Question about Panasonic CT25G7 25" TV
Over the last few weeks my TV has come on with either no problem at all or a thin bright line across the middle. (Left to right) If we hit the set from the sides it would correct most of the time. I know it is a vertical deflection problem from other web sites but what component should i be looking at for re-soulder or replacment. I pulled the circuit board and poked around and found nothing obvious or repeatable. Read that it may be a cold solder or bad cap but any clues where to start looking? Flexed the circuit board a little as well and nothing repeatable. Thanks
I also suspect its just bad solder connections, the vert. o/p ic is maked ic451 look for all the ic's on heatsinks. it should have 10 to 15 pin all in a straight line & be attached to a small heatsink. if i remember right i think if you are looking at the tv from the back it is on the left side near the front (by the buttons/swtitches). resolder all the pins on the ic & resolder the parts just around the ic as they too also develop bad solder connections. just remember to check for shorted pins after soldering. good luck.

It seems to me that your set have dry joints, resolder arround the vertical section especially the vertical IC. Also check the horizontal section for dry joints. If your're not a technician seek professional help.
