Question about Televison & Video

Open Question

No picture I have a 2003 symphonic wf2703 that was operating with a full picture but had a few horizontal lines through the top of the screen. Now there is no picture at all just a black screen with a single line through the center, horizontally. Any suggestions? Hi !!! I have the same problem, you wouldn't happen to know the location on the board of the chip or possible part number that would be printed on that chip would you ? Not sure which is the vertical I.C.. Thanx Wayne McEathron Gouverneur, NY 13642

SOURCE: Thin white horizontal line center of screen!

The set should have a vertical output IC,You need to change it ,maybe you can check the B+ going to it because it might have opened the safety resistor if the IC went bad.You can check for broken board too unless the set is never move from one place.Be carefull when checking voltages ,there is still high voltage,not much but can num your whole hand.

My 2003 Symphonic model WF2703 television suddenly will not turn on. Is there a fix for this? Thank you


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Symphonic WF 2702 has sound but no picture. The


This could be a capacitor if your lucky but can also be the horizontal transistor. The repair could cost you between 60$ and 150$
My opinion; it's not worth it.
