2 Answers

Turns off automatically after 5 seconds. Momentary display of saturated picture and sound from memory. Brief menu display, superimposed on screen. Could this have been caused by a spike on the cable (during a storm)?

    Zenith repairman came out and said that a new picture tube with PCB would fix it ... $585 (including service call). Comcast said that it couldn't have been a spike on the cable, but their insurance provider sent me a check for the repair costs anyway! I think that the Zenith guy had some influence in getting the insurance to pay. ...

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.
