Schematy są ale można wysilić się i zrobić kolorowy skan i o większej rozdzielczości. Wtedy schematy płytek będą czytelniejsze. Całość super jako wartość merytoryczna. Wszystkie dane potrzebne do podłączenia różnego rodzajów urządzeń takich gramofon, CD itd.

Szybko, sprawnie i tanio. Serwis godny polecenia. Będę polecał innym

Ogólnie jest OK, z wyjątkiem obrazu płyty głównej, który jest miejscami mało czytelny, ale można sobie poradzić.

Dokładna dokumentacja, pomogła w szybkiej naprawie telewizora. Dziękuję!

jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
Test Screen
Test Screen
When you press the TEST button on the front panel or on the remote you can activate a still image to test all settings and the video performance of your TV. With the vertical color bars you can test the following: I proper color intensity setting on your TV, I the proper color of each bar, showing if the proper video standard is turned on: the colors should be (left to right): black, white, yellow, cyan (turquoise), green, magenta (purple), red, blue, black. I proper color transition, seen as sharp separation of the bars, S-Video will be better than Video, RGB best of all. I the performance of the color filter in your TV (with �Video� signals), bar edges should show no vertical crawling dots. Here S-Video and RGB formats usually give no problems. With the grey scale and the black/white fields below the color bars the brightness and contrast of your screen can be adjusted optimally, see chapter �TV Picture Adjustment� below.
TV Picture Adjustment with Test Screen
These adjustments may be done now, but you can also make them after setup has been finalized. They can also be made at any time when the player is in Stop or Resume mode, simply by pressing TEST on the remote control or on the front panel. Brightness adjustment: 1. Turn down the color control on your TV until the color bars are visible in black and white. 2. Adjust the contrast to the lowest level where you still can see all bars within the grey scale in the test picture separately and clearly. 3. Adjust the Brightness so that the bars in the grey scale are all visible. The bar furtherst to the left has to be as black as possible rather than grey but the next aside must clearly be differable. All the bars in the grey scale have to be gradually and evenly changing from black to whiter, going from left to right. Contrast adjustment: 1. Adjust the contrast on your TV until you see a bright white bar in the right low corner of the screen and a deep dark black bar at the left. The optimal contrast setting will depend from your preference and the surrounding light in the TV room. 2. If the brightness of the white bar will no more increase while turning up the contrast or when the borders of the white �harman/kardon� text letters on top will bloom (overlight) into the black areas, what drasticly will decrease the sharpness of the script, then the Contrast has been turned up too much. Reduce the contrast until these effects will disappear and the video still looks realistic. 3. If you are watching TV with a usual surrounding daylight, adjust the Contrast so that a normal video picture has about the same looking as the surroundings in your room. By that way the eye is relazed when watching the TV picture. This contrast setting may be reduced when the surrounding light is dimmed, usually improving the sharpness of a video a lot thereby. 4. The grey scale in the middle line needs to have the same clear difference between each bar as before the contrast adjustment. If not, go back to the brightness adjustment and repeat step 3 and then the contrast adjustments, making only minor adjustments each time for optimisation.
Color adjustment. 1. When the Brightness and the Contrast are set optimally, turn up the color control to the level of your perference. Adjust to the level where the colors look strong but still natural, not overdone. If the color level is too high, depending from the TV used some of the bars will seem wider or the color intensity will not increase while the control is turned up. Then the color control must be reduced again. At the end you should test the color intensity also with a video, e.g. pictures of natural faces, flowers, fruit and vegetables and other well known natural articles of our life most usefull for an optimal setting of the color intensity. 2. If your TV has a Tint option (with most European TVs this is available or effective only with NTSC signals, not with PAL), use the large white bar below the Greyscale to tweak the warmth of the picture. Every viewer has a difference in preference as how the glow of the picture should be. Some prefer a little colder picture, some a warmer glow. The Tint function on your TV and the white bar can be used to control this. Adjust the Tint to the level where you feel the white color has the tone you prefer.
