Zenith Z56Z95 RPTV picture is red
I sold my TV to my neighbor a month or so ago & the picture was fine,
but I was over & now the pic has a reddish cast to it. I'll get it fixed eventually (the tank of the toilet on my second floor cracked & flooded all 3 floors), but I was wondering about what cost I'm looking at & what could possibly be wrong. Any advice would be appreciated. |

Did the flood affect the TV or was that just non-information you
provided about the toilet?? H. R. Hofmann |

Find the red screen control and try turning it down a bit, That should
remove the reddish cast. Then, the questions is is the set stable, or does it continue tio get red with time. You can fix the other stuff while you are waiting to see if turning the red screen down is permanent or not. Bob Hofmann |

Zenith Z56Z95 RPTV picture is red
Find a dumpster and throw it in. A bad CRT (picture tube) is very likely in
these things. Sorry. "Asimov" wrote in message ...

Bob Hofmann Ch Thanks. What do you mean by red screen control? Is this in the Ch service menu or something on a circuit board? I'm not a tech, but I Ch can get into the service menu. Ch Could it be not too much red, but maybe too little of another colour? Ch The menus appear greenish when they should be yellow. I'm not sure Ch what colours would make up yellow. Ch Chris Green and red makes yellow on a CRT. If what should be yellow is greenish means it lacks red. On nearly saturated colours it means the red drive is insufficient. However, the red cast symptom means the red threshold or bias voltage is off. The 2 symptoms might be related, for example if the red driver is faulty. Then the red bias is upset and the red drive or gain might be too low, both together. But it might be something completely different like a shorted red gun. A*s*i*m*o*v ... You may be a tech if you're entertained by a 6-pack and sparking HV. |
