Dead Pixel on Mitsubishi WS65-813 RPTV ?

Archived from groups: alt.tv.tech.hdtv (More info?)

To answer your questions, yes your warranty should cover it. Yes lenses can
and do get dirty over time. Once a tech of ours found a fried spider on a
lens. It might also be dirt/dust/bug on your mirror also.
Either way, get a service call done on it to rectify the situation.

Let me throw in a comment here also, before you call the repairman. I have
a RPTV (HD) and noticed a speck on my screen. Mine happened to be white,
several pixels in a random sort of connected pattern. I thought the same
thing, that something must be wrong with the screen, the guns or the set.
I receive my signal from VOOM satellite, and I thought before I panicked and
started calling support lines, etc. that I would just reboot my whole
system. I started with the set itself. (On my set, a reboot is accomplished
by holding down the power button on the front of the set for at least 5
seconds). Then I rebooted the VOOM stb unplugging it for 30 seconds. When
I powered all systems back on, the "dead" pixels had disappeared. Try this
first----
