Service Mode

RCA and G.E. (most models after '94): Turn the TV on. Hold down MENU and hit POWER and VOL+. Now you're in the service mode, looking at parameter 0. It will say: P00 V00 Use the VOL+ key to change the value (V number) to 76. This has to be done before you can do anything else; it's sort of a password. Once P00 is set to V76 you can use the Channel + and Clannel - buttons to select from the first 12 parameters. P13 is another password - set to 77 to get higher parameters. Depending on the model, another one a couple of dozen parameters up will require a password of 78. This varies by model but you will know when you have found it because you won't be able to advance past it. The first parameter, P01, is probably the quickest and easiest to work. It is the Horizontal Frequency control. When you select it, the TV will lose horizontal sync. Turn it all the way down or all the way up with VOL- or VOL+ and then get out of setup (if the TV hasn't shut itself off by then) with the power button. Here are the parameter tables: P00 Password (Must set to 76) P14 PLL Tuning P01 Horizontal Frequency P15 4.58 MHz Trap P02 Horizontal Phase P16 Video Level P03 EW DC (Width) P17 FM Level P04 EW Amplitude P18 B+ Trim P05 Vertical DC P19 RF AGC Chan 6 P06 Vertical Size P20 RF AGC Band 1 P07 Red Bias P21 RF AGC Band 2 P08 Green Bias P22 RF AGC Band 3 P09 Blue Bias P23 D-PIP Chroma P10 Red Drive P24 D-PIP tint P11 Green Drive P25 D-PIP bright P12 Blue Drive P26 D-PIP contrast P13 Password (Must set to 77) P27 Factory Tint P28 Password (Must set to 78) P100-156 - Tuner alignment parameters. If you fuck with these, the tuner will have to be aligned by a professional. 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. Oh well. To get out of Serviceman mode, press ACTION and POWER on the remote cimultaneously for at least 2 seconds. The TV will momentarily shut off and then comes back on.
