Question about Televison & Video

Folded picture TV is a little over one year old and the picture has "folded" over on top of itself. About the top 3-4 inches is upside down. Is this a capacitor that has gone bad or is there a bigger issue? Model #27PT5445/37

The primary suspect here is a defective capacitor at the horizontal deflection circuit. You can also try flexing the board while the tv is on, and try to observe if the problem would disappear even for a second. just to check for any loose solder that usually occurs in a television. !!!Word of caution, !!! The inside of a live TV has several high voltage points that can easily do harm. If you are not comforatable working with such conditions, I suggest to have the unit serviced by a qualified technician.

You have a vertical deflection problem and the parts location of the bad ones are C2465 10mfd at 160v and shorted diode at location D6460 part #9340 549 45115 Call Tritronics at 1-800-638-3328. I think they sell to consumers. Parts must be unsolderd and new soldered back in.

For how many years this TV with you? Most tv now a days after few years of using vertical IC solder started to dry(dry solder) you can try to re-solder or you may check also two capacitors (100uF/35V) for most JVC model has this symptom with this parts changes its electrical characteristics. If still problem persist replace vertical IC. Hope his helps, Good Luck

Elongated picture

There is a bad capacitor in the vertical circuit. If you feel comfortable working inside a set and can solder, update this and I'll try to get the specifics for you.

TV Picture Reduced to Line across the Middle

This is called field-collapse. Either

1. The problem lies in the vertical deflection voltage-doubler circuit. The usual fault is a single capacitor of 100uF/35V that has failed. It is normally connected to a rectifier diode right at the vertical IC. Replacing the capacitor usually gets it working perfectly again.


2. The vertical drive IC has failed.

If you are finicky around technical work, then a reputable local repair shop in your locality should do it quickly for you and charge only labour.

Sony 27" picture quality

You probably have a leaky or open electrolytic capacitor in the vertical circuit. This will require troubleshooting by a repair specialist, unless you can obtain a diagram and do a little spy work with an oscilloscope

Horizontal line in my TV.

"Guest" obviously has no idea what he is talking about. There is no such thing as "frame section" and if the vertical IC, ramp generator or vertical hold circuits were bad, you would have no vertical at all. If you mean that there are thin white lines at the top 3 inches of the picture, and the top of the picture seems folded back on itself, it means that the pump-up capacitor is going bad in the vertical output circuit. This is a very easy thing to correct but should be done by a qualified tech.
