I don't think you can buy a vertical circuit for this set . most of parts are mounted on the main board and have to replaced individually.

Our Panasonic model PTH 3778R has elongated its vertical size about 2 inches outside the screen limit. Is there a way of adjusting the vertical size?


Usually this means that a cap in the vertical circuit is starting to fail. Are there any other symptoms at all? Does the height seem stretched more at the top?

No horizontal and vertical deflection available:- audio OK


Check its horizontal output stage circuit. Replace damaged component/s. Vertical output stage gets its working voltage from the horizontal output transformer. If you want to get vertical deflection, this transformer, otherwise known as {LOT] should work to produce the supply voltage to vertical output stage.

My picture will only show the middle 3 to 4 inches


Check the vertical circuit for bad caps or bad soldering.

Line across middle of screen.


The line of color is due to a failure in the vertical circuit. The main suspects are the vertical Ic AN15525A and/or capacitor c308 220uf@35volts
If you have the capacity to do so, you should check the other electrolytic capacitors in the vertical circuit which are USUALLY located near the vertical IC in most cases
you can purchase the part at

Picture shrinks horizontally every few seconds.


You are changing parts in the wrong circuit. The problem is in the vertical circuit. Look for the vertical IC and resolder the pins first. It should be an LA7837 or something similar. Also, check the 100ufd and 47ufd caps in the same circuit.

Keep us posted.

Problem with panasonic tv


It is usually caused by problems from lead solder that sometimes does not connect, so there are some points of the components that are not connected with lead solder to the circuit. if it appears vertical line means from the IC (integrated circuit ) Vertical, you can solder all the points in the IC ( Integrated circuit ).

1 inch lines on top and bottom of screen


Is the picture overall too small by 1 in. on top and bottom? Or is it cut off by the lines?

If it's too small, look for an adjustment labeled Vertical Height. This may only be accessible internally, it's normally a service adjustment, not a user adjustment.

Your problem is a vertical deflection issue, either an adjustment or the vertical circuit requires repair by a technician. In the latter case, electrolytic capacitors are a likely cause.
