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.

Good manual. Even it is an old printed manual, it is well scanned and complete, with all drawings, schematics and parts list. Very good return for the cost.

� Color Tuner: TU200 TEPU5-02 Selects a desired radio wave and changes it to the video IF signal. � Video IF Amp.: Q200 2SC4238 Amplifies the video IF signal output from the tuner TU by 10 times (20dB). � Video Det./Sound Det./FM Det./AFT/AGC: IC200 M51348FP Eliminates the carrier wave in the video IF signal, and picks up the video signal and the sound IF signal. Also, the sound signal is picked up from the sound IF signal by FM detection. � Audio Amp.: IC600 NJM2070M Sound amplification. � Chroma Circuit: IC300 M52042FP Generates the tricolor (red, green, and blue) from the video signal. � OSC/A-D Converter/Display control/ Auto-Tuning Control : IC700 MSM662502 GSK-640F Converts the color signal into a digital signal. Also, generates the clock pulse for the display and controls the display. � Tuning Voltage Generator: IC500 MSC1169MS-K Generates the tuning voltage with the tuning pulse (TU) output from 6. � Display Voltage Generator: Q800 ~ Q806 2SB1218A-R, 2SD1824R, S � 2, 2SD1819A-R � 5, 2SD1824-5 Generates the display voltages V0 ~ V4 with VEE1 and VCC7 outputs from the power supply.
