Re: picture zooms in and out

Your set might have a regulation problem, what that means is all the voltages are going up and down and not esteady,the 130 volts source can go as high as 150 and as low as 110 volts DC and this is only one of all the sources,this can happen when you have a loose conection in the primary side of the switch mode power supply or a feedback problem witch keeps the power supply regulated and steady,If you are familiar with tv service this will give you a place to start but if you are not too familiar be safe and call for assistance from a servicer.

Top and bottom of screen are cut off how do we adjust to get screen to fit

Press the "Aspect" button on the remote until the picture looks appropriate. You are probably trying to display a 4:3 ratio channel on your 16:9 ratio TV. You are probably viewing it in "zoom" mode, which does not stretch the 4:3 ratio video, but enlarges it until it fits the width of the screen, which zooms part of the video off the top and bottom of the screen.

Look for button on remote labeled size,aspect ,format or zoom. You can change the picture size to your liking. Different channels are broadcast in diffrent formats.

Picture format to large

There should be a format button on your remote to change between widescreen & fullscreen as well as the zooms. May say format or aspect. If not on remote look through your menus. Make sure which ever u select u do not choose a zoom. This will cut of top & bottom of picture

My tv zooms in and changes the format.

This is normal - you are zooming in on the picture. Most people use the zoom feature to "stretch" a widescreen movie so it will fit the screen.

Panasonic pt-61sx60a zooms in

hi this as a problem with your convergence ic they will need replacing this is a common fault with these types of tv nearly every problem on this site is the same as yours eventually your telly will stop working all together but if this happens you will then need to replace some resistors as well as these tend to go with the convergence ics so this will also need to be checked if you are unable to do this repair yourself then the cheapest way is to take the telly to repair shop yourself as calling someone out will charge call out and will also charge for transporting witch can ad 75 pound onto the price of repair.
It is very common problem so the repair shop should have no problem sourcing parts for you best thing to do is shop around and get the best price you can tell them what the problem is and this will stop them charging for finding the fault just say someone looked at it for you and told you what needed repairing as sometimes they will try confusing you with unecasarry repairs let me know if you can do the repair yourself but only if you have correct equipment to test all parts needed hope this is some help to you
