43H71 43 In Projector

Several days ago I ask whom every could help me.On the broken LINES on the bottom third and top third of my of my green gun all though my red and blue guns can be be adjusted the general belief that one or both of my the stk392-110 wre fried and replaceing them my problem would be solved.I know a semi retired tv tech that has been working on sets since the tube days told me that these two moduals are for red and blue convergance only
and it would not help my green line.he pulled out a board showing the
modules and he even marked them red and blue.being I told him it after a half an hour warm up and I lined up all 9 crosses.the following mouring the green was off again and know after 48 hours only the 3 laterial center crosses line up.he told me to clean the connections with brake cleaner
and if I can't get it the green gun to behave it,s probably ready for the junk
yard .On the other hand he gave to 392-110 he had laying around,after his last heart attack he sticks with tubes and flat screens.I have taken the screen,back and front for better access,after turning down the lamps .i can clearly see the lines in the gree gun.Question#1 if I put in these chips will it fix the green ,if NO WHAT IS MY NEXT STEP?

I'm no TV tech, but the reading I did on this subject said the 6 amplifiers in the two STK392-110's are used for horizontal and vertical on the RED, BLUE, and GREEN channels.

Images on tv are green sony 60 in projection sxrd-

If it's bright green with light lines from side to side the green gun is shorting out. You would need to take the front off and look at the neck of the tubes. See if all three filiments are working. It will be a dim glowing in the neck of each tube. If you have filiment voltage but no red gun you may have bad solder connections on the CRT modules but being it's a Sony it could be a bad green Tube. If the green gun is shorting out call around to TV shops in your area and ask them if they have a Beltron or BNK Picture Tube Rejuvenator. Sometimes the short can be cleared using the right test equipment. Ask them how much they would charge you to shoot the tube if that's your problem. If it's no Red it may be bad solder connections on the CRT modules. I hope this helps.

KP51ws500 turns green and shuts itslelf off

There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.
