TELEVISION TECHNICAL BULLETIN MODELS 51CS03H 59CSD8H 51CS05H 66CS03H Month of Issue: Classification: CTV2000 06 07 June 2000 White Page 1 of 1 59CS03H 66CS05H 59CS05H 66CSD8H SYMPTOM 1. Intermittent failure of one or both of the vertical supply line fuses (R631 and R632). 2. Frame rises up when warm until there is a large black band at the bottom of the screen. This can eventually lead to the 'rainbow effect' at the top of the screen. 3. Line tripping (same symptom when the Megatext IC goes faulty). 4. Slow to come out of standby. CAUSE Breakdown of Q707, causing variation of the main 5V supply rail to the vertical stage and Megatext IC. This problem can be checked by measuring the voltage at the emitter of Q707 during the fault condition. Note that Q707 can fail when C714 is replaced, so it is recommended that C714 is changed at the same time as Q707.

This leads to the set drifting off tune, either on one channel or all channels. CAUSE ACTION Changes of tollerances in the AFT circuit. Readjust the AFT circuit as descibed in the adjustment service manual. This is duplicated below for reference. 1. 2. 3. 4. 5. Place the set in the service mode. Apply a colour bar pattern to the RF input at 855.25MHz. Press the standby button on the remote control. The set will now undertake the AFT adustment automatically. Turn the set off by the mains switch to cancel the service mode.
