Trying to Save - Samsung 65" The Frame (QN65LS03B) with no signs of life (One Connect Box)

No they go much slimmer with mini led also. At the price they are they should be that. Plus every frame TV I've had is super thick.

Anyway glad we nailed down a common failure. Thx to the guy who originally told me about it back on that other post.

Are you reselling this one or keeping it

if I had to use a ocb, I would drill some decent vent holes all over the cover, so the damn thing could breathe. Then just hide it behind something if looked too funky, at least it might not fry itself all the time, very bad design. Did that to the tank firestick, no problems after.

Yes, BIG thanks to you guys.
That thread of yours saved this TV from the recyclers.

I have saved 3 Frame TVs to date and have kept them all.
Love and utilize the ART function on them....more than i actually ever watch TV.

I am really looking for a smaller one 43/55" (2022+) to go in the dining room.
This is too big (IMO) to go in the intended spot but I might hang it up there until the one i really want comes along and needs repair.

I actually had a 4th defective FRAME TV come my way (bad backlights) but I lost it on the operating table bcos I didnt know how to disassemble it and cracked the screen.
I'm still pissed about that one.... and it was the perfect size although it was an earlier model (2018?) so it was was much thicker than the newer ones today (to your point about thickness).

Anyway when the 12v cooling fan comes in I will post pics of the upgrade.

As for the underside, i removed most of the silicone and put a thick thermal pad there to help keep that side cool(er).
These are the thermal pads that were on the sustains of old plasma TVs. I was always impressed how thick they were (10+mm!).

Yeah when I find a failure and a random TV I try and post it here just to help everyone out as they have helped me out. I've learned a lot from here and fixed probably 400 TVs now realistically it's probably more like 200 but it seems like so many

Just buttoned this up.
Added a 12v 25mm fan, a thick thermal pad to the bottom and a good dab of thermal paste.
I went ahead and tapped into the 5V rail of the USB port bcos the fan running on 12v was way too loud for my liking and USB port only gets power when the unit is turned ON.
I secured the fan with thick double sided adhesive taped (to minimize any vibrations) and found a good spot near the cover where there were vent openings and a clear channel (on the board) to move air.
ChatGPT says that blowing cool air INTO a space is more effective than pulling hot air out so I orientated the fan to blow in.

Even without all of this the hottest components (resistors, etc) were only warm to the touch but this upgrade should alleviate any thermal related issues in the future.
The next owner will not have to worry about this issue at least.

I think I will also upgrade all my other OCBs with this little fan as well.
Thanks guys (@Eazybone in particular) for the assistance!

Nice work, you're the first one here that I've seen modified this poor design, I bet it lasts a good long time now.
