Hi, I have a Fender passport 500 Pro with a very similar issue....not I am the first to hold my hands up and say the repair is beyond me.....would you fancy taking a look?
Sorry, I am up to my ears in design work. If it intermittently cuts out then it should be straight forward for a technician to repair using the video as a guide. Do you know anyone? Where in the country are you?
Good day I need some help, I have a passport venue series 2 and someone plugged it into 240v while it was in 120v and it still works but it now has a volume threshold of half the normal amount What do you think is the problem cause I can’t afford to resend it to the USA for repairs Please help
That is a strange one. It is very unlikely that the over voltage of the AC Power input would cause a problem on the Amplifier circuitry. However it would almost definitely most likely damage the power supply circuitry. The first thing to do is to check the DC output voltages of the power supply. It has likely damaged one of the HV reservoir capacitors to break down causing an symmetric imbalance in the operation of the main bridge in the PSU. I wouldn't run it until you have checked out the caps. If you have an auto transformer you can set it to 110V and try it briefly on a 110V AC supply. If this works then it confirms the diagnosis as slightly damaged reservoir caps don't manifest on 110V supply (the large 400 volt ones).
@@razenby when it was plugged into 240v while it was in 120v I managed to turn it off with 3seconds but it did smoke a lot, it has been working totally fine, just can’t turn up. I’ll do some research on what you suggested
@@musizbystokes OK. Likely the res caps are leaking or blown and if it smoked you should be able to see where it came from. The power supply chip covered in this video is a common weakness.
@@ekindman They do that, There are two PSus - a big bridge one to power one for the Amp and one based on an infineon PWM chip. The most common fault (10%) is the infineon chip and its associated components. When I repair one now I automatically replace tit wit the latest version. They suffer fractures of the gossamer thin tracking around the connectors pins on the Mixer/input/control board. Rocking or being at all forceful with the plugs will crack the tracks so watch out.. In general this model is a bit of a pain to fix. First isolate the input board and make sure it has power and is routing signal to the amp. Then you can rule it out and concentrate on the power board. I have fixed around 30 of these and I remember that the first few took quite a while. There are definitely other amps that I prefer to repair. Do you have a schematic?
@@razenby thanks for the video, i contacted full compass for a replacement board assembly and ordered the chip you recommend. could you post a link to the schematic?
While you were discribing the primary 90w supply, i mentally jumped to p.c switchmodes. They also have a primary standby supply that fails, usually the crapacitors. Supprised i'm not :-D Get some tea down your neck.
God bless you, very good, I want to please know where I can get the part of the amplifier for that same system, mine did not bring it.
You are welcome. Exactly which part do you need?
How did you take off the front of the mixer? I have a broken pot but can’t figure out how to open that up
To be hones I cant remember. Just check around it, Remove all screws that you can see on the panel and any jack socket nuts.

i want to replace ALL of the transistors and triacs in between them, where to get them?
www.LCSC.com , RSWWW.com, Farnell.com, Digikey.com, UPC.com take your pick.

@@razenby ok thanks I’ll check it and let you know the progress
can you tell me what is the correct voltage at the 5 pin connector as in the clip at 0:34 ?
No sorry the kit isn't here at the moment. Is it powering up and cutting out?
@@razenby mine is powering up and in protect mode

@@nathanokeefe9169 What is your email?
Any chance you can share the SMPS/PA schematic?
I think I have it, Email me.
@@razenby YT keeps removing email addresses
@@razenby treygerman
Hello. Please; could you share the circuit pdf? Thank you.
What is your email address?
Привет
Have a plate plane ?? Pls I need because I want fix it
Sorry what do you mean by 'plate' ?? Please advise.
While you were discribing the primary 90w supply, i mentally jumped to p.c switchmodes.

Supprised i'm not :-D
Get some tea down your neck.
PC power supplies are generally very well engineered. These days it is FETs and the drive circuitry....
My fender system’s transformer is burned, How can I buy? Please tell me!
That is a very unusual fault. I think you will be forced to get hold of a replacement or faulty board.
Do you know from where I can buy?
Any news I m from India
your fucked my guy
Nice video, but overload on commercials on it.
That's the price of the info... If you can get it elsewhere with no ads then watch that instead.
Sorry about that. How many adverts do you think would be reasonable?
@@razenby thanks! max 3 ? I’m not anti commercials. Your time is money, i understand.
@@drabara OK. Ill take look on the long videos.
