Adjust PP1 for 140V +/- 0.5V across CP37.
If the memory NVM (ICR3) is replaced, it is essential to carry out all the adjustments required in service mode because the replacement memory is supplied NOT pre-programmed. If the EPROM (ICR2) containing the software is replaced, compatibility with the existing NVM is verified automatically and if necessary it is initialised. These operations may take some time, so you must wait until they are completed.
Although the individual settings can be accessed and memorised individually and independently, it is advisable to carry them out in the sequence in which they appear when pressing the P- key.
The correct value to be set for each appliance is marked on the label on the back of each item alongside the writing Option byte. The value can be entered using the number keys on the remote control.
Connect a generator (or a known transmitter of reliable quality) to the antenna input and use the remote control number keys to enter the value of its RF frequency (which must be within the frequency band indicated by the menu), then press OK. The setting will be made automatically. Repeat the procedure for BG, L and L’ standards. If any of the settings are omitted, operation, automatic search and tuning in this standard may be incorrect.
Connect a generator with an RF level of 1 mV (60 dBmV) (or a known transmitter of reliable quality) to the antenna input and use the remote control number keys to enter the value of its frequency (which must be within the frequency band indicated by the menu), then press OK. The setting will be made automatically.
Adjust the potentiometer G2 on the transformer EHT until the confirmation message appears. No particular signal set-up is required.
The VS (Vertical Slope) function must be adjusted in such a way that the central horizontal line in the test signal is exactly on the border between the visible image and the lower black part. It must not subsequently be altered.
Now set the remaining parameters as accurately as possible in the sequence in which they appear.
Adjust as accurately as possible in the sequence in which they appear.
Using a B/W bar signal, adjust to obtain a grey image. The blue setting is fixed.
Once you have made the necessary adjustments, press the OK key on the remote control in one of the menus in which it is active to memorise all the functions and return to normal operation of the appliance.
