Toshiba 32AF42
Hello,
Hoping someone here can help me. I've searched for hours in other newsgroups, but nothing comes up. Early yesterday morning, I was watching a DVD on my two year old Toshiba 32AF42 TV (similar to this year's 32AF44). I've got a Toshiba DVD player and Expressvu satellite receiver hooked up through S-Video cables. Within 5 minutes, the entire screen went white. The best way to describe it is as though there is a white veil covering the screen and you can see the blurred images (sort of) behind the veil. My immediate assumption was that the S-Video cable was shot, so I tested the Expressvu connection - same result. I then noticed that the Toshiba green menu items (Brightness, Color Temp, Contrast, etc) were also hiding behind the veil, which logically would mean that there is nothing wrong with the source (DVD or Expressvu). Small panic ensued, because my warranty expired 2 months ago, so I began fiddling with the connections: 1. Hooked everything up through composite 2. Unplugged the TV for 12 hours and tested again 3. Hooked up a VCR through the front composite inputs 4. Gave it a couple of love taps Nothing worked. So I turn to this forum for guidance. Can anyone tell me if they've seen something like this before? Does it sound like the tube or something else? Sorry for the long post. PS. The sound is fine. |

It looks like by coincidence your TV set has a fault that developed. Since
the screen become over-bright, this can be a fault in the high voltage multiplier, or the bias circuits to the CRT, or the CRT itself. If you are not experienced and equipped for doing TV servicing, you will have to call the Toshiba tech support to send over a service person to give you an estimate, or bring the set down to them. -- Jerry G. ===== "x1mlf" wrote in message om...
