Try with ok and ok from the tv set and remocon
or also try menu and menu
but to inform you this works with specific suffix for your tv
hope that was helpful

If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic /Timeslide, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.

go to service menu . com and get service menu codes when your in the service menu change from inst. tv to standard dont mess with anything else you could dammage set

1. press the menu/set button on component to select display mode
2. use the +/- button to set the time mode (AM 12:00 blinks)
3. press the menu/set button for at least 2 seconds (the hour will start blinking)
4. Use the +/- button to set the hour, must roll the hour to change am/pm
5. press the menu/set button to switch to minutes
6. use the +/- button to set minutes
7. press the menu/set button to finish setting the time

So if the picture is short at the top and the bottom you can first try the service menu and adjust the vertical size and the vertical center. You must be very carefull when adjusting this service menu as a small mistake can make a minor adjusment become a very costly repair. Do not attempt this if you do not think you can figure it out and always always write down the values of the adjustment before you try them.Ok Heres goes. To enter service mode, push and hold the [Menu] button on the set. While holding, push and release the [Power] button, then the [Vol +] button. You will now have some information on the screen: "P0 V0" To actually be able to change these values, you must push [Vol +] on the remote so the information reads V76. Then pushing on the Channel +/- will change the "P" value. P1 - 3 are error codes. If there is a problem with the set that can be self-diagnosed, the "V" will report the code. These codes are available in the RCA repair manual.Go here to get the chart as it will not fit in this post. You really should invest in a service manual as all the info you will need will be in this manual for your set. Good Luck.
