1. Do not install, remove, or handle the picture tube in' away from the body while handing
2. When service is required, an isolation transformer should be inserted between power line and the receiver before any service is performed on the chas-
3 When replacing the chassis in the cabinet ensure all the protective devices are put back in place, such as barriers non-metallic knobs adjustment or compartment covers or shields, isolation resistors/capacitors,
4. When service is required, observe the original lead dressing. Extra precaution should be taken to assure area. Particularly note the R. G. B. lead dressing. Ensure they are dressed well away from the horizontal scan and F. B. T. circuitry.
5. Always use the manufacturer's replacement component. Always replace original spacers and mintain lead lengths. Especially critical components are indicated thus A on the parts list and should not be re-
place those components that indicate evidence of overheating.
6. Before returning a serviced receiver to the cusoperate without danger of electrical shock and he sure that no protective device built into the instrument by the manufacturer has become defective, or inadvertently damaged during servicing. Therefore, the following checks are recommended for the continued protection of the customers and service technicians.

Insulation resistance should not be less than 7MO at 500V DC between the mains poles and any accessible metal parts. Also, no flashover or breakdown should

TUBES. The primary source of X-radiation in this receiver is the picture tube. The tube utilised for the above mentioned function in this chassis is specially constructed to limit X-radiation For continued X-radiation protection, replace tube with

the same type as the original HITACHI approved type PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in HITACHI television receivers have special safety telated characteristics. These characteristics are often not evident from visual inspection, nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety chatacteristics are identified by marking with a A on the schematics and replacement parts list in this Service nent which does not have the same safety characteristics as the HITACHI recommended teplacement one. Product Safety is continuously under review, and new information, always consult the current HITACHI Service Manual, A subscription to or additional copies of HITACHI Service Manuals, may be obtained at a nominal charge from your HITACHI SALES OFFICES TUBE DISCHARGE

IC201 allows bi-directional communication between the SECAM decoder IC502 and automatic system manager for SECAM identification. It delivers the VCXO (voltage controlled xtal osillator ) reference frequency (1 (3)MHz only) to the SECAM decoder via pin 32 of IC201. Once SECAM is identified, the gated reference signal is outputted to pin 32 of IC201

The inputs at pins 14 and 16 are clamped then fed via a buffer stage to internal delay lines, which are driven by a clock signal of 3MHz to obtain a delay period of 641 Seconds. This internal clock is generated from a 6MHz voltage controlled oscillator, and line locked by the sandcastle pulse input at pin 5. Low pass filters af-The undelayed and the delayed signals are then added. with the resulting R-v and B-v signals being output These supports are then fed to IC201 at pins 28 and 29

Remote Control and Tuning Circuitry:

The remote control receiving unit CP1201.contains an infrared amplifier and powered by the +5V supply. which is stabilized by 2D1101. The output from nin 9 of this unit is applied to pin 16 of IC1101.

This 1C type M37210M4, performs channel selection. UP/DOWN analogue control, an screen display, search tuning, and controls inputs and search tuning, and controls inputs and outputs to and from the AV terminal. IC1102 is the memory IC, which stores the data relating to the above functions, then transfers that information to IC1101 when required. Both these 1Cs are powered by the +5V supply. X1101 supplies IC1101 with a basic clock frequency which controls all operation a basic clock nego

When the TV is first switched on IC1101 must be initially reset, and this is achieved by IC1101 stage. As the +5V supply begins to rise from switch on pin 3 of oll 05 in held "Low" This is applied to pin 30 of IC1101 thus resetting the 1C. Once pin 1 of Q1105 has almost reached its + 5V potential, the "Low" is removed from nin 3 thus releasing the reset condition. When the search routine has been initiated and a signal has been located pin 14 of IC201 will become "High". This is applied to pin 34 of IC1101, and informs the IC that a signal is present. The search routine then stops,

and the IC will monitor the AFC signal present at pin

Pins 46 and 47 control the signal system. Contrast, colour, brightness, sharpness, tint, and volume are all controlled from the remote control handset (the volume can also be adjusted by + and - buttons on the front of the TV), and will produce DC level changes from pins 3~8 of IC1101. which are then fed to the relevant pins of IC201.

Pins 31~32.37~39 and 11 from the in and out ma-

Ding 12 and 13 are the clock and data output Dins. These signals are supplied to the memory IC1102. It is supplied to pin 16 of IC201. When "High", the IC will process external inputs applied to pins 6 and 15. and when "Low", the internal signals are processed.

The handset button marked TV/VIDEO will need to be pressed. This will then produce the required "High"

L1102, C1102, and C1103, on pins 28 and 29, determine the display oscillator frequency. The horizontal and vertical inputs at pins 1 and 2 determine the actual position of the on screen display. When a command requiring an on-screen display is received by IC1101.a

This is applied to pin 21 of IC201, and blanks out a nortion of the picture. The on-screen display informastar is then incontrol into this portion, thus resulting in a

clear display. When the ALARM mode has been set. and the time input has elapsed, an output is obtained

This is then applied via R1184.R1119.C1111.R1118 etc. to pin 5 of IC4501 thus causing a "Bleen"sound to be heard

Once the "OFF" timer mode has been set, and the time input has clapsed, pins 21 and 22 of IC1101 output a

This removes the supply to the base of O954 and as a result the +9V output of O953 disappears. This places

the TV into its standby mode of operation by removing E. H. T. generation as explained previously.

When the "ON" time has been estimated and set, the standby command must be transmitted by the handset. to place the TV into its standby mode. As an indication that the standby mode is only remporary, pin 36 of IC1101 is taken "High" and "Low" alternately, caus

When the entered time has elapsed, the "Low" outputs from pins 21 and 22 of IC1101 are removed and the TV will return to normal operation.
