You have a magnet purity issue with the CRT. Either the internal degaussing is not capable of eliminating it, spot magnets are improperly placed, or the shadow mask is lifting off the tube in that corner. These are things that are possibly physically wrong. There is also the possibility that...

Resolution is ultimately determined by the bandwidth of the chassis, and not necessarily the dot pitch of the phoshor. If the electronics limit signal bandwidth, high frequency detail will never reach the CRT for reproduction.

Sorry to hear that Deborah. What about reloading all the channels...not luck there, either?

There won't be any...get out your "tweakers" and start looking for pots. :frowning:

Deborah, Did it work?

Not sure if this will work, but it's better than a stick in the eye... Try unplugging the sets AC from the wall, and plugging it back in a few minutes later. If there is any type of digital control on the chassis, it will reset it. Then, try reloading all the channels back in (channel memory...

One significant problem with the THX optimizer is that it is in the corner of the screen. Light fall off on CRT based displays can be as much as 3 to 4 times less than in the center of the screen. When you adjust for in the corner on a 65" RPTV, you will probably be boosting the Contrast WAYYYY...

The SD-582-HD5 is not an Elite, is well removed by date from being just recently discontinued,and, is the same price at COSTCO out here in the West new in a box. $1,995.00, with the option of inspecting it in the store before acceptance for burn-in, with a 5 year warranty is more like a deal...

JoanPablo_T, I am the Runco Southwest Field Tech, so this isn't the first time this has been discussed! ;)

7" CRTs, not 8" (Runco is still a bit red faced about that). It will need to be driven by a scalar to produce the image to die for, and should be set up by someone familiar with that chassis, as it is not for the novice. If it is in nice shape, you are in for a treat, if the price is not too...

David, What were we using in ISF seminars along with the Loewes? Was that a Samsung or a Sampo direct view? It was incapable of being accurately calibrated. (Mysteriously it was absent in Phoenix...any explanations? :) )

You are in terrific hands with either :emoji_thumbsup: :emoji_thumbsup: Highly recommended!
