I have a buddy with a 5 to 7 year old Toshiba 27" TV. Can get model if needed. Across the top of the screen for aprox. 2" there are several lines. You can also see a shadow of the current program almost as if the vertical adjustment was off but the picture is square in the screen no colapse noticed. No distortion at the bottom. No noise or other distortion. Has been like this he says for many months. Ideas Smokey?

Hi, I have a Sony STR d-990 stereo receiver with, what I think is a broken power supply. One of the fuses on the PS keeps blowing. It is in line right before one of the lead wires to the large transformer. It is 6.3A 125V fuse. The other fuse on the board is 3 . 15A 250V but it does not blow. There is a small transformer and a relay on the power supply board that both work. The transformer sends 5V from the board to the front panel of the receiver and gets a switch signal of either 5V (off) or .75V (on) from the on switch. The fuse blows when the switch is turned on. There is 120V between the fuse contact and the other lead to the big transformer when it is off. When the fuse is put in though, the two leads to the big transformer dont have any voltage between them. Then when it is turned on the fuse blows. I don't know if this is of any importance or just a normal circuit thing. The large transformer has 0 ohms resistance between the two power leads when there is no voltage. I don't know much about the elctronics of it, but my feeling is that it is a short of some sort in the power supply circuit or in the large transformer itself. What can I check to narrow down the problem more? Is there something that happens often in these receivers? Any help or suggestions would be really appreciated. Thanks Sam Sarcia
