A friend has run an update on his Panasonic TV which has resulted in the machine not starting. A technician has determined that the mother board has been burnt out. Is it possible that an update can cause this, and is there any way that he can confirm this without spending more money for a second opinion?

Bricked yes, burned no.

May need a better / different tech to repflash / replace the ROM

Maybe get hold of Panasonic and see who they recommend in their neighbourhood.

Thanks for your help, sorted by removing the power lead, pressing the on button, and turning the tv back on. Done

I hope he didn't pay anything for the technician to tell him it was "burnt out"!

Certainly not my own personal experience (never had any reliability issues with the various Panasonic TVs we've owned over the past 20 years, which have been a range of plasma, LCD and OLED) nor does this match Consumer's appliance reliability survey (last updated Feb 22). They're the only brand to get 'excellent' for reliability; not too shocked to find they get only 'good' for satisfaction as their 2000s interface is disliked by many.

What's the basis for your claim?!

The past 20 years have become meaningless as Panasonic have given up manufacturing TVs themselves and are using TCL. If TCL get a poor reliability rating for TVs they put their own brand on are Panasonic's made by TCL likely to be much better?

Some people get burned once by a brand and swear off it for life.

I’ve dealt with multiple brands and Panasonic have been the worst for board
faults

HDMI ports dying
Main boards dying
The power supply boards are a constant problem with not booting the tv and just showing flashing red lights, you have to unplug the tv for 10 minutes to fix it

I have a Panasonic 2021 TV and am pretty happy with it. Granted, most of the content comes through Chromecast with Google TV or Amazon Fire TV, but their apps work fine.

Back to the OP's question. Good that you solved it by doing a power reset. That tech is full of crap, as a software update shouldn't be able to "burn" a motherboard - unless by that he meant corrupting the firmware, and he just used "simple words for simple people."

In any case, this "tech" was probably looking at getting good money for a bigger job that, as you found out, wasn't needed.

old mate is an electronic tech who fixes them. also i caught up with one of the guys i used to work with who is a salesman and even he did not recommend them (tho i had already bought another brand before talking to him).

i'm a little bias in favor of panasonics. i used to be a repair tech fora F&P, panasonic dealer a very long time ago.

My $0.10 is that Panasonic TV's simply aren't what they used to be, but there's a lot of goodwill in the market for the brand.
