fader volume. The ports are fine with multi meter check. Checked the zener diodes on diode mode, both are perfectly fine and identical on L and R. The protection fuse is for overload protection. Both are working fine and tested fine....Leave a comment:

Re: Pioneer DDJ-SZ XLR right is distorting
Hi this is the link to the service manual.
As for your questions, all my levels are at 12pm. When i try the sound on RCA at same levels, sound is good. But when i try the same on XLR, its distorting. I have replaced the 3 OPAMPS and also all the output signal capacitors. Still no luck. If i go to 1PM, it distorts even worse. Only the right channel is distorting while the left channel XLR is fine.
If i lower the fader, the sound is stable, but if i put the fader to maximum, it...Last edited by DjKrish; 05-23-2022, 02:06 AM.Leave a comment:

Pioneer DDJ-SZ XLR right is distorting
Have anyone repaired here a pioneer DDJ-SZ before? I have a unit with the problem of right channel XLR is distorting. But left channel is fine. And best part? The RCA both L and R channels are perfectly fine. I have replaced all possible opamps in that audio out board and all the voltage measures accurately. Sorry i dont have a oscilloscope to measure the input nor the output signal. I have attached the service manual here. Any kind souls can show me a lead? Thank you.... -

Yamaha RX-A1080 No power
Been having this unit for sometime now but not a single chance of obtaining the schematic diagram online. The unit came with a shot mosfet, some resistors and a MIP004 IC. Managed to replace the mosfet, mip004 but stuck at 2 resistors thats burned. Can anyone please help me identify these resistors? I only have 2 resistors thats not replaced now, the rest all replaced. This resistor is connecting to leg 7 of MIP004.
Could it be 801? 800 Ohms? Impossible to be 108 as thats 1 G Ohm :P...Last edited by DjKrish; 05-18-2022, 11:40 PM.
