I am proud of you. In the future, I benefited from your services.
;
I found this manual to be complete in every detail. Besides the schematic it has a complete set of alignment instructions which are easy to understand. It also includes a complete parts list as well as an explanation of how the power supply and safety shutdown circuits operate. Even a schematic of the tuner is included.
 ;
The product was good and just what I needed, however I had moderate difficulty with the down load because the sight would not recognize my pass word. I was finally given a direct link to the manual and that worked.
;
Very quick and easy website to use and fast download of manual, quality of manual is excellent and will be pleased to use this service again in the future, thanks so much!

DESCRIPTION OF SCHEMATIC DIAGRAM
SAFETY NOTES:
1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE REPLACING PARTS. 2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING.
NOTES:
1. The unit of resistance �ohm� is omitted. (K = 1000 ohms, M = Meg ohm). 2. All resistors are 1/16 watt, unless otherwise noted. 3. All capacitors are µF, unless otherwise noted. (P = µµF).
VOLTAGE MEASUREMENT CONDITIONS: IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH �å� ( ) ARE IMPORTANT FOR MAINTAINING THE SAFETY OF THE SET. BE SURE TO REPLACE THESE PARTS WITH SPECIFIED ONES FOR MAINTAINING THE SAFETY AND PERFORMANCE OF THE SET. 1. Voltage in parenthesis measured with no Signal. 2. Voltages without parenthesis measured with PAL Colour-Signal. 3. All the voltages in each point are measured high impedance voltmeter.
WAVEFORM MEASUREMENT CONDITIONS: SERVICE PRECAUTION:
THE AREA ENCLOSED BY THIS LINE ( ) IS DIRECTLY CONNECTED WITH AC MAINS VOLTAGE. WHEN SERVICING THE AREA, CONNECT AN ISOLATING TRANSFORMER BETWEEN TV RECEIVER AND AC LINE TO ELIMINATE HAZARD OF ELECTRIC SHOCK. 1. Colour bar generator signal of 1.8V peak to peak applied at Base of Video Buffer Amp. Q203. 2. Approximately 4.0 V AGC bias.
