Sometime such protection circuit got to do with the power problem from tnb. Incoming high voltage, surge current, lightning, dust etc. It will prompt to act to protect further damage to your unit.

Don't forget to ask the SC what problem when collect the unit.

use test pen to check live--neutral wiring. maybe terbalik

Been using for 1 month no such thing happen. Just curious how much u pay for your A2040.tq

Most AV amps do have such problem when your main earthing have problem.
The best is add a ground for your AVR.

True,

But given hindsight, I would prefer it not being spoilt at all - de dwntime n not to mention de hooking and unhooking de in'connects n cables alone scares me..

Lets see, my Panny digital avr died on me - at least its digital connexion did - analog still ok - weird
My ol Marantz dpl avr went on for at least 4 yrs n then I upgrd to de 4200 n tat went on for anthr 3/4 yrs n upgrdd again to pioneer 911 , which l m still using in a secondary system - n now, latest Marantz 7002 - hmmnn l tink abt 4 yrs now - touch wood - still goin strong....

To me, reliability n durability is important - I wont touch any brands tat has bad rep for tat..

According to the sc the main board is dead. Why the board is dead. No idea. Had been using the AVR with power conditioner but I guess again is unlucky

It is a stabilizer?

I have 3 of it. And I throw it away already. It cause some sort of very short trip/jump voltage sometime. I guess due to lifespan.

I am using bada5500.

What are the 3 models that u have?

Guys, how to prevent the unuse input/output nob for being oxidize.

I paid around RM3.7k.

nice price!!! even cheaper than LX 58 and denon x4100

Why so cheap, i though i pay 4600 aldy very chesp n u got even better deal n mine no headphone. Damm got short change.

I use those normal stabilizer which cost around 150-400. Depend the watt capacity.

I not sure still can get it. I have this cap for nob which come in different size. Just cap those no use. After many yrs, when I take it out, the nob still look like new.

But I have no idea where to get it anymore. Cause brought over 10yrs ago.

Got a guy selling rca protective cap in music garage sales.

Finally got back my avr from Yamaha. 3 days to repair. Good job to yamaha.

Thanks to remind me. Ya, it call rca cap.

The price is . But better than nothing.

I go and korek back in the cabinet and found the remains of it.

Need meh? Can use masking tape or cling wrap or heat shrink. After all is facing rear.

That is quite fast turnaround bro. Well done Yamaha.
