TCL 65S450F no logo, bleeping sounds?

Actually any smart tv that isnt hooked to internet is dumb tv, you can disable or delete some if not all apps they come with easily, so as long as not online no problem if thats what someone wants. Bonus side effect is the eMMC will last much longer since it doesnt have to work so hard.

You said it before, a monitor and a tuner. Here you don't even need the tuner, because unless you got satellite or cable tv you get chit OTA.

Yes if you have a satellite device or cable but what about if you want to get free tv signal what do you do for this

The other issue is that with a monitor you are limited to the size of the screen as well because I think that the largest screen size that I have seen 32” inches what if you want a 65” monitor then what do you do

From this post I do not think there is a way to take a tv set that is made now and make it a dumb tv set is there because I would like to have a big screen for my shed but if it needs to be hooked up to the internet this going to be an issue for me because I do not want my battery testing machine to have any ACCESS to the internet what so EVER because of security reasons for the version of Windows operating system that I am using because I do not want to risk of being hacked and some one causing mayhem to my battery testing machine and causing my shed or house to go up in flames you might think that I am paranoid no but I know that it possible and I do not need someone if they are seeing if you could be done I do not need to be asked for this issue when I know how to avoid it in the first place

Because I have had the battery testing machine on one of my 65” tvs for a little while but would not leave it on for days on end but after thinking about the fact that the tv set has access to internet was not a comfortable place to be and after a few months of doing this I stopped doing it this way and went to monitor instead

I did a quick google search and the biggest monitor that you can get is a 39” inch screen but you are going to have to pay for this size screen

What about the version of the firmware that is on the replacement board that you got is the same version

This is poetic that a brand new tv would have a bad main board and you had to replace it to get the tv to work properly wow I know s**t happens but this takes the cake for something like this to happen but at least you did get a new tv and was told to take the first one to the recycling center they did not want you to send it back that interesting I have had this happen to me before and like you I have had some success repairing some of them before but not always

But like mentioned before in another post I do not know what brand of tv to buy if one of mine decided to take a s**t I would prefer to buy a monitor and buy an external tuner and be done with it I am not a fan of smart tvs I really do not use any of these features because they really do not work very good anyway

There wasn’t much that could have happened to the TV. I mean it ran for a bit and did an update when I left. 10 mins later I come back to this. The chances were good for a corrupt main board. The real problem is to find the right flash for this TV. Never found one, but diah came up with a Google flash and this didn’t work on my board.

I put my 2 cents in at posts 44 and 45, can't speak on monitors, pretty much use tvs for all my monitors.

Contemplating throwing my big screen out the door, seems like they forgot how to make a decent movie as of late, SO many clunkers, "Poor Things" wasn't too bad tho.

[CapLeaker]

Yes I'm glad it was the main. I like success stories. I just bought a new 83 OLED. Very excited. I have asurion insurance and they paid me out $2000 for next TV and got an 83 OLED for 2400 new out the door with taxes. Couldn't pass that up. Sold my old TV for 800 and now I'm ahead!

And here I go with my measly 65" TV that cost me 66 bucks. I guess I am doing something wrong. lol

Haha. After 3 months your new tv!! Good news

Took 4 weeks to get a new board from the southern States to me. All in all I guess 6 weeks from when I started. But it cost me CAD$ 35, plus another CAD$ 31 = CAD$ 66 for the whole smear. Perfect!

Nice, glad to hear it, was hard to believe mainboard went right out on a new tv, I hope you get some good use out of it.

Thanks to everyone contributing! Well, this is my newest and biggest TV now. Never had a TV that big.
Before I forget it: the 55" and 65" TCL uses the same main board and I haven't to do anything to make the 55" main board to the 65" screen.

[CapLeaker]

disconnect it from internet and disable auto update lol

No chit, that's exactly what I did!

Finally this TV is fixed. Got a new main board, chucked that in, turned the TV on and SUCCESS!

let try again...
the file of upgrade or V999.img you put it on USB stick MBR mode fat32
the file i give to you at post 101 factory_update_param.aml change it by add the file name you have in .img format
for example

--wipe_data
--wipe_cache
--wipe_media
--update_package=/sdcard/v999.img

or
you can download from the link i gave before zip file and let the ,aml format in this way

--wipe_data
--wipe_cache
--wipe_media
--update_package=/sdcard/updatw.zip

use the same way you did at post 104

Nope... no go for me that way. I think the only way to do something maybe is over that factory programming port on the main PCB.

[Diah]

I know it is polling an IP address from the router. Problem is the TV is starting something every 12 seconds or so and there is a bleeping sound. It isn't fully rebooting but it seems the TV is trying something and failing. It's the weirdest thing on a TV I ever saw. It is there, but yet it is not accept anything besides an IP.

I would be very interested in if when you put the new main board if it will do anything more than what it has been doing

Ha! I am waiting for that result too!

[sam_sam_sam]

The only thing I haven't done is to put a TTL on the main board and see what's happening. I don't think there will be anything fruitful coming out of this. It's just another week for the replacement main board to arrive.
