Re: Samsung UE65h5400AW Won't Turn On (Has Red Standby Light)

I have only had to do this once, so I'm not an expert, what I did was go to the update page of support and it tells what model tvs that the firmware will work with, then I bought a mainboard from one of the models on the list, my suggestion is to look at that list. I can not guarantee of course. I would check and see if this one is on the list, my guess is that it is: https://www.ebay.co.uk/itm/363726013....c101113.m2108

here's a hot tip, download and save the firmware, EVEN if you don't need it right now, these guys are notorious for taking firmware off their site, never to be found there again.

Downloaded the files, good tip!
Unfortunately I don't see a mention of other models for this firmware file.

Should a new main board fix my tv?

Re: Samsung UE65h5400AW Won't Turn On (Has Red Standby Light)

Pretty good chance it would, in my opinion.

This tv has been revived, thanks guys!
Put in a new motherboard (literally new.. came from new broken screen tv), for €80,-.
So this tv is good to go for years to come!

(The board on the photo is the old one that came out)

Check the voltages on the converters on the motherboard.

I have a same faulty board with an overheated IC206. Do you know the type of this IC ?

Maybe you even have an electric schematic?

I don’t have a diagram, I have a service manual, but it doesn’t have a diagram.
