very informative video sir. Are you still in UAE ?. Can I bring my amp for repair. sometimes it works and sometimes it doesn't. How shall i contact you ? Thanks
Hello sir, my audio is making a constant buzzing/beeping sound, I took the amplifier apart already. Can you give me some pointers please? Like which pings should I test? Thank you 🎉
Hey so the issue with my 2007 ls460 is that I get no sound when trying to play CDs. They load and eject just fine. They also play just fine, as in you can see the track timing advancing just fine as though everything is working, just no sound. The sound from my radio, Bluetooth, auxiliary, and navigation works great too.... Just no sound when playing CDs. Do you have any suggestions as to what the problem may be and how to fix it?
@@kuarashi I've only had the car for 6 months but it doesn't appear that the head unit has ever been opened. Could it be the blue color socket on the end going into the amp? It would be much easier to check that first! Thank you very much for your reply
Hello have same amp, issue : amp works ok for 2 second then cracking sound, while music cuts in and out , then static noise even with radio off mode. If i disconnect and reconnect radio wires it works good for 5 seconds or so. any ideas what could be the issue. thanks
I have exactly same problem. It can be very frustrating. When the system was opened, no water but there's Rust. So I have it clean. I will pick it up tomorrow and test it. Will give you feedback
@@kuarashi thanks for the reply! I had a guy repair mine so he said, my sub and front door speakers still don’t work no bass at all and my volume doesn’t even get loud anymore. He said it’s the head unit..any help on this? Been longer than year now.
the mosfet irf5404 shorted replace it, and change some od SMD resistor 2pcs 1k and 2pcs 4r7ohms, and check the SMD 3watt resistance of 8R2 if equal to other
@@kuarashi Tol pareho nyang ginagawa mo dito. Ok naman ang speakers . Check ko yung power coming in may 12 volts. Ano kaya ang possibilities na nasisira. Minsan bigla na lang umaandar. Salamat Tol.
@@kuarashi Dito ako sa California. Marunong ako ng konting electronics. Retired na ako. 74 years old na ako. Yung nasa picture ay apo ko. Gusto ko malaman ang mga test point ng amp baka sakaling makita ko. Salamat Jomar. Ingat.

Is there somebody open your head unit?? I think blue color socket from the back of radio same with the amp is lose, check that cable like an antina

Check inside if theres any sign of water or rust, then chck the small system board

When the system was opened, no water but there's Rust.
So I have it clean.
