It sounds that the width of the picture to your TV is more than normal. There are two reasons for this fault. If the width adjustment data value in its service menu mode has been misaligned or the output DC voltage from the main power regulator is more than normal. You can determine which among the condition stated above is now effected to your TV Just look at the picture. If the width and height of the picture is seem to be more than normal, make sure that the power regualtor section circuit has the fault. If the dimension of the picture is affected to its width only, [excess than normal] the data value with service mode should be checked. Also note the position of the picture. If the picture position has moved so much than normal, ether towards left in this case, you have to adjust the picture position. Anyway, it will be best to contact any experienced service technician, since, service mode entry and data adjustment are skilled work.
Hello, I need some more details so I can help, whether the image has grown in height or width? Or that the picture has grown at once, even height and width together? In addition I need the TV model, it says on the sticker at the back of the TV.
One of the following may be misaligned.
i) Aspect ratio of your TV may be wrongly selected. i.e. select 4:3 in place of 16:9 or vice versa with your Remote .
ii) Picture Width or Height may be wrongly adjusted. With the help of Remote, select MENU go to PICTURE option, reduce height or width which ever is needed.
Have a nice day
Rating the solution is highly appreciated.
There is a service menu adjustment. I have seen several of these sets with bad components in the horizontal width control circuit. maybe your other set has a width problem. put both on the same channel. like cnn with the ticker on the bottom. what is the difference in size? the width adj. procedure is: with the set off. use the remote, enter. MENU>5>VOL+>POWER . the set will come on in the service mode. then with the menu adj. buttons you can step threw the service menu to H.WIDTH adj. until full picture. also VERT. HEIGHT. when you are done adjusting make sure you press the mute button and watch the word WRITE flash from green to red or you won't save your adjustments.
Can't you set/adjust that on menu settings? If not, and no adjustable knob inside for width adjustment. You are now dealing its adjustment with MCU, or its eeprom ic. Check its required power supply it should be within spec. Better to have an schematic if you deals within its electronics parts.
You may be able to adjust the picture width and height if there are
controls. Look at the back of the set for holes labeled V.Size and or
H.Size, these are the Horizontal and Vertical size controls. You'll
need a small screwdriver (3/16) to insert into the control and adjust.
If there are no controls then it may need to be serviced as there are
capacitors that have failed which are causing the picture to change
No my friend, there is a problem with the width circuit, and this would be in the pincussion correction circuit of the TV set. There is alot of high voltage in this circuit, and if you have no TV repair experience, play it safe and call in a tech to service this for you. there is not any adjust ment that will fix this. Good Luck
