A bad panel question

[batocko]

why plasma panel fail, why develop a vertical line its becuase of heat or aged material problem , panasonic old panels vs new panels its 100000 hours just marketing or its achieve with 2013 plasma models

Re: A bad panel question

It is the driver IC bonded to the panel failing. Unfortunately it cannot be replaced.

100,000 hours is marketing, referring to the panel phosphor degradation rate, meaning after 100,000 hours brightness will be halved.

It's sort of like a car manufacturer guaranteeing the car to be free of rust for 150,000 miles -- they don't guarantee anything else with it.

tom66 driver IC it is a good quality on 2013 panasonic plasma , its the same league like the old plasma or worse how long hours the IC drive can achieve , a high contrast can speed the fail of IC driver or not

Re: A bad panel question

Failure is random and is much rarer than LCD failure.

Contrast does not affect power dissipation: image complexity, however, does. What this means is, the more transitions in the image, the more power. Very hard to reduce this. This is the same for LCD.
