GR2.2 függőleges hibák

1. Bad vertical linearity for 110 degree CRT

A.  For mini/narrow neck and black line sets:R3506 becomes 130K (4822 116 52242)

B.  For black matrix sets: R3506 becomes 150K  (4822 116 52245) C2506 becomes 680uF (4822 124 80063) R3471 becomes 75K   (4822 116 52301)

C.All sets: C2509 becomes 1uF 

2. Pic shifted to one side and one half of screen is blank

IC7470 TDA2579B

3. Bad vertical deflection

Check and replace if necessary: Transistor T7502; 4822 130 60775
Resistor R3503; 1.2 Ohm; 4822 052 10128  4.7 Ohm; 4822 052 10478
Resistor 
22 Ohm; 4822 051 10229  27 Ohm; 4822 051 10279

4. Field - lack of height

Tr7546 BC848  sm

5. Frame Collapse and R3503 going open Circuit.

Place jumper (4822 051 10008) on pos.number 4328 on the mono-carier from 25" and 28" blackline S sets

6. The width changes up to 2 cm when adjusting contrast

 2526 (4822 122 32857) leakCapacitors on picture tube panel.

7. Field collapse

R3508 1R2 safety res o/c & check for dry joints around height pot & pot divider cct

8. Field - pic 1" high with R3503 o/c

Replace R3503 - could be any value between 4R7 & 27R depending on model - 10R worked in this case
