    I have the exact same problem. It all started with a "fuzzy" line at the bottom of the screen but when I turned the set on yesterday, all that appeared is a shrunken screen. The total picture is about 2-3 inches tall. Please help! If I don't respond on line then please send any information to [email protected] thanks in advance.

TV Picture shrinks down more and more until it gets to a line.


You may have a cold solder joint around the Vertical circuit. Resolder the pins of the LA7833 IC and the components around the IC.
Check the C308 220uf/35V & C320 100uf/50V.

Tv keeps flat lining and shrinking picture


If this is a crt tube tv. Your vertical ic is loosing its connection with the board. Better to quickly resolder it or reflux it with a new lead. Before the IC fail for good.

Picture clear, then "grainy" can hit TV and will clear up


sounds like a cold solder joint in the tuner circuitry. Unless you can do it yourself it's probably not going to be worth the repair bill.

36 Inch Toshiba - Single Bright Horizontal Line


You're losing your horizontal voltage that drives the fly back transformer. Poking around inside can be hazardous to your health since you have to worry about high voltages present on the picture tube even when the TV is off. You may still be able to get parts for those old TV's but they may hard to find. You can try here, but if you have no background in TV repair, it will be pointless.

Hi,

If the shrinkage is just the top & bottom then it is relatively easy/low cost fix. Most probably, a capacitor in the vertical section is nearing end of its life. This would be the biggest of the bunch and would be something like 47uF/50V.

If however, the shrinkage is on all four sides, then it is the master power supply that is at fault. Chances are the main B+ is getting low which cold be caused by the big filter capacitor or an erratic regulator. This is not a simple fix and would require the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
