TCL 4-Series Panel Swap?

[x_orange90_x]

I cracked my panel on my 50S421 replacing backlights and I found a tv online I'd like to use as a donor if possible. The model in question is a 50S434. They are both in the 4 series and obviously both are 50". Does anyone know if the panels are the same or close enough? The only difference I see is one is Roku and the other is Android TV.

I don’t think it’s compatible. Also there are several versions of these TVs that use different tcon boards between them.

That's true, there are way too many variations. I believe my 421 has a TCON and the 434 does not. This means the 434 scaler boards would have the tcon components on them I believe whereas the 421 wouldn't.

If I can get this tv cheap enough it might be worth it to swap the panel and the boards into the other one with new back lights. That is if the mounting holes are the same.

I don't see how it's cost effective to make 7 different versions of the same tv using all different part configurations ��

I just checked ShopJimmy and apparently there is a 421 WITH a TCON and one WITHOUT it. I have the LDAA which has one, so I guess they're not compatible.
