Also wanted to ask about 05 GX470 mark levinson no sound from speakers except for maybe in morning when 1st start of day, last maybe 2 seconds. I'm assuming it's the amp, but I can't say for sure, what would your diagnosis be from my description. Tia

This guy knows his craft, I can tell and those who are talking down have no idea. I appreciate you brother keep up the awesome work, I would love to have u do some work for me but your half way across the globe.

I need mine fix can you tell me where to fix it like you?

I am trying to fix my ML amp too. The FETs on the power side are blown. The number on the FET is N348AB but I cant seem to find a cross reference on the internet. These are the 2 FETs beside the 2 rectifiers on the small heat sink close to the biggest toroid. Any help is appreciated.

Jomar I have a 05 GX470 mark levinson same model number amp 86280-0w041 and no sound from speakers, bluetooth works but cant adjust the equalizer except for when I sometimes start in morning and it works for a hot second. What could this be? Faulty amp? or short somewhere? I am hoping from watching your videos you would know. Thanks in advance.

Hi! i was wondering if theres anyway to output a bit more power from this amp like an upgrade. I want to see if i can get the system a tad bit louder and maybe more bass.

Hey Jomar, my Mark Levinson amplifier in my 2012/13 GS 250 has part number '862800WA10'. But it looks like most of the US models have '862800WA00' (same except second to last letter is '0' instead of '1'. Do you know if these are cross compatible? They look exactly the same, and both are Mark Levinson amplifiers for 2013-2015 Lexus GS.

What is it that you are actually changing

Do you know of a way i can bypass the mark levinson amp so i can run a secondary more powerful amp to power all my aftermarket speaker upgrades i replaced in the car? Im always blowing a capacitor or fuse inside of the amp. The lexus relys on the mark levinson amp but its not strong enough for my new speakers

Hey Kamusta brother I have a 2013 Lexus gs350 pioneer amplifier the sound from speakers intermittent cutting out can't raise volume or change treb,bass,mid or speaker position. I pulled the fuse from passenger side and it was a little burnt on the sides the metal contact but not blown I replaced anyways But issue still happens Do you know what I should look for?

Hi , i have. Mark levinson 86280-0W140 it is stop working, can i replace with 86280-0W041 instant of mine? Everything looks same but different model number ? Thank you 🙏

I have a 2002 lexus ls430 with the ml system all the speakers work ok but not enough bass also the sub isn't working I did try and tap it to see if any weird noise but nothing .... not sure what the issue is -___-

Very nice, any way I could ship you mine? Just bought an LS for 3 grand and I think the amp is fucked

i would like to know how much you would charge me to repair my amplifier for my ls460?

Is this permanent fix ? Do you have guarantee for your work. Thank you

There is a problem with the screen, and the front and back control sometimes does not work, so is this device responsible for that

Привет, у меня такой же усилитель , но есть проблема ,из динамиков идут помехи (журчание) проблема 100% в усилителе , как можно это решить ?

Автор ролика ответьте в чем была проблема? Как вы подключаете усилитель на столе его проверить невозможно без головного устройства . У вас не запускался преобразователь напряжения+-28v ? Автор сделал вид что поменял транзистор 🤣. И всё заработало. Не верю
