Everything was ok with the manual. If I have a small complaint, is that I ordered it during the weekend and I think you guys were closed. But I did receive it late Sunday. I will surely order from you again
Best Service! Very fast and easy to handle. Fast Download an you can come back every day to download again
Very good quality, no parts are missing and everthing is readable.
Thank you very much. :-)
This manual is all I need to check and repair my equipment. Thank you....
sorry for my english...the service given by O.M.com is perfect for content and codition...!!!
thank's a lot!!!
No. Adjustment point 1 Tuner IFT ( PRESET ) Adjustment condition/procedure 1. Get the tuner ready to receive the CH. E - 9 signal,but with no signal input. Adjust the PLL data. 2. Connect the sweep generator's output cable to the tuner antenna. ( RF SWEEP ) 3. Adjust the sweep generator's to 80dBÂµV. 4. Connect the response lead ( use LOW IMPEDANCE probe with wave detector ; see Fig.1 ) to the tuner's IF output terminal. ( This terminal must have the probe alone connected ). 5. Set the RF AGC to 0 - 6 V with no saturation with the waveform. 6. Adjust the tuner IF coil to obtain the waveform as shown in Fig. 2. Note: Be sure to keep the tuner cover in position during this adjustment. Waveform or others
No. Adjustment point 1 PURITY ADJ.
Adjustment condition/procedure 1. Receive the GREEN-ONLY signal. Adjust the beam current to ~700 ÂµA. 2. Degauss the CRT enough with the degausing coil. Note: Follow the Job Instruction Sheet to adjust the magnetic field. Vertical Bv: +0.030 mT (0.30 gauss) Horizontal Bh: +0.020 mT (0.20 gauss) (Reference: page 7-2) 3. Maintain the purity magnet at the zero magnetic field and keep the static convergence roughly adjusted. 4. Observe the points a, b as shown in Fig. 1-1 through the microscope. Adjust the landings to the A rank requirement. 5. Orient the raster rotation to 0 eastward. 6. Tighten up the deflection coil screws. Â» Tightening torque: 108 Â± 20 N (11 Â± 2 kgf) 7. Make sure the CRT corners landing meet the A rank requirements. If not, stick the magnet sheet to correct it. Note: This adjustment must be done after warming up the unit for 30 minutes or longer with a beam current over 700 ÂµA. Note: Set the service mode by JA304 & JA307 (short) then press factory process R/C RGB key to change to RGB mono colour mode. * For the following colours press R/C RGB(Hex 7E) key to change. Waveform or others

RF-AGC TAKE OVER POINT ADJUSTMENT (I2C BUS CONTROL) (AUTO & MANUAL ADJ)
1. Receive "PAL COLOUR BAR" signal. Â» Signal Strength: 56 Â± 1 dBÂµV (75 ohm open) 2. Connect the oscilloscope to TP201 (Tunerâs AGC Terminal) as shown in Fig. 3-1.

* for Auto ADJ 1)Receive âPAL COLOUR BARâ signal. signal strength: 56 Â± 1dBÂµV(75 ohm open) 1)Go to service mode. 2)Go to service data V01, press R/C to operate auto key (Hex C1) and confirm the âOKâ display on the screen. 3)If appear NG, increase data some step and pls repeat step 2 again. 4)proceed step 4 & 5 in manual mode.

3. Call "V01" mode in service mode. Adjust the "V01" bus data to obtain the Tuner output pin drop 0.1~1.0V below maximum voltage. 4. Change the antenna input signal to 63~67dBÂµV, and make sure there is no noise. 5. Turn up the input signal to 90~95 dBÂµV to be sure that there is no cross modulation beat.
