Question about Toshiba 36A50 36" TV
Eventually, we will get a picture.
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.
