mainboard replacement for LE46C750

Post by mk83 » Mon Aug 07, 2017 4:03 pm

Hi,

I'm having problems with my Samsung TV and I'm gonna change mainboard for it. TV model is LE46C750R2KXXU with mainboard BN94-03388F

I have looked ebay for used mainboard several months without luck but I found a mainboard for 40" version of my TV, LE40C750R2KXXU with mainboard BN94-03388E so I decided to buy it, but is it safe to try it in my 46" TV?

If the 40" mainboard works in my 46" TV, what should I take into consideration? Should I change many values in service menu? Does it affect to picture quality if its not 46" mainboard?

I just bought the 40" mainboard from ebay and I will get it on this or next week.

No problem because of size. Any 32-55inch mainboards are cross-compatible. So - good luck!

Ok, thanks. I have also question that how can I enter to extended service menu? I know that I can enter to service menu pressing INFO+MENU+MUTE+POWER but I cannot change there example local set/region? Do I need to enable hotel mode or what and how?
TV has T-VALDEUC-1016.0 if that matters.

I just noticed that there are different models for psu too for 40" and 46" models.
40" have psu BN44-00340A http://www.ebay.co.uk/itm/BN44-00340A-S ... SwzlNZh0AY
46" have psu BN44-00341A http://www.ebay.co.uk/itm/POWER-SUPPLY- ... Sw4CFYv-af

I understand that 40" and 46" mainboards have own code for mainboard because of different settings, but why would they do different psu too for 40" and 46" models. Arent the settings same for psu for 40" and 46"? PSU:s also look different for 40" and 46"

But I think 40" mainboard may work with 46" psu?

Psu power supply unit. 46 inch needs more power than 40. Dont you think?
And i imagine it may work with 40 as the outpult voltages are same for both.
