I have a Toshiba 50HDX82 that I bought 4 years ago next month. The first year and a half or so it looked great, after some AVIA/DVE tweaking by me. Soon after that it developed the burst of color on shutdown that was common on Toshiba's of that era. (I got an extended warranty for that reason) Soon after that, the flickering started.
Called for service, and a green CRT was ordered. That took about a month to get. Installed, cleaned optics, focused all 3 lens, and it looked very good. About 6 months later, the green burst at shutdown came back, and it did a blue burst a couple times one day too. Called service again, talked to same tech. He called Toshiba, they said replace all 3 CRT's, and the boards that plug into the neck of each. Ordered parts, waited nearly 2 months this time. Replaced all 3, cleaned optics again, focused again, tweaked grey scale by eye, and he left. Looked good, but when the room got darker, saw too much blue in the black. Went to service mode, and lowered the BCUT a few notches, and it looked great.
All was well till about a month ago, when I accidentally hit the touch focus button on the front of the set. When the tech did the SM convergence, he didn't save the settings, so when I accidentally ran it, the convergence was way off. I mostly fixed it in the SM that day, but didn't really go into detail to fix it till last night. After I did, I watched some stuff on INHD and UniversalHD, and it looked excellent.
I've been shopping for a new set, cause I want a 60" for downstairs, and to move the Tosh upstairs. I've been looking at the Sony A2000 series, and the Samsung 87W series. Hard to tell without comparing against mine, but I have my doubts that the A2000 series is any better than mine - the Samsung may be. The 60A2000's I've seen in multiple stores look soft on people's faces when compared with the HLS6187W. (Or other sets next to the A2000. Just saw a 60XBR2 today next to a 60A2000, no question the XBR2 shows more details in people's faces.)
Part of the reason I want an upgrade is I need a table model set so I can put the components underneath, then it will fit on the short wall in the living room. It looks wierd now.
Hmm, long story. Short version: CRT holds its own against the newer tech, even on a 4-year old set that's been serviced twice.
