Modern AVRs are typically like that, some HDMI chips run very hot and to make it more silent they forego the fans. Essentially they're cooking themselves to death. Problem is these chips are not sold anywhere or needed to be coded to specific models/functions.

Maybe ask him if he has any older models up for sale. I tried repairing some, if it's just a normal analogue related part, it'll be an easy fix, unfortunately... alot are digitally-related and they usually go through a DSP (Dolby/DTS). If this fails, no sound will be output through speakers. Plus, older models would have repair manuals/schematics up for references, but now its getting less and less available. The future is disposable, serious.

i always heard ppl complain the "HDMI board" always spoil

the trick that i use were, putting a 12cm fan on top of the AVR to suck air out from the back portion of AVR to keep things cold.

yes indeed....the in build fans are gone to exhaust heat. The only FAN is still available in most of the AVR is a miniature fans that provide some airflow to those heatsink design to cold down resistor.

secondly...it might be also due to where the AVR being place. lots of ppl put it inside cabinet with very restricted airflow to the top mesh for it to vent heats.

and who daheck necro old tered :x

my  denon model is 1910 model...very low end  avr...but since need for hdmi... i bought lor..selling my old skool marantz ..regret action

I still have my marantz SR5000. I use it for my PS4. The sound is better compared to my previous sound bar. I sold my soundbar and using the SR5000 till now. Only the video carries the HDMi. The sound using analog using the amp. I seldom sell my old unit. Just using it for different purposes.

agreed with you...my marantz sr7500 sound really good  but no hdmi...really regret selling it lng time ago due to no hdmi

HDMI mainly is for the video source only 😉

my  denon model is 1910 model...very low end  avr...but since need for hdmi... i bought lor..selling my old skool marantz ..regret action

See above..

Btw if denon and marantz spoiled and after warranty .. not worth fixing .. expensive like hell
