Picture tube is weak. You can add a booster the Picture tube. I would replace the set.

I have a SYLVANIA LC195SL9A flat screen TV that has suddenly lost picture; audio comes through fine.


This is a fairly old model flat screen. I would venture a guess that the back light circuit bit the dust. Try the "flashlight test". With the set on, and tuned to a channel that you know has reception, shine a flashlight at the screen at various angles and look to see if you can see a very faint picture image on the screen. If so, the back light is gone. As old as your set is, I would recommend a new one rather than repairs.

I have a Sylvania 6427 17


It sounds that the width of the picture to your TV is more than normal. There are two reasons for this fault. If the width adjustment data value in its service menu mode has been misaligned or the output DC voltage from the main power regulator is more than normal. You can determine which among the condition stated above is now effected to your TV
Just look at the picture. If the width and height of the picture is seem to be more than normal, make sure that the power regualtor section circuit has the fault. If the dimension of the picture is affected to its width only, [excess than normal] the data value with service mode should be checked.
Also note the position of the picture. If the picture position has moved so much than normal, ether towards left in this case, you have to adjust the picture position. Anyway, it will be best to contact any experienced service technician, since, service mode entry and data adjustment are skilled work.

Sylvania 27 in tv picture


It sounds like your vertical has shrunk, causing the picture to look squashed. Most likely a bad component in the vertical output stage.
