No Picture or Sound <br /> <br /> 1. Check transformer. <br /> <br /> 2. Check power supply circuit board. <br /> <br /> (a) Check PL10 <br /> <br /> (b) Test voltages <br /> <br /> (c) Check diodes. <br /> <br /> 3. Check RESET button operation. <br /> <br /> 4. Check IC15 properly seated. <br /> <br /> 5. Replace IC15. <br /> <br /> B. No Sound <br /> <br /> 1. Check TV channel timing. <br /> <br /> 2. Retune modulator. <br /> <br /> 3. Change IC20. <br /> <br /> C. Faulty Colour <br /> <br /> 1. Adjust RV1 (and RV2 if fitted). <br /> <br /> 2. Alter value of C7. <br /> <br /> 3. To obtain full green screen or to cure &#039;rainbow effect&#039;, fit a 2-22 pf capacitor trimmer instead of C7. <br /> <br /> 4. If colour fault on 22&quot; or 27&quot; SONY sets, then fit 15K resistor across Pin 4 of IC9 to Pin 4 of IC10. <br /> <br /> 5. Change IC9. <br /> <br /> 6. Change IC16. <br /> <br /> 7. Change IC12. <br /> <br /> D. Garbage on Screen <br /> <br /> 1. If RESET switch cures fault, then change IC17. <br /> <br /> 2. Change IC15. <br /> <br /> 3. Change IC17. <br /> <br /> 4.
