Question about Televison & Video
I have a Sylvania SRT2227S 27" television. I got the TV from a friend. When I plugged it in, there appeared to be nothing wrong, until I started changing channels. I noticed something strange, there were thin white lines across the top of the screen. But this didn't occur on all channels. It only appears on programs and commercials where the picture goes within an inch from the very top of the screen. It also occurs, when I change channels, the panel that displays the channel number, and name of the program appears to 'roll over' and appear upside down again on the top of the screen. This is very strange and I have never seen or heard of this happening before. I have no clue as to what is going on.
Check and replace all the electrolytic capacitors at its vertical output section. The lines you refer here are technically called, vertical retrace lines, and are mainly due to capacitors itself. Check all the solder terminals of vertical output IC for any loose solder terminals. Resolder all the suspected solder terminals by applying a little more solder to each point. When replacing capacitors stated above, replace them all at one time. There will be 5 of 6 numbers of them, the most, and wont cost more. If you wish to get more details, surf the following link. There are over two thousand and four hundred posts. All are related to television and other domestic electronic equipment service help. You can get a solution there. Type in the brand name to your device to its search box, can be located at the top right of the display window. It will make search easy.

Hi Tammy, Yes it can be repaired, most companies charge about $250.00 to repair the convergence circuit. Have them check to see if the SRS/WOW 3D pcb has been modified also!
