Question about Standard (CRT) Televisions
No remote control and the kids have managed to change the picture size. Is there a way to change the picture back to 16:9 by using just the buttons on the set itself?
On the inside of the TV, on the flyback transformer there should be two controls. Turn the one that says "screen" very slowly clockwise while looking at the pix. The pix should get brighter as you turn it up- if you go to far you will see lines in the pix or the TV may shutdown.

"i already paid for the tv so why pay for something that should be readely available to me in the first place I should have access to all the features on the tv ".. WRONG!!!!!!!!!You should have a warranty for this TV but it's old , anyway. First,receive a reference image (let's say CNN).Second:press "Sleep Timer" key and set the value to "0". Then press "Display" and "Video Status" keys at the same time. Third: use "Vol +/-" and " Channel +/-" to select "2.DEF(D)".Go to "D03: V.SIZE" and modify step by step the value for best fitting. There is also switch " SW401" on the main board for centering the image . Finally, press "EXIT" key till you exit the "Service Menu". Don't try to modify anything else!!!!!!!!!!!!!!!!!

Hello, I think you have a faulty "horizontal width" or horizontal
linearity preset pot. This pot will be located on the main PCB
and you can adjust it with a small screw driver, when you do the
picture will shift from left to right or vice versa, or move back to fill each side. If it wont hold after making the adjustments then the pots ( potentiometers) need replacing, which means unsoldering them from the printed circuit board( PCB) and take them in to your local radio shop for new ones. By the way you might need 2 pots ( 1 for the WIDTH and 1 for the LINEARITY)

I have the AV-27S33 model and in the rear to the right of the inputs are two slits and inside these slits are two screws. The top screw is the focus,the bottom the brightness.Your tv is a different model but it may have this same adjustment,if it does try turning the bottom screw to the right to increase the brightness.
