Oh god, the voice control on the UE46ES8000 is terrible. It's a complete gimmick. Too slow and only understands a few phrases. Turn it off.

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

Found this little tidbit on another forum...

Well, I would like to officially report that after 2 years and 3 months my $2800 Samsung has ran it's course. It now does the infamous "Turn on and turn off". Really pisses me off that a TV with a SOLID 1 year warranty only lasts 2.5 years. Now I get to deal with a repairman which I'm sure will charge me as much as he possibly can. Samsung is garbage and I won't be buying it in the future. Really makes me wish I bought that $400 best buy warranty. This was the 55es7500 btw.



UPDATE: Apparently Samsung realized that the lead cable from the power supply to the mainboard were inadequate on the first batch of ES7500 (as well as 8000's) and made changes. Basically it fails and fry's one of the pins causing damage to the power supply board. The serviceman replaced the Power Supply Board and installed the newer version of the lead cable. The lead cable was all black and beefier than the white cable it replaced. TV works great now. If there is anybody in the Santa Barbara County area that needs assistance, try Ross TechnologySolutions out of Bakersfield. They ordered that parts and had it installed within 3 days of contact. BTW, my symptoms were exactly like the ones posted earlier in the thread with the pictures of the weird lines.

Yea, the TV was stable long enough to turn this option off.. Didn't fix the problem, though..

I am Googling my brains out trying to find info on how to reset the TV to factory default...

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

At the shop, it was set up on a generic universal stand with one set of mounting screws..

When I brought it home, I had to use a different set of mounting screws for the wall mount. The screws were a tad short so I had to put significant pressure to get them to engage and hold the wall mount..

I took the TV down and removed the wall mounts.. Just for sheets and greens, I powered the unit up..

Sum beach, it worked fine!!

I let it sit for 5-10 mins... Played with the settings and the Smart Hub.. Went back and forth... Everything was working great..

Let it sit for another 5-10 mins while I wrote up a big long "WOOT!!! IT'S FIXED" post...

I said, "OK, let's really put this puppy to the test"....

Connected to the WiFi....

5 seconds later it froze up.. Rebooted.. Now doing the same old same old...

Some days it just does't pay to get outta bed...

Then i would suspect the main BGA processor of cold joints. Try reflowing it and see if it gets any better.

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

Apparently this TV has been worked on..

And someone went to Michale's School Of Replacing Screws On PCBs

The ES8000 I have shuts down if you access the YouTube app on the Smart Hub - I guess the extra processing power required causes a slight voltage drop!

[Michale32086]

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

Well, I pulled the back cover and disconnected and reconnected all the cables.. Replaced the screws that were missing from the Power PCB...

Powered it up and it looks good. I tried to play ANGRY BIRDS, but couldn't figure out how to "push" the button to play the game..

Got OUT of Angry Birds and the TV is still on and good..

Going to try to connect to WiFi next...

Yea, once I get WiFi connected, I am going to test YouTube....

[Michale32086]

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

Connected to WiFi.. Stable...

Watching a YouTube Video on some alien artifact in the Antarctic...

So far, so good...

[Michale32086]

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

Well, I think I may be able to count this as a win..

Went thru a half dozen YouTube videos, no prob..

Changed some settings.. Good ta go...

Doing a firmware update now....

[tom66]

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

Don't do a firmware update until you are CERTAIN it is stable or you WILL BRICK THE TV if it crashes during the update!

[Michale32086]

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

Yea, good point...

It seems to be good.. Gonna put the cover back on and put it back on the wall and see how it goes for a while..

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

so you think it was a dirty or poor connection then?

[tom66]

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

I'm wondering the same thing as my ES8000 did not have a burnt connector but reseating "seems" to have fixed it.....

[Michale32086]

Re: This Time.. It's Personal.. Samsung UN60ES7500 Constant reboots

I think it was a, what I usually refer to as a, C.A.R.E. problem..

Cosmic
Alignment of
Random
Events

Otherwise known as "stuff happens"...

As with Tom's there wasn't any burn or char marks or another to look like it was overly stressed..

The only thing I really "did" was to re-seat the connections.. Everything else, the wall mounts, the placement, the connections.. everything is as it was...

And I just finished GUARDIANS OF THE GALAXY in 3D without a hiccup...

WOOT!!

Quite possibly, Samsung produce unreliable TVs so I would be very hesistant to keep one of theirs.
