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!

In a word AWESOME.
I never expected the quality and abundant content that I got with this manual. Everything you'd ever want to know from a service perspective is found in this manual, along with... as a bonus, operating instructions on how to use the unit. WOW. Very impressed with the quality of the manual. You won't be disappointed if you're looking for the EVS900 service manual.
Alignment and Adjustments
4-3 Other Adjustments
4-3-1 General
1. Usually, a color TV needs only slight touchup adjustment upon installation. Check the basic characteristics such as height, horizontal and vertical sync and focus. 2. The picture should have good black and white details. There should be no objectionable color shading; if color shading is present, perform the purity and convergence adjustments described below. 3. Use the specified test equipment or its equivalent. 4. Correct impedance matching is essential. 5. Avoid overload. Excessive signal from a sweep generator might overload the front-end of the TV. When inserting signal markers, do not allow the marker generator to distort test results. 6. Connect the TV only to an AC power source with voltage and frequency as specified on the backcover nameplate. 7. Do not attempt to connect or disconnect any wires while the TV is turned on. Make sure that the power cord is disconnected before replacing any parts. 8. To protect against shock hazard, use an isolation transformer. If the chassis or parts of the cabinet become magnetized, poor color purity will result. If this happens, use an external degaussing coil. Slowly move the degaussing coil around the faceplate of the picture tube and the sides and front of the receiver. Slowly withdraw the coil to a distance of about 6 feet before removing power.
4-3-3 High Voltage Check
CAUTION: There is no high voltage adjustment on this chassis. The B+ power supply must be set to +130/155 volts. (Full color bar input and normal picture level). 1. Connect a digital voltmeter to the second anode of the picture tube. 2. Turn on the TV. Set the Brightness and Contrast controls to minimum (zero beam current). 3. The high voltage should not exceed 33KV. 4. Adjust the Brightness and contrast controls to both extremes. Ensure that the high voltage does not exceed 33KV under any conditions.
4-3-4 FOCUS Adjustment
1. Input a black and white signal. 2. Adjust the tuning control for the clearest picture. 3. Adjust the FOCUS control for well defined scanning lines in the center area of the screen.
4-3-2 Automatic Degaussing
A degaussing coil is mounted around the picture tube, so that external degaussing after moving the TV should be unnecessary. But the receiver must be properly degaussed upon installation. The degaussing coil operates for about 1 second after the power is switched ON. If the set has been moved or turned in a different direction, disconnect its AC power for at least 10 minutes.
4-3-5 Screen Adjustment
1. Turn to the ACTIVE channel. 2. Adjust the VR screen for a normal picture is (no blooming or flyback line).
3. Adjust the FOCUS control for well defined scanning lines in the center area of the screen. 4-6 Samsung Electronics
