Question about Panasonic CT-27SF25 27" TV
Had a problem with the vertical settings and used advice from website to get into service mode but information incorrect to exit service mode. Have pressed exit twice, turned it off for a while, and even left it unplugged overnight and no results. Tried to go back into the settings but no results. When I turn the power off with the remote it goes into the next servicemenu item and the tv has to be turned off manually.
PANASONIC: Panasonic TV's after 1996 can be set to "Serviceman Mode" with the following remote control sequence: First, select the SET-UP icon and select CABLE mode. Then, select the TIMER icon and set the SLEEP timer for 30 minutes. Next, press the ACTION button twice to get out of the menus. Now, change to channel 124. Then, adjust the volume to minimum (0). You're almost there - Hit the VOL down button on the TV itself (not on the remote) and a red "CHK" should appear in the upper corner. Now, if you press the ACTION and VOLUME DOWN buttons (again, on the TV, not the remote) you will toggle between AGING and SERVICEMAN modes. Select Serviceman mode. The POWER button on the remote control will select one of the five Serviceman Adjustment modes. The modes are: B - Serviceman VCJ SUB Adjustments. These include sub-tint, sub-color, sub-brightness, sub-contrast, colorkiller/ABL/gamma,audio and video adjustment, and vertical size. C - Serviceman VCJ Cut-off adjustments. These include Red, Green and Blue cut-off, red and blue drive, automatic fine tuning(AFT), RF AGC (RF gain control), horizontal center, beam limit,etc. S - Serviceman Options Adjustments. These involce the PIP and clock. M - Serviceman MTS (Stereo/SAP) adjustments. CHK - the mode you first entered. Normal picture and sound, lets you check things over and still have a hotkey into the service menu. There is one more adjustment that isn't in the five modes, it's global. When in either the yellow or red CHK mode, you can press RECALL on the remote control to enter the purity firld check mode. This lets you select a pure white, red, green, or blue screen. A good thing to walk away from if you just want to temporarily freak out the floor manager, but it will be fixed as soon as the TV is turned off. To get out of Serviceman mode, press ACTION and POWER on the remote simultaneously for at least 2 seconds. The TV will momentarily shut off and then comes back on. If this does not help you will most likely need to get the service manual as you should always have that anyway before ever attempting any serve mode adustments. Also do not forget to ALWAYS write down all of the values that you change incase a problem arises. Good Luck
