Crown XTi Power On Failure Repair in 16 Minutes

I've found the exact same problem with many Crown DSi and XTi series amplifiers that fail to power up. This is a followup to my previous video - today I found myself fixing 5 amplifiers, and all were fixed with the same simple capacitor replacement.

Buy the replacement capacitors here:

Higher-quality Panasonic ones can be found here:

And the cheapest ones... use at your own risk...

It is, in my opinion, a design flaw of these amplifiers, but the fix is super easy. Disassembly and reassembly is the time consuming part, but I've got it down to 15 minutes or so per amplifier.

Not into electronics? Well there's no time like the present to learn! But don't try any of this at home unless you know what you are doing and are aware of the extremely dangerous voltages that can be present inside a power amplifier!

I appreciate all the feedback on these amp repair videos, but please keep in mind I do not do repairs for a living and I really can't provide answers to your questions.

If an amp is not literally sitting on my workbench, I cannot diagnose it for you. Please consult a local repair shop, I only posted my videos for entertainment purposes. I do appreciate the views and the comments but again I can't really provide any more assistance than what is already in the video..

This video just saved my company over 2, 000.00. I was able to get my Crown CDI 4000 working for less than 10.00 in parts.

You sir, are the quintessence of a gentleman and a scholar. A thousands thanks for sharing your expertise and experience!

[crashedcorvette]

Thank you so much for this perfect video. To the point and no meaningless information

[vintagetubeamplifiers]

I just got 2 CDi 1000's, a XTi1000 and a XTi 4000 to repair with the same problem, thanks!

[thehighwayman]

Awesome, this looks promising! I have one of these and as you can guess the same problem basically. Powers on then shuts off immediately

[danielrank]

Thank you mister, worked on my Crown 4002 XTI!

[johnmorris]

You are very good with your hands, intelligent also

[ajssoundllc]

Worked perfectly as described. Thank you!

[robgracia]

thank you for the advice going to try it see if I can do it I have an xti 4002 that won't power up as you described

[pablocontreras]

Excelente video, felicitaciones gracias a este video arregle mi amplificador

You can actually twist the cap out from the top, unsolder the leads, clear the solder holes with a vacuum station & solder the new part in without having to remove the board at all.

Thank you for your help. I removed the motherboard from my xti1002 with no difficulties but I failed to take a picture before inverting the board and the 2 metal straps on the board supporting the speaker binding post were not captive and fell off. 1 remained on the positive terminal but not sure if the other was on the other positive terminal. Can you enlighten me please?
Thanks Ed

Also need replace burn precision resistors. The amp works but in short time failure again without replace those resistors.

[robertcsims]

Have the XTI 1002 and does not power on. Did the capacitor replacement. No change. Tested removed capacitor and it was good.
Tested resistors and the show resistance. Tested all the transistors, 1 tests bad . The one right next to the 2 relays. Do not know if that could be the problem. Any advice? How do I know what transistor to use in the replacement. Looking for the schematics and parts is tough to locate. Thanks for the videos.

[rickymanonsen]

Is this the same for the xti6000? I have 2 with the lcd flashing on and off and will never power up. Thanks.

[sammcr]

Have you worked on the Crown CDi1000? I have a unit that will not complete power on and does not have the set of through hole resistors and the C198 near power switch that you replace in your video. Really like your get right to it video style. Any advice? The only thing observed on my circuit board is a bulged capacitor top (C815) right near the back of the LCD display. This has a small inductor and other small SMPS components.

[robertfilimonchuk]

Hi Justin, thanks for the video. I have an I -t6000. That has a flashing power indicator. And sometimes will just turn on and off. Do you think it’s the same issue?

[michaelshaw]

Do you check the two zeners D28 and D29 which live in parallel of this cap, they limit the startup supply to 32V.

[Rafiki]

I have a no power XTI 4000, is the repair the same as the 1000? Also do they use the same replacement capacitor that you are suggesting? Thank you for all the help.
