LG MU42PM11 Repair Can't Post
Hey all, i've got 12 of these Plasma TV's in my shop for repair. We don't typically fix plasma TV's, mostly standard computer monitors and slot machine boards, etc... but they've all got the same problems, the screens have faded out so bad that you can barrely see a ghosted image in them.. They have been on 24x7 for about 2 years, i suspect that they are at the end of their life span.
I've got a set of the schematics and the "troubleshooting guide" which only help so much.. Replacement boards are insanely expencive and swapping boards out of a known good screen is difficult, mainly because the last 4 "good" ones are mounted 20 feet above the casino floor.
Anyone have any advice?
Thanks!

Anyone have any advice? or are these things just toast?

17000 hours of continuous use has probably used up all the plasma gas. they are not re-gassable so its a day trip to the dump.

Cool.. I'll post up a pic of the "stack" before they go. Atleast they're being replaced with 42" LCD's.. Hopefully they last a bit longer.

The weird thing is that i have a few 42" NEC Plasmas that have been going strong for over 5 years with no maintenance.


Thanks,
Dave
