TTE Overseas Support Department 4.Alignment Procedure Ⅰ. Summarize M70 is a chassis based on TB1238AN and SDA55XX. In trial run, burn the latest software to SDA5555 which has a 128KByte flash memory. At least after the first batch production, make the mask, please take care in production.
Check the voltage across C835, it should match the below table or check the mains supply building block. Model Mains supply (V) 14DN2NYD 44-140FLP-IR1A 108±3 2. AFT adjustment: Cut off the RF signal and input a 45.75MHz (for NTSC set) color bar signal to the IF pin of tuner (pin11).

Enter Factory mode,press “CC” button to stop vertical scan. (Note:RCUT/GCUT/BCUT should be preset to 80,and GDRV/BDRV to 40) 2) Adjust the SCRREEN potentiometer (nether one) on the line output transformer to make a horizontal shining line just visible on the screen.
