- Very good scan quality, PERFECT!
- Sehr gute scan Qualitaet, empfehlenswert!
Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++
Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.
I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you
Manual was reasonably easy to follow. I am not an engineer or know much about electronics but with the manuals help I was able to figure out the problem, identify the part required for the repair. Replacement part cost around $30. Whilst replacing the part I was telling myself, "this aint gonna work cos it seems far too easy". Took about 15 minutes to do and my plasma TV works a treat. Would never have been able to do this without the service manual.
No. Adjusting point 1 115V adjustment: R711 Adjusting procedure/conditions 1. Receive the Monoscope Pattern signal. 2. Set to the P-NORM mode. 3. Connect a DC milliammeter between TP602(â) and TP603(+). 4. Take the beam ammeter reading to make sure that the beam current is between 900 ÂµA and 1100 ÂµA. * If not, readjust the FBT screen control to obtain the beam current of 900-1100 ÂµA. 5. Connect a digital voltmeter to TP701. 6. Adjust R711 so that the digital voltmeter should read 115 Â±0.5 V. Waveform and others No. Adjusting point 1 VCO adjustment: T203
Adjusting procedure/conditions 1. Disconnect the antenna from the tuner antenna terminal. 2. Apply DC voltage to pin (4) of IC201 (IF AGC). Â» DC voltage: 6.0 V (allowable +0.1 V) 3. Using a digital voltmeter, measure the DC voltage at pin (20)(PLL FIL) of IC201. * The digital voltmeter must be able to take readings down to the third decimal place. 4. Relieve pin (4) of IC201 of the DC voltage. 5. Reconnect the antenna in position and receive the E-12CH signal. (With the AFT off, adjust the receiving frequency to 224.25 MHz.) 6. Connect the DC digital voltmeter to pin (20) of IC201. Adjust T203 so that the voltmeter should read the same voltage as in Step 3. Allowable error : 0.015 V (20 kHz) 1. Receive the PAL Colour Bar signal. If this signal is not available, any signal above the E-5CH band is acceptable. Â» Field strength : 55-80 dBÂµV Make sure the frequency is almost the same as that of the received channel (Â±30 kHz). 2. Using the channel setting control, make a frequency of 224.25 MHz appear on the screen (the AFT turns off). If any other channel than Colour Bar is received, make its frequency on the screen. (The AFT turns off when the on-screen display turns yellow.) 3. Turn T204 clockwise to have a 6V point, and counterclockwise to have a 0.2V point. Position the coil at the center of these two points. 4. Adjust T204 so that the DC voltage at pin (1) (AFT OUT terminal) of IC201 be 3.3 Â±0.1 V. (See Fig. 3) 1. Receive the PAL Colour Bar signal. Â» Field strength : 57 Â±1 dBÂµV (75 ohms open) 2. Connect the oscilloscope to TP210, as shown in Fig. 4. Oscilloscope TV Set + TP210 0.1V â Bias box
Waveform and others * Warm up the unit for longer than 10 minutes in advance.
* 10 kHz at about 0.007 V.
* Position the T203 core in the range in which the Colour Bar signal can be received.

No. Adjusting point 1 Tuner IFT (preset): TU201 Adjusting procedure/conditions 1. Get the tuner ready to receive the E-9CH signal. but with no signal input. Adjust the PLL data. 2. Connect the sweep generatorâs output cable to the tuner antenna. (RF sweep) 3. Adjust the sweep generatorâs output level to 80 dBÂµV. 4. Connect the response lead (use a low-impedance probe with wave detector; see Fig. 1) to the tunerâs IF output terminal. (This terminal must have the probe alone connected.) 5. Set the RF AGC voltage to 0-6 V with no contact with the waveform. 6. Adjust the tuner IF coil to obtain the waveform as Fig. 2. shown in Note: Be sure to keep the tuner cover in position during this adjustment. Waveform and others

3 RF AGC cut-in adjustment: R216
C â 1.5dB Â± 0.8dB
Fig. 4 Â» Bias box: About 4.5 V 3. Turn R216 to have the highest voltage. 4. Turn R216 slowly in the opposite direction until the voltage goes down 0.1 V below the highest level. 5. Adjust the signal level to 63-67 dBÂµV and make sure there is no noise. 6. Now adjust the signal level to 90-95 dBÂµV and make sure there is no chrominance modulation beat.
