HT-J4500 home cinema, cycling on and off repeatedly.

[scotchbaz]

Although I've had it a good few years, never having a problem with it, my home cinema system is throwing a fit. It seemed to start when the blu ray/ dvd drawer wouldn't fully extend. I gently pulled it and inserted the disc and it seemed to work okay. The next day, when I switched it on, it now cycles through "LOAD", "No DISC" repeatedly, even when trying to use "D in", "AUX" or any other setting. I've disconected the drive from the rest of the unit, no difference. I've reset the unit whilst it was in stand by mode, nothing. It's not dirty inside, all very clean looking. Anyone know what's going on... Please help.

I've looked over the net all to no avail.

I'm encouraged (very slightly) that somebody got the chat person to acknowledge that the problem exists.  I just did a chat and the person told me that they haven't had any reports.  This is after I explained that there were litterally dozens of people on their own message boards, some of which who have called in, with the exact same problem happening in the last day.

But like other posters have said, any firmware fix might be problematic to deploy.   Hopefully the bootloader does look for a properly formatted USB or there's some vulcan keypress combo on boot.

Confirmed mine was connected via Ethernet also

Mine on internet too,

it must have been some background kill update.

By the way, my model HT-J4200 does not have anymore USB as a input choice if I press INPUT button, it scrolls only RADIO/BT/DVD/AUX , no more USB

I have read some time ago, that SMSNG makes in TVs clock counter, if you have for example 10000 hours, processor get overvoltage and burn itself.Probably something similar is here....

Also same issue in South Africa. Still no update from Samsung on a fix?

I have the same problem started yesterday  but just a note here that makes it a little bit more than a coinsidence is that I have 2 of the same units in my home and now both of them are out with the same problem.  HUM?  sounds like some kind of kill to me to get consumers to replace older products.  I sure hope that they have a fix for this because I dont have the cash right now to replace half of my entertainment systems in my home.  This makes me so angry because I have all samsung tvs (4 of them) and samsung products in my home because I have always been a loyal customer to them.  I have also had this exact same problem about 2 1/2 years ago with my first unit. wich I replaced and now again with 2 of them at same time.

I ALREADY REPLACED ALL CAPACITORS ON POWER SUPPLY, NOT HELPED, THEN REPLACED ALL ON MAIN BOARD    

As electrician, I do not think there will be easy fix for us, as the device continuously reboots, so it can not get IP address and start to download anything now from internet as a fix.

Same for USB. 

The only way will be some kind of USB emergency update, if sw engineers have it in this device.

Thank you for doing this, as it has saved me the bother. I checked the capacitors with a meter and they all seemed okay, so I'll not go down that road. I just wish that someone from Samsung would reply to this thread, at the very least, to assure us that they're doing all they can to help. Really bad public relations from such a big company in my opinion.
