Need to center the picture

I need to center the picture on the screen. The picture has moved up on the screen. The bottom of the picture is cut off and in the HD mode there is a line on the top with the bottom of the picture above the line. Is there some adjustment that can be done to center the picture?

Re: Need to center the picture

This is a defect in the vertical scan amplifier. It is not an adjustment. Most of the time there are a number of capacitors in the vertical deflection amplifier that can cause this type of fault. Sometimes the output drive IC can cause this fault, but more rarely.

An experienced service tech can locate the defective parts and replace them. The average time involved is about 1 to 1.5 hours.

Ilo tv has green tint picture its not hd just regular digital i think problem was caused by a huge speaker i sat near tv

I have done this before. The speaker caused your green tint. The only way I was able to fix mine was with a magnet. I was able to get the green to the bottom corner of the screen. But be fair warned using a magnet can also make it worse to. The best thing to do is bring it to a repair shop and have them fix it for you.

Can't read stuff at bottom of screen

it is possible the picture format is set to stretched. look for a button on the remote that can do this. it could also be the signal. try looking at a different channel that has lettering along the top and bottom and determine if the entire picture looks like it needs to be moved up. if after all this you can still determine that the picture is misaligned post the model number and i can help you move it up.

Picture not fitting on screen

Unfortunately, this is an internal adjustment that can not be done by you without voiding the warranty. Call the store and request warranty service. You should not have to pay to get this resolved.

User Manual OR how to adjust the picture settings...Picture on TV is Cut Off

Normallly, if the picture size button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made.
For example:
A Motorola Cable box needs to be set up to go to a wide screen or zoom when an analog signal is detected.
Some Dish Network boxes have Size buttons on their remotes and also in their main menu.
It's difficult to determine the repair without knowing the types of the peripherals.
Hope this helps.

Bottom of picture is cut off

Usually when the vertical starts shrinking slowly, it is due to capicators getting out of tolerance in the vertical output section of the chassis. If it can be adjusted out through a service menu, you'll probably need a tech with the right equipment to perform it.
