Picture rolls untl il warm - Toshiba 27A33 27" TV

Hello

Picture rolling is due the fault in the vertical output section of your TV. To rectify this fault, you have to open your Tv, and locate the vertical output section inside it. It is so easy to locate as, there will be four wires going from the deflection yoke, that is the coil fitted on the neck of the picture tube, out of which, two of them will be thick, usually coloured red and blue, and the other two will be thin. Just follow the two thin wires, which will lead you to a scoket fitted on the circuit board. Upside down the circuit board, and trace the tracks of these wires, and you will reach to the vertical output section.
Normally Toshiba uses a 7 pin IC, number [TDA 8403K], in this section, the number may vary according to sets model, but the function will be the same for all. It will be screwed onto a metal hetsink. I advice you to resolder all the soldering ponts of that IC, by applying a little more solder, without making any solder bridges between the terminals. Normally this may resolve your problem, as there is a chance to get soldering loose in this section.
If this does not help, resolder the IC out, and go for a same type and number, replace it.
