Glen may be right about C5003. Not for holding a charge, but discharging to
quickly. If the source voltage to the CRT cathodes goes away right at turn
off, the tube is forward biased before video has a chance to cut it off.

| Glenn - The only thing I could suggest is you may have a elect. cap.
| holding its charge - such as C5003 on 200V supply line. Good luck.

| Thanks to everyone for all the replies but I know what afterglow is.
| Adjusting G2 has no effect and if the chassis is swapped then the
| problem stays with the chassis and not the tube.
|
| This started happening about a week ago according to my customer..

| This is normal (according to Thomson/RCA) You have very good emission in
| the tube
|
| At worst you may need to decrease the G2 control

| Hi all,
| Have a 27" ctc177 with a spot in the middle of the screen that slowly
| dissipates after after the set is turned off. Picture is normal when
| turned on.
| I dont see a spot killer circuit anywhere in this set and wonder if
| anyone else has come across this before?.
|
| BTW, if the power plug is pulled as opposed to turning set off from the
| control panel then there is no spot in the screen.
