First need to check the power supply values as described in the attached service manual.

Next step is risky… :roll:
Obviously, take care when using the service menu as you can reset everything!

Enter in the service mode to verify the values for the vertical amplitude. See more details on page 13 of the SM.

1. Service-1 mode is entered by pressing the:
STAND-BY→ DISPLAY→ MENU→ MUTE→POWER ON

2. Access the Adjustment Mode by pressing the “VOLUME” keys ( Up or Down)

3. In the Adjustment Mode, use the DOWN or UP key get to the 'VA' , cycle thru all selection sequences (for the all system) step by step:
AGC>SCT>SBT>BLR>BLB>RG>GG>BG>VSL>VS>VA>HS>SC>CDL>STT>AKB>PDL>NDL>PSR>NSR>OL>LCO>TXP>MVOL>FMWS>AGCS>OMD>SCL>PWL>AGN>PEK>ACL>FCO>SCBT>SSP>PSNS

4, When you reach to the VA section, select by pressing the CHANNEL keys (Up or Down)

5. For the VA section activated, check the adjustment values. You may use the VOLUME keys to increase or to decrease the VA adjustment values

6. To store the new values in the non-volatile memory you need to Cancel the Adjustment Mode by re-pressing “Power OFF” key.

You may need to repeat those steps (1 to 6) many times in order to get the correct values for the vertical amplitude adjustments.
