  • Page 18: Troubleshooting Guide

    TROUBLESHOOTING GUIDE 1. PICTURE DEAD Is the Power right? Check the Power. Is the CCD VCC (15 V, -8.5 V, 5 V) right? Check the Power(L2516, C2515, IC2502). Is the CSP VCC(3.3 V, 1.8 V) right? Check the Power(L2518, IC704). Is the XRST right? Check the IC703.

  • Page 19: Power Is Not Operated

    2. POWER IS NOT OPERATED Power board trouble (DC output is not). Is the rectifi ed voltage is good? Check the Fuse(F1101), Line Filter(L1105). (Around 7 V ~ 30 V DC) Is the output of T1101(pin9) right? Check the transformer T1101. Is the voltage of L2518(3.3 V) right? Check the IC2504.
