Don’t see any on that side. Need close up pics of the other side of buffer board. -
A reflow on this chip will not work. These boards need the processor replaced.
I believe Nicks TV has done a yt video on these models and the processor problems....Leave a comment:

Never seen 2 spots that needed to be covered. You can try covering more pins or fewer pins. But honestly this is just a bandaid and not a permanent fix.
this is the downside to this kind of repair. There’s always going to be some type of loss in the picture quality. Either lines like you have or some type of color loss or both.
good luckLeave a comment:

If I’m not mistaken these LG TVs “LF” series had problems with main boards. In particular the cpu overheats and goes bad. I don’t recall anyone reflowing one to fix it either. Have to replace it unfortunately.Leave a comment:

Usually horizontal lines are indication of screen defect. Could be bad cap on the buffer boards also. Check all caps on thereLeave a comment:

You can still use one remote. The fire stick and be programmed to your tv to turn on and off and control the volume and switch inputs. Or you can you the Samsung remote and control the device with CECLeave a comment:

Just buy a fire stick or similar. Smart TVs suck in general and a stand alone device will be much better and cheaper along with no headache...Leave a comment:

I agree, seems like all you need to be a TV technician these days is a roll for scotch tape. lol...Leave a comment:

Isn’t that what I said? The chassis is ground...Leave a comment:

They just need the quantum dot filters to make them white again. lol...Leave a comment:

It’s most likely back lights as you mentioned since that’s Sonys code for backlight failure.
You can ground the wire named backlight err to the chassis and that should bypass the shutdown so you can verify the tv works and confirm it’s the backlights.Leave a comment:

The believe it’s just the tcon information you need. But since you got the other one working in service menu you can take pics of it and copy setting to new boardLeave a comment:

You got the wrong board. You may be able to change the setting in service menu but need to know what your original setting/ tcon info wasLeave a comment:

There is a winbond ic on the panel buffer board. Have you tried reprogramming that one?
Also you may want to post your original ic files here and see if Lotas can look at them and see if they’re good. If they are bad he can fix them. Sometimes downloaded ones from the net will not work. Doesn’t have the right info on them for your panel/ tconLeave a comment:

Never heard of using hot glue around BGA chips. How does that help? Seems like it would cause more problems as the chip wouldn’t get any air flow and dissipate the heat. Which seems to be the reason these chips fail in the first place.
Seems like a proper reballing with lead solder would be enough...Leave a comment:

Most likely the manufacturer. Some are made by Samsung, LG, AUO etc....Leave a comment:

Sounds more like a software issue than a screen problem to me. Might be emmc going bad. Usually panel issues the tv won’t turn on or is in a constant reboot.Leave a comment:

Unfortunately It’s trash. Needs a new panelLeave a comment:

I have 3 of these TVs also with same problem. Just to note I had 1 working board and tried to swap ic from good board to bad one and it didn’t work.
After switching ic’s back to original boards the good board no longer worked and had same symptom.( no standby light and no power). So make sure if you order a new board you get the correct one.
keep us postedLeave a comment:

There is only 2 TVs Samsung made with these edgelit panels on the side. The JS series you have and the HU series the year prior. Every other tv edgelit is lit from the bottom. You may get lucky but usually TVs this old all the diffusers are in bad shape some way or another. Will never be perfect again...Leave a comment:
