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?

    To say the problem is generic is not answering my query.

  • mgoldstone May 09, 2008

    Actually it seems stretched more at the bottom, and I don't see any other noteworthy symtoms.

  • mgoldstone May 10, 2008

    I'm still awaiting a reply, but I presume your thought is that a major home or service center visit is necessary to test out the vertical circuit, and that you don't think I as a mildly informed layman can fix it?

    Hi, I'm awaiting Abrsvcs' response - he planned to look up the part number and circuit designation, and I had asked him whether I as a mildly informed layman should avoid tackling this.

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?

    Thanks for the update. I'll look up the specific model tonite and post more details. The problem is with a 100ufd cap in the circuit having a smaller value around 5ufd or so. I'll look up the part number and circuit designation for you. If you need to have this repaired by a service shop, the parts should not cost more than about $5-$10. Add in the local labor rate for the total cost.

    Stay tuned.

    Update: My Panasonic service info site has been down. It should be available later today. Sorry about the delay.

    Stay tuned...

I have a Philips TV model: 27pt9015d. at the top of the screen several horizontal lines have appeared. it looks like the top inch is being cut off and then flipped back. that is - when credits are...

sounds like the vertical adjustment has spanned beyond the screen, causing it to jump up and then upside down. after the cover is removed look for vertical adjustment and with a non-conductive screwdriver, adjust it a little bit either way to see if it fixes it, if it doesn't fix it, then look again for the right one.

Sony 43 inch rear projection tv, I have lined up the convergence but still seeing red and green around edge of the tv on the images, seems fine in the middle of the screen though.

Always start at the vary center of the screen with Green. Position Red over Green, then Blue over what now will look yellow. If all is perfect except the outside, you will need to adjust "Mid-Size" until the middle is just as far off as the outside lines. Then adjust the main "Size" adustments to match. Go very slow or you can make a mess of it.

Panasonic PT-47X54

This is the vertical problem,it is a bad capacitor you must replaced all electrolytic capacitor in vertical section and resolder all associated parts there,so it works better again.

Hope it will helps you;

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.
