If a 7jp4 lights partially, is it ok??

Both CRTs are probably good. And the fact that you did get a raster indicates that the flyback is highly likely good. And various other hard to locate parts likely are good too. Replace all the paper caps, and check high resistance resistors (above half a megohm tend to go bad to higher resistance) and the electroytics should be replaced too. I'd say that there's a good chance that a resoration should be successful.

Well.... my GE 810 does NOT have a dim raster at ALL!! IN fact..it has a GOOD, bright picture, that is PLENTY bright enough to watch in a well-lighted room. It is in the basement, and there is a 300 watt bulb nearby, when it is on, the picture is still plenty bright enough to watch. Of course, I realize that we are comparing "apples and oranges" here.... a 10" set with a flyback and magnetic deflection and such, compared with a 7" Electrostatic set with RF-type HV. Still...not all of the old round BW sets were that dim!! I expect that with a full raster it (the 7jp4) will be dimmer...but probably still plenty watchable.

BTW-- pictures coming of the 810....maybe tonight, (after hours..)!!
