Question about Toshiba 40H80 40" Rear Projection Television
1. The first couple problem events - the picture sort of warped really weird then it went back to normal. This was over a few days.
2. About a week or so after the first problem events the picture started going to a sort of rolling lines flashing deal after a few minutes after turning on the TV. After cooling a bit it would refresh and do the same thing again. Sometimes it would go back to normal.
3. The TV still usually works for a few minutes but it has gotton worse in that it just goes blank after some flashing and stays blacked out until the next time we turn it on later. Also, now the sound even goes off with the picture most of the time.
I've turned this problem in before once with a little less description. The reply was a little less than I had hoped for.
It sounds as if it is solder related, bur hard to say for sure. You ay need a service manual to actually trouble shootthe power supply and opeating circuits. I will post a lnk where you can get a service manual emailed to you
