Toshiba 24af45 horizontal
If rolling in a right to left and not up down it is a sync problem--horizontal sync comes from one of two places in general---a pulse off the high voltage transformer or directly off of what is called in the trade the Jungle IC.That is not a joke--Most of these sets use a large IC (63 pins or more not unusual) that contains: color, video, vertical drive, ABL and much more---so much is crammed into that chip it decades ago was named the Jungle for clear reasons.A schematic and or scope may be needed to trace and find what is bad.if off the high voltage transformer (more common in old sets than new ones) it will be a open resistor.If at the jungle you would have to go to the pin with the sync and follow it out to see if none at source or if lost somewhere down the stream.
You need the original remote controller to be able to switch input modes.Universal ones usually don't work. If you don't have the original remote and can't find it ever or if it is too expensive you can buy an rf modulator ( very cheap) and connect your dvd player, game console etc) to the modulator then connect the modulator to your antenna with a coax cable. This worked for me. It placed the connection to channel 4 and other cable channels are still working,
You can buy the RF Modulator from: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180299245670

Toshiba 24" TV Problem
Neither adjustable nor the picture going bad.
But appears to be a minor problem, chances are that a component in the vertical section of the TV is starting to fail. If you would opt to check it out/fix yourself, most probably would be a capacitor very near the vertical IC, value would be something like 100uF/50V. Though considered a simple job, this would require that you be familiar with electronic components & circuitry, a bit of soldering and use of a DVM.
Should you not be comfortable doing the above, perhaps your best bet would be to seek the services of a qualified tech.
Hope this be of some help/idea. Post back how things turned up or should you need additional information.
Good luck and kind regards.

Toshiba 65H83 is flickering after maybe an hour on. Is this a convergence chip issue?
Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the brand name of your set, in its search bar at the right side column, and press enter. See it in Webview by mobile. Mobile View has no search box.
