TV Samsung UE55HU8500L (2014) – service menu + firmware reflashing advice needed

**Davi.p** · 09-27-2025, 05:37 AM

Lotas there are codes for LG and Samsung, The Samsung ones enlarges some already big menus, Samsung menu has 3 level of menu access, the stanard one, the Advanced section with password and the full menu, he needs the full menu access to be able to give the write command next to panel type to enable it, this is what i remember..

I do not know why but the window with the panel type seems to lack some items, try to access the full menu by entering the service remote key, even by portable device + ir blaster + wav file (i have the files) , so you can unlock the panel type & front color write options..

go to samygo.tv and you will find complete entry service menu Photos to compare

Maybe the problem is the panel number, you write 55A1UU8EH but the data says 55A1UU9RH. The OCB sees a different panel than and maybe therefor the tv resets.

Yes, you have some strange model in the menu, it should be like this.

Don't confuse LG with Samsung.

Why bother with such complications? There is a special remote control AA81-00243A, and it costs pennies.

It's up to the thread owner to decide, where is the problem? The less the items the less confusion and earth pollution

And before doing any manipulations in the service menu, you need to make a backup of the eeprom 24C256 (512), so that you can return everything to its original state, as it was initially, otherwise you can change something in the settings and after that the TV may not turn on at all.

You're right, William1967. You must have looked at the wrong panel in an internal menu;
that was from other tests. It's actually the first option, though of course, I don't know
if that one is correct either, but it's working well. Thank you very much for your help
with the issues I mentioned.

Hello Davi.p, thank you for the very quick response. Your information is extremely helpful!
Despite that, I'm lacking some technical knowledge—I'm not sure how to use the .wav files
you sent me. I will look into it, but even if I manage to access the deeper Service Menu,
I will still be missing the correct values to input. Regarding the Service Remote Control,
I will look into how I can purchase one. Thank you again for all your help. Kostas

Hello Lotas, your note and the hint with the image you sent really woke me up, because
I was taking that panel for granted and wasn't paying attention to the model listed there!
Also, the image of the remote control was very helpful. Thank you again. Kostas

Hello Diah, I will check Samy.go.tv and I hope to find something to save my old but really
very good TV. Thanks a lot, your help, like everyone else's, is invaluable

Not that difficult, you need a smartphone or tablet and a IR blaster, it's a simple 3,5mm mono or stereo plug with a resistor and a ir led, you can purchase it on eBay, it's 1-2 euro thing, or you can make it by yourself, it needs the stereo plug, an ir led taken from old useless remote commander, and a 100 ohm resistor, well i used a 20 ohm but it works only on my old phone, i don't know why, from tip ----resistor----anode---cathode----ring.. Put volume to maximum ad go close to the tv receiver, you need to be already in service mode, if you use stereo plug, join center ring to gnd ring, you have to play the wav file by a file manager like total commander for android..
