Wow, wonderful community here! I'm hopeful one of the extremely gracious souls who frequent it can help me keep our family's 7year old Maxent plasma running. I've searched through past threads here for a couple hours, but haven't found precisely the issue I'm seeing and so am prevailing on the charity and knowledge of those who have helped so many others.
So, the rundown:
I purchased this set in Jan '06 and have recently had an issue with the display. The first sign of trouble was several months ago: The image on screen would flicker a few times from cold power-on before recovering and then remaining clear. That behavior persisted until last night when after being on for ~50 minutes we suddenly started seeing vertical bands of noise across the whole display. (See attached photos.)
This noise will start after the set warms up with a few dozen pixels going wonky across the whole display and within seconds progress to what you see in the photos, sometimes with more or less noise. It is a pretty consistent pattern once it appears, though it sometimes disappears entirely for brief periods (a minute or two at most).
Another clue to whatever the issue is: If I "tug" on the set (wall-mounted) the noise will sometimes disappear entirely. Alternately, it will sometimes increase in proportion to how much I move the set.
The noise does cover the OSD. It appears on all inputs, but only while searching for and displaying a signal. If no signal is detected after a couple seconds, the set displays a clear blue screen.
My ultimate question is: "Can I fix this myself reliably for less than ~$600?" I do not have the luxury of tinkering endlessly, and don't have the skills or tools to solder, but I am capable of re-seating cables or purchasing/replacing a board if there's a high probability of success.
Thank you for any insight!
Bob
