Question about Toshiba 43H71 43" Rear Projection Television
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.
