What is the life time for the LG 50PT350 panel, it's not written any where


Hi there,

The specification of plasma panel lifespan is somewhat suspect, since the process of determining longevity of the product is based on deductive mathematical calculation of phosphor dissipation, and does not take into account the electronic components and the myriad of problems that can occur.

Whilst all new LG "Full HD" (1080p) plasma HDTVs panels are now rated for 100,000 hours (that's more than nine hours of watching a day every day for 30 years), your 50PT350 panel is only capable of "Std HD" (720p: 1024 x 768 pixels).

As LG have not specified a specific panel lifespan for their 720p models, we can only presume this panel belongs to LG's earlier plasma panel specification of 60,000hrs.

You can prolong the life of your plasma by avoiding excessive use of the Dynamic Contrast & Brightness settings. Sometimes these settings are set to maximum when shipping from the factory, so reduce these settings to a maximum of 60% where possible.

Although plasma phosphors are more resilient to burn-in (including technologies to help prevent it), as a precaution you should avoid leaving static images on your screen (i.e. black letterbox bars, logos, game screens) as these could still leave behind a 'ghosting' image embedded on your screen. Try to watch in full widescreen format as much as possible, to prevent the black sidebars.


Hope this helps....

The most likely issue is that the Power Supply has burnt out, you were able to let it cool at get it to work for a while, but perhaps part of the board has melted enough to cause a short. Repairs will cost approx. $300-500.
