Samsung UN55D6003SFXZA

[PeteTait]

I have a Samsung 55" LCD. When you plug the TV in, it powers up displays the samsung logo and then displays HDMI2 in the corner. After this the TV does not respond to anything. I can touch all the buttons on the front of the TV and i get the red little acknowledging it sensed my button push but the screen does not change. The only way to power down the TV is to unplug it.
From the reading i have done is that the problem is the main board. Is there something on the main board that is the problem or is the only solution to put in a new board? There doesn't seem to be any instock that i have found. Can i use a different main board?

Any help would be Great!

Do you get a picture when you apply something to HDMI 2?

Re: Samsung UN55D6003SFXZA

No, i have tried blueray player and a cable box on the hdmi2 input and there is no picture.

Sounds like firmware. It's a lockup condition. Eeprom failure or nvram.

Turn off the TV and get a hair dryer and heat up the main board. Especially around 8 pin devices.

I tried the Oven at 385 for 10 minute trick and that didn't work. Would the hair dryer work differently?

Re: Samsung UN55D6003SFXZA

Yeah the oven trick is a really bad idea. This problem manifests itself from a faulty regulator not something that's not making a good connection. What you would be doing with a hair dryer is temporarily heating up and IC well it's still hot. Then powering on the TV

Re: Samsung UN55D6003SFXZA

A hair dryer on the eeprom sometimes relieves it of the lock up condition or something wrong because the eeprom esentially internally damaged.

By the way love your avatar! I heard about a new super troopers movie! I gotta see it!

Re: Samsung UN55D6003SFXZA

So powering up while still hot, is this only a temporary or permanent fix? or is this a way to test?

Re: Samsung UN55D6003SFXZA

A way to test. You could also try this.

Re: Samsung UN55D6003SFXZA

So i took a hair dyer to eeprom, and then turned on the tv. no change.
I also tried the eeprom reset (unbricking) from the wiki website and again no change.

Thanks for the avatar compliment. I have been waiting for 2 years for the new movie to come out.

Re: Samsung UN55D6003SFXZA

Damn.. stubborn board. Well I vote on eeprom or nvram issue. These D series boards seem to have alot of issues lately. What is your VCC on eeprom voltage reading anyway?

[PeteTait]

Re: Samsung UN55D6003SFXZA

VCC is reading 3.3

Re: Samsung UN55D6003SFXZA

How about service mode .

Mute-1-8-2-power

What happens. Lock up in service mode too? If not do a factory reset there

Re: Samsung UN55D6003SFXZA

So.. I don't have the original remote control for the tv. :/

[freakaftr8]

Re: Samsung UN55D6003SFXZA

Don't need the original remote as long is the channel buttons work the mute button works in the power button works it's all you need with a universal remote.

Do you have any Samsung TV remote? Any Samsung remote will work any set

Re: Samsung UN55D6003SFXZA

That should note that the D series main boards had serious problems with NV ram also. I managed to get my D series that I have out of boot loop by heating the hell out of the eeprom and the NV ram. It has been one year and it still works good. Not saying that your particular TV is going through the bootloop problem but I think it all stems from the same issue, Yours is just taking it a little further than mine did

Re: Samsung UN55D6003SFXZA

That was a no go. I am not able to power the tv off. The second i plug in the set it turns on. The only way to power it off is to unplug it.

[freakaftr8]

Re: Samsung UN55D6003SFXZA

Hmm well I don't know. I just finally have up with mine and got mad and started heating the hell out of the nvram and eeprom. At that point I didn't care anymore. Tha5s when it started working. Lol

So i know which one the eeprom is but which is the NV ram? I will take a Hair Dryer to both of them again and see what happens.
