Hi, just wanted to add my thanks for this post. My IPR1600 had channel A die on me a few months back just as I was setting up for a gig. Thankfully only one channel died and I was able to use ChB to drive monitors (only one monitor mix, but better than none! Just got around to plucking up courage to desolder the suspect IRS2092 chip and replace with one that I had to order from China via AliExpress. Not my favoured source but unable to get them from anywhere in UK or EU. Based upon your info I took a gamble and ordered a pair of them for abour a tenner delivered. There seem to be lots of high power class D amp modules for sale from AliExpress all based upon this chip so I figured there was a reasonable chance they would be OK and anyway without it half the amp was dead anyway! Success! seems to work fine - just need to soak test it for a while now, to build up confidence in it. For what it's worth to desolder it I started by dumping a line of leaded solder and plenty of flux on all the pins with a soldering iron, then I used some tin foil from an old pie dish to fashion a mask to protect the surrounding components and used hot air to bring the chip up to temperature to melt the solder and lift it off the board. Clean up with more flux and desolder braid, then pop the new one back on with the soldering iron.
john, thanks so much for this video, i have had an ipr1600 sat on the shelf given to me with this problem... though someone thought it was the smps psu film capacitors and removed them.. it was given to me without them! I have no idea what values they should be - i doubt you still have the amp now but do you have info on them? circuit diagram etc? It would be most handy! It does sound like the previous owner had shorted one of the output terminals and then it just did this after so - maybe a warning to people, dont short your output connections!
In general, If the lamps blink it's a problem with the Amp section ( the driver IC is doing that to protect itself and it is not usually the problem). Any steady active lamp with no input usually suggests a power supply problem going to the amp section but the PS is working.
Hi John. Thank you very much for your contribution. I'm from Brasil, and I have a IPR 3000. With your video, now, I have a direction. I see the hot Mosfets and change two. Very hard with the board heat dissipation. It was cutting the sound for temperature. Now, It is sounding the repeating clip sound. I think is the IRS too, but is not clear for me... Sorry my english... Did you changed the OPA and temperature sensor?
Hi John, Great video. I have an IPR 1600 which has a temp failure on channel B. Can you provide the chip numbers that you used to repair the problem on your amp? Thanks!
Hey John, Great Video! The 2092 solved one problem but ,I still have a channel signal light that stays on. I can't find a schematic for the ipr 1600, any thoughts? Thanks!
thank you, I got the same failure but now is completely burned started doing that but now is totally burn, I got a second one but it only shows DDT light in A channel but is nothing connected in that channel, but in Chanel B...did you what is wrong with it?
I don’t know if unplugging the fan would have caused another issue on the temperature rails etc so stopping it was my first choice. Thank you for your comments.
John, Great Video ! Love it ! I Have an IPR here on my Bench and Trying to Figure out why its Burning in the Power Supply Area...Trying to Identify this Part and I see the exact Part in your Video, BUT you didnt ID it .....Can I email you a Photo ??
@@JohnB-2021 In The power Circuit, There is a TALL Blue ( looks like a wire wound resistor ?? ) Very Strange looking thing....On My amp this thing is burning up ...wondered what this was used for ? If I can post a Photo I would ...wondered if you can tell me what this thing does ?
Hi John, sorry to bother u again, i recently sent my ipr2 7500 to replace IRS2110 chip but the guy lost a little silver capacitor (C1060) near the chip, by any chance do you know the value, for some reason in schematics they dont put the value. I think the capacitor is also present in IPR1600 as C66, I think is also know as bootstrap capacitor for IR2110 VB connection.
@@SideBUnderground If you have the pdf schematic, at least for the IPR1600 I discovered that if you click on a component while viewing it, the component details are popped up - even ones with no value shown on the diagram view.
Hii.. I have the same problem with db tech powered speaker.. I hear clicking sound In HF driver every ~0.5 second.. But, in LF speaker normally working.. I tried to check the components everything is okay.. Do you think should i change the irs20955s ic inside? Thanks
I have no idea, it could be anything. If the tweeter is driven from that ic, you could replace it. It could be the smallest capacitor failing somewhere.
hi i have changed the u3525 pwm ic and i still have no drive output from it, i have the vc and vcc +15 and the gnd, there is a triangle wave from the oscillator output but i cannot get drive from out A and B which go to the ir2110 to drive the power supply fets! do you have any idea what could be causing this issue? original fault was blown output fets and drivers and blown power supply fets, it does nothing other than heat up the blue resistor when power is applied
Just curious, I have a Peavey IPR3000 and the DDT light on the A channel stays on and I have no output on that side. Any thoughts? I don’t have the guide that comes with the unit. Sorry to bother you, I know you’ve fixed a couple and thought you might have an idea...
Hello John. I have 2 xIPR1600, and they come from the USA, There they have 110 volt, bud in Italy we have, 220 volt. Is it possible to change them? Thank you
There are 2 lugs marked LUG1 & LUG2 I believe they are linked for 1 voltage and you cut the link for the other. That is all I know. I do not know if anything else needs to be changed.
I have 6 7500 with a dead Power Supply. I replaced the 2110 chip and power supply MOSFETs and some diode etc and it still doesn't power up it just restarting continuously. any suggestions?
@@danielparkinson5338 I've not seen the circuit for that part but it's designed to handle lots of power which is why it's big and mounted away from the board. You can find it in the schematics and tell me what resistor number it is. Hope you like the gift.
Thank you Don Without a schematic in front of me, where are the uf diodes? I had 2 of these amps, one in the video where the driver was intermittent, another where it was dead. I also had a Wharfedale with a dead IRS2092, lucky because I didn't have the circuit drawing for that Wharfedale.
There are four - two per channel. Located behind the big capacitors (on the other side from the Audio output FETs). You should measure a diode drop across each. Other than one of the blue LEDs opening up and killing the whole unit, this is the most common fault.
Thank you very much sir for sharing. Although late a congratulations to the radiant dad. A sincere greeting from Mexico.
Thank you for your comments, maybe one day I’ll get to see Mexico 😀

Good Job John...i also got one IPR2 5000 which powers on for 2sec and off,you can hear the relay clicks
Sounds like a short circuit somewhere.

Sorry no I don't have that amp, I repaired it and gave it back.
You should give your amp back to the person who removed the caps.
absolutely love your channel!

The temp chips are not engraved are they?
They are LM358's
Hi John . What solder heat torch are you using for the chip removal? as need to order 1 and yours looks fine. Unless you have a better option matey?
It's a snap-on / Portasol or something like that. If you find my smd soldering video, I mention what it is in that.

Maybe your woofer is going short circuit
No connection has been made. Ch a heats up rapidly
It must be oscillating or something assuming you have the right chip and fets.
