i have a xli 1500 and my amp is in fault and i found out that the 24v rail only has 15 volts on it and i followed it all the way back to the power supply could my amp need a power supply board or a new amp board as when i unplug the fans from the amp board the amp comes out of fault and starts working like normal but we all know they need fans ive test probed every part on the back of the amp board and found no shorts in diodes or transistors or rectifiers im at the stage im super confuse also the main transformer has the - 25v rails but after all that the board of the power supply only wants to give me 15volts and i have no ways of jumping out the board to eliminated the amp board to see if i still have 15volts on the 24 v rail.
Dear bro very nice your repairing tips, I have facing same problem in crown xli 3500 amplifier all diode and transistor are good 24v is dropped how to rectify please give me tips
No hay problema, si no es eso, que este anfitrión y gran profesional le dice, revise los mosfets, los que tienen el ala superior plateados, colocados a cada lado de los disipadores que tienes que desmontar. Es un fallo muy común en XLI3500 cuando se hace trabajar por debajo de 4 Ohm.
Dear sir thank you very much your service method is good, I have facing same problem in crown xli 3500 amplifier i tested all transistors and diodes but still problem is there, but I found 24v supply from power and speakers out is getting drops to 15v something. So please give me the saison to slove the problem.
@@TKFElectronics i connected amp in series mode the bulb little glowing at this time removed two fans than there is no short. I checked all spares surrounding 24v reg circuit and fans circuit all components fin but still problem is not slove please give me some hints
Hola buenas ,es bueno este modelo para usarlo en casa con unos altavoses Sonus Faber Principia 7? Tiene calidad de audio o solo es ruido ? Gracias un saludo
@@TKFElectronics I understand his question. I´m having the same problem. The Crown xli3500 uses the mosfet AOT472, but is impossible to get that mosfet, is out of circulation, and u can´t find a replacement in all transistor, because parameters are a bit weird. I bought the IRF1607, but i don´t know if is going to work well. The ID, Pd, VGS, VDS and RDS(on) are similar, but the capacitance is a bit different, i don´t know if it´s going to be a problem. What do you think? Thanks for all, I appreciate your work
Great video sir I really appreciate it keep up the good work 👍 👍 🙏
Thank you very much.

Bro Pls check 24V regulator ckt or 24v Relay ckt

First of all let me know what is the issue in your system bro

My dear viewer what is the problem. Power is not getting ON or no sound problem or amp going in clip mode or what,
@@TKFElectronics Dear bro amplifier is getting on but fault leds glowing and no sound .thanks you for giving quick reply.
Both channel fault LED is glowing
Sure there is some shorting or weak components in pre amp section pls check.
Very good work anna
Thanks Bro
Very nice, well done
Thank you bro
I have a fault 21/99 code in a xls1500, but in the Web I round that it refers to boot failure but I don’t know what part to check or reseting metod
Bro, u can't do anything, send it to service center only

Pls leave your comment in English
Hi sir which shop do u get M7 diodes as i also need shop details please post
Where is your location bro
I have a climp light on, can you help me?
Que medida son los componente malos? Y que tipo de componentes son?
Supuestamente son diodos del tipo smd, es decir, de superficie.
Sabes dónde puedo comprar la placa de salida? Se quemó un canal 🫠
From which country you are from Bro?
Hlo sir
Sir AOT472 mosfet equivalent no please
Bro not understood your comments pls write in detail to guide your properly
Sir LXI 3500 model driver transistor AOT472 is short cannot find, please give me equivalent no or matching transistor forAOT472
Pls visit this site (all transistor datasheet.com) u will find equivalent of if available.

I think bro, take risk.
80N08 ic
Amp class D
???
What do you want bro
Hindi me batao na sir
Bhaisahab English Duniya may sab ko maloom hai, Hindi sirf India may hi hai. Mere foreigner viewers English may video banane ko bolte hai.
ये amp कोणसे calss का हे ??Class AB
Class H
Class D
This amp is Class AB.
