Re: Toshiba 36A50 tv has horizontal line when first...
This is usually due to bad solder connections to the vertical output integrated circuit. Because the part gets pretty hot during operation, the connections can degrade over time and cause the loss of picture. The solution is to resolder those connections. It's an easy job if you have some experience with electronic soldering. The hardest part, especially in a big set like yours, is getting the circuit board out and flipped over to access the solder side. Also, some parts in a TV can store possibly lethal charges even after it's been off for a while.
If you want to try it yourself, the output IC is mounted on a metal heatsink near the middle of the circuit board. I haven't faced one of these in a while but I think the part location marked on the board for this is IC401. Resolder the connections to the pins of this part and it should restore your picture.
If you have some doubts about trying this yourself, you might consider calling a servicer in your area and get an estimate for a repair call. The shop I used to work for charged around $90 for this kind of job, including the trip charge, but this is a number of years ago.

Yes...this TV may be repaired. The line you describe is in the center and is horizontal across the TV. You will need to resolder the vertical IC pins. This vertical IC is mounted on a large heatsink. Under the board you will see there are 5 or 7 pins that will have rings around them. Resolder these. And you should replace two or three capacitors that are next to this IC. A bad cap will overheat an IC and separate the solder grounds. If you can find my expertise page on this website, you will see the repair in more detail. Thanks for asking and show a few hands of support.
This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.
you'll need to replace bad capacitors on the vertical circuit stage , no expensive but you need the basic knowledge, and the tools to do it your self , if not . you need a tech
depend on the tech 60 to 80 dls a shop 125
