UE40D5500 Keeps restarting software problem!

[sigmeyer]

Samsung TV has issue with nand flash , keeps restarting. All voltages present and OK. I disconnected the PWM pin from motherboard connecter and it still keeps restarting. So its not psu issue , disconnecting the Tcon board changes nothing either.
My question is , will reprogramming the nand chip fix the problem? it has a nand chip and i think its called EEMC chip for storing memory. I was thinking to use RT809H programmer to reprogram the chip and hopefully fix the issue or maybe if someone has some boot/flash files i can do it thru USB.
Thanks alot in advance.

I have tried connecting sda line to ground..following online guide to reset eeprom. Didnt work.. now the tv stays on for longer and thats it...anyone can inform me of all the stuff that comes to reprogramming nand chips?

It's usually bad blocks on the Samsung NAND. It will need replacing, the last time I checked a RT809H wasn't able to program the blanks chips.

Hi.
Do you have any programmer?
Do you have tsop48 adapter?
Do you know different of NAND and eMMC Flashs?

You can buy tnm5000 or rt809h with tsop48 adapter.

diif is right. Rt809h not good for rewriting old k9gag08u0e chips.

Uhmm i just saw TNM5000 on ali express and it goes around 2000$ ... that is wayy out of my budget... Can i do this with RT809H ? whats the drawback?
Happy new years yall

Re: UE40D5500 Keeps restarting software problem!

I bought the programmed chip from a local guy.. it fixed the problem. He told me not to connect the tv to the internet or else the problem might happen again... is this true?

Re: UE40D5500 Keeps restarting software problem!

If having the tv connected to internet messes up the nand, then the tv is kind of useless. Your nand did have a problem but just being connected should not be an issue. If you can and don't already try connecting internet with ethernet cord instead of wifi and I would turn off any software/firmware auto updates, I turn all auto updates off just to be safe, you can always update manually when/if needed.
