Lol Panasonic uses LG OLEDs. If it happens on LG, it'll happen on Panasonic. Just like it'll happen on Sony and Philips as well.

I believe LG is usually the cheapest in this region.

Extended warranty is a subjective choice, that's up to you. I bought my 77" G3 without extended warranty, neither did I with my previous 77" C9.

What plasma panel?
Plasma panels hasn't been in production since 11 years ago. 

The "first grade" panel or whatever the fuck they told you is the the MLA OLED EX panels that LG is already using on the LG G3. Panasonic MZ2000 is Pana's 2023 flagship model, which uses the same MLA panel from LG. So much for being a "reputable" shop when they can't even give accurate info.

Panasonic's only advantage is that they adhere to industry calibration out of the box better than LG.

Usually that happens because the seal between the panel and OLED substrate is no longer intact.

Nothing really you can do prevent it.

It can happen 2 days after you buy a new unit or it can happen 2 years later. How are you going to determine QC in that context?

My GX 65 top screen border seeing dead pixels. Claim extended warranty.  Was quoted with replacing with Sony A80L 65. But I decided to upgrade to 77 hence ended up I top up to get the A80L 77.

Awaiting for my LG A3 65" to be in tommorow to replace my current 55" X90H in living room. Officially shall start my OLED journey with the budget model 1st. 

I'm using LG C1 48" as my PC/PS5/Xbox display

Also recent noticed that there are quite a number of dead pixel at top there
Viewing angle no issue but once seen, cannot unseen 

86" is bare minimum for living room movie watching

hisense QC might be a problem as below

for tcl, the price for 75" C845 (other model is crap) is approaching 86" QNED86. Might as well go for LG branded. TCL still QC not as good as LG.
U7K have Bad backlight bleeding.

The technician go to his house and said this is normal for hisense

is it worth buying 77in C3 2023 TV now since 2024 might be here soon.

was quoted between 16k to 17k for this, good price ?

It does come with 2xgold bar and RM 388 TnG

thanks for the update, 6.2k , might as well get a new unit then.

luck also i guess especially for OLED. some i see can last more than 6 years. some 1-2years die already.

No doubt it's going to be a heartache if the OLED tv dies after the warranty expires. Or it might not happen at all and you get to enjoy all the best picture quality. 

I don't have a C7 but one of my relative is still rocking it since the day he bought it with no burn ins and damages.

Correct me if I’m wrong, typically dead pixels show up/develop within the first few hundred hours of use right? Does extended warranty really safeguard against it? Also don’t they have like a threshold of number of pixels per square inch to qualify for replacements?

How do I buy the warranty if I'm purchasing the TV online? The shop does not sell it.

It's only been since last couple of years where we're getting consumer OLED displays that can fully reproduce HDR10 (static metadata of 1000 nits). We're still a long ways off from the industry standard of 4000 nits with dynamic metadata aka Dolby Vision (although that goes up to 10,000 nits).

Hopefully MicroLEDs can reach prime time soon.

Most of the OLED TVs that don't have MLA or heatsink tops out at around 800 nits (LG C3, C4). Those with heatsink can reach 1000 nits (Panasonic MZ1500). Then those with MLA can hit up to 1400 nits.

Those are average figures, obviously there's panel lottery and they are non-calibrated values.

My own LG G3 after calibration hits about 1350 nits.
