Question about Toshiba 32A50 32" TV
Need to resolder vertical ic part# La7833s
It can either be held in with screws on the bottom of the set, or in the set itself. It could also be held in with the plastic of the chassis that has clips on the bottom. You would usually pull the chassis and remove it from the holes. They are kinda L shaped. Be careful not to yank any wires. I would discharge the tube and unhook the neck board and the anode cup to make sure you don't yank those. Please use extreme caution when discharging a tube.

To ask those questions indicates a lack of knowledge in a very specialized area. This is not really a DIY. Soldering is a skill, especially in an object that has fine tracks. Spill excess solder on the tracks and you will short out the whole unit. Overheat a component with a soldering iron and it will kill it. There is also the Radiation risk at the rear of the TV as well as High tension. You need to know how to ground the unit when opening it to prevent electric shock of a lethal type.
I suggest you call a professional in to do this or take it to a local repair shop. This also involves unsoldering an IC Chip and replacing it. There are numerous money saving DIY's on here all thinking they can do it cheaper and just as well as a trained repair tech. Some actually get in and do the job, but 96% are back in a week or so with either the same problem or greater problems than before.
You have to know WHY those things occurred, they may have been set off by some other part failing somewhere up the line. and technicians know where to look and have the equipment to test the integrity of the whole system as well as generating a test pattern to align the convergence and color wheels. Take my advice for what your life and health may be worth, take it to a repair man and have it done properly

Check the deflection yoke connection cable for any loose contact at its connection socket at main board side. Unplug the connector out from the socket, and re-plug it back for at least tow times. Check the solder terminals of all connections to horizontal output. It will be best to re-solder all suspected solder terminals there. [horizontal sweep signals to the deflection yoke is absent now. Only vertical sweep is present now]
