An "antique" plasma TV, very cool. That was probably a $6000-7000 item when it was new.

Nice "NEC"
lol

Check those SMD's on the main board, reseat logic board cable, blah blah, you'll figure it out!
Nice buy

I have a Hitachi built plasma set in the lobby of my theatre. It's been on 18 hours a day since 2004, and has never been serviced, other than a monthly wipe down to keep the ventilation holes open. It looks fine.

i also have a hitachi fijtsu built rca plasma thats work fine a 2004 model. replaced caps in power supply is the only problem. i also added 2 fans one on the y sus and one on the z sus boards.

Fujitsu's hold u well, heck I watching one i fixed right now. lol, they are prone for bad connections on the buffer board connecting to the y sustain. When it starts to glitch too much it will short the SMD transistors that run the vscan to the boards.
