Does anybody either have this service manual online or the service codes for this model. This TV currently is transmitting the picture past the left and right edges of the tv. Verticle is fine but horisnontal is to big. Otherwise the TV works fine. I inspect the area under the shield for poor solder connections they all seem good. Model F27450TX1 chassis ATC113BB1.

to enter the service menu, do the following------press and (HOLD)the (menu) and (power) buttons at the same time. then while holding buttons, press the (VOL+) button. then release the buttons, and the menu should be on. two digits will appear on left and right sides of screen. press (VOL+) button to advance to #76 on right side screen.(NOW BEFORE YOU START, WRITE DOWN THE SETTINGS THAT ARE SHOWING NOW, BEFORE YOU TRY TO ADJUST ANYTHING) then scroll to horizontal width, and adjust to desired width.(BE VERY CAREFUL, ONLY ADJUST TO PROPER WIDTH. IF YOU CAN'T GET IT RIGHT, STOP AND RETURN IT TO PREVIOUS SETTING) if you go to far you will make tv shut down, and will cause a lot more work to get it going again. good luck.

Which P value is horizontal width. You have 1 through 47 and they don't correspond with the values on older sets.

i don't know which one is horizontal adjustment, but you could try each one a little until you find it. you can tell which one by changing the setting a little at a time. but make sure you write down settings first, so you can return them back if needed.

before you change the service menu onthat set you might want to look at the pin cushion diode and pin cap underneath for cold solder joint

see if this uploads but if not its 21
