Complete and very useful. Could have benefited from a little higher resolution on the schematic and layout diagrams for improved legibility.

This manual is complete and very readable.It was a great help for my two ICF5800L.The first one had the dial cord broken,and without the service manual it is impossible to replace it.Thank.Olivier.

This is a top quality manual. You couldn't get better if you had the original and scanned it yourself. Best price on the net as well. Diagrams are clear and complete, text is sharp and easy to read. Granted you don't get the manual the second you click pay, but the few hours you have to wait for it to be available for download isn't a problem at all. This is a very reliable company.
Very VERY pleased with the product, and will buy others. Thanks!

Brightness Control
1 — Color Tuner: TU200 TEPE5-02 Selects a desired radio wave and changes it to the video IF signal. 2 — Video IF Amp.: Q200 2SC4238 Amplifies the video IF signal output from the tuner TU by 10 times (20 dB). 3 — 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. 4 — Audio Amp.: IC600 NJM2070M Sound amplification. 5 — Chroma Circuit: IC300 M52045FP Generates the tricolor (red, green, and blue) from the video signal. 6 — Osc./A-D Converter/Display Control/ Auto-Tuning Control : IC700 MSM6625-01 GSK-640E Converts the color signal into a digital signal. Also, generates the clock pulse for the display and controls the display. 7 — Tuning Voltage Generator: IC500 MSC1169MS-K Generates the tuning voltage with the tuning pulse (TU) output from 6. 8 — Display Voltage Generator: IC800 BA10358F, Q800 ~ Q806 Q810 Q811 2SD1149-S, 2SD601A-R×3, 2SB709A-R Generates the display voltages V0 ~ V4 with VEE1 and VCC7 outputs from the power supply.
