Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.

Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!

Good quality. Quick service. I recommend to everyone.
If available, measure current using an accurate leakage current tester. Any reading of 0.35mA or more is excessive and indicates a potential shock hazard which must be corrected before returning the receiver to owner. If a reliable leakage current tester is not available, this allernate method of measurement should be used. Using two clip leads, connect a 1500 Ohm, 10 watt resistor paralleled by a 0.15MF capacitor in series with a known earth ground, such as a water pipe or conduit and the metal part to be checked. Use a VTVM or VOM with 1000 Ohms per Volt, or higher, sensitivity to measure this AC voltage drop across the resistor,. Any reading of 0.35 volt RMS of more is excessive and indicates potential shock hazard which must be corrected before returning he receiver to the owner.
ALIGNMENT PROCEDURES PLEASE READ BEFORE ATTEMPTING SERVICE
1. Use an Isolation Transformer when performing any service on this chassis. 2. Never disconnect any leads while receiver is in operation. 3. Disconnect all power before attempting an repairs. 4. Do not short any position of the circuit while the power is on. 5. For safety reasons, replacing any components should be according with identical replacement parts (SEE PARTS LIST). 6. Before testing, warm up the TV for at least 30 minutes and demagnetize the CRT with an external degaussing coil. 7. When removing a PCB or related component, after unfastening or changing a wire, be sure to put the wire back in its original position. 8. Inferior silicon grease can damage IC�s and transistors. When replacing IC�s and transistors, use only specified silicon grease,. Remove all old silicon when applying new silicon. 9. Before removing the anode cap, discharge eiecticity because it contains high voltage. 10.To adjust MCU N602 installed in the chassis, you should write master slice�s data into this MCU before installing, and no any data except this test manual listed is admitted to be modified without designer�s agree.
Test environment
1. Temperature: 15~35°C 2. Relative humidity: 45 ~ 75% 3. Air pressure: 86 ~ 106kPa
TEST EQUIPMENT
1. DC Power Suply (14V) 2. Oscilloscope 3. High Voltage meter 40KV 4. Multi-meter(internal resistance:DC�20kΩ/V,AC�5kΩ/V) 5. Ammeter(0.5 grade,DC3mA) 6. Degaussing Coil 7. PHILIP Picture Signal Generator(PH5820 or other type)
