I own this great Tv for 6 years (purchased Dec 03).
Replaced 1st bulb a year ago. Didn't have any issue until now.
For last couple of weeks, after TV is operating for while (few hours), image start to flicker, with little white tone on some part of the image when it does that, almost like some colors are flashing in white (not all screen, only a few of the image elements)
The frequency of the flickering increases until the TV shuts off by itslef, and all 3 lights sensor are blinking as TV is Off.
The TV can be restarted and then operates normally if you wait after a while.
To avoid that currently we turn off the TV for a few minutes when flickering starts, then we can Tv again for a good 45 minutes before the flickering starts again.
I ordered and installed a new replacement lamp but it did not resolve this issue.
Seems like flickering is now starting earlier by the days, started after 3 to 4 hours of operation and now it first starts after only1 1/2 hour.
No unusual noise or click is noticed at any time coming from the TV when any of this is happening.
Also just in the last few days, the Temp sensor light alone goes on (permanent red) after a while, , while the TV is opreating normally, even before the flickering starts.
it is starting to become very frustrating to have to shut the TV off every 45 minutes...
