Re: toshiba 36afx61 tv
You have a cold solder connection on the vertical output IC or in the sweep power supply that feeds the voltages to the vertical output IC. You can download a service manual from here: http://www.servicemanuals.net/results.aspx?type=SM&brand=0&model=36AFX61 Good Luck

A few questions: Are you using this TV directly on a cable line of do you have a cable box or satellite receiver connected? Do you have sound and no picture on the AV inputs as well, or only on TV channels? Is there anything on the screen or is it completely black? Has the picture collapsed to a single line across the screen? Is there a picture but it's distorted? Does the on-screen menu and channel number display properly?
With a little more information I might be able to help you with this.
Just Connect signal to tv and run autoprogram. Or use video input jacks from converter to tv ( yellow,white and red video in ) and select tv/video on tv pannel front ( don't need remote control) I hope this work for you.
you probably just need to resolder the vertical output IC. It will be mounted on a heat sinc. probably 7-10 pins. Part number may start with "LA" like LA7845 or similar, there are others though. You will probably see the rings around the solder joints on the bottom of the board. Good Luck
Not acutally a solution.
We are having this EXACT same problem; it started this week. Let us know what you are having done. I've called Toshiba and service reps but they are all quoting a price which is almost half the value of the tv. Have you been able to fix it? We are pretty upset since the 2year warranty recently expired. Obviously, it seems that others are having this problem as well. Email us: firstname.lastname@example.org
