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!

3.1 EEPROM initialization Enter the first page of factory menu, select �clear eeprom� and then press �enter�, shut down the unit after �ok� appears. 3.2 VGA/DVI channel adjustment 3.2.1 Preset VGA channel mode Input VGA signal (PATTERN 5: Final Test) of K-7253, select TIME301(640*350/70Hz), press �AUTO� to do the auto adjustment until the screen is filled with picture. Use the same method to do auto adjustment for the following items: TIME302 (720*400/70Hz) TIME303 (640*480/60Hz) TIME311 (800*600/60Hz) TIME313 (1024*768/60Hz) TIME315 (640*480/75Hz) TIME316 (800*600/75Hz) TIME317 (1024*768/75Hz) TIME319 (1280*1024/75Hz) TIME339 (1280*1024/60Hz) 3.2.2 ADC adjustment of VGA channel Adjust ADC-gain to 15. 3.2.3 White balance adjustment VGA/DVI channel Input K-7253 8 level gray-scale signal of TIME311 and PATTERN474, enter white balance adjustment menu; adjust the third and seventh levels using white balance. Select 6500k of �mode�, adjustment offset_R, offset_G and offset_B, let the color coordinate of the third level be 308 and 316 and its brightness be 16nit more or less. Adjust gain_R, gain_G and gain_B, let the color coordinate of seventh level be 308 and 316. Adjustment offset_R, offset_G, offset_B, gain_R, gain_G and gain_B repeatedly until the value of the two levels gray-scale be 308 and 316. Select 9300k of �mode�, adjustment offset_R,offset_G and offset_B,let the color coordinate of the third level be 285 and 290 and its brightness be 16nit more or less. Adjust gain_R,gain_G and gain_B, let the color coordinate of seventh level be 285 and 290. Select 12000k of �mode�, adjustment offset_R, offset_G and offset_B, let the color coordinate of the third level be 270 and 283 and its brightness be 16nit more or less. Adjustment offset_R, offset_G, offset_B, gain_R, gain_G and gain_B repeatedly until the value of the two levels gray-scale be 270 and 283. Note: gain_R, gain_G, gain_B is value not above 128 and let its value 128 at least. 3.3 Adjustment TV channel 3.3.1 Adjustment VCO, OPTION, sub-brightness and sub-contrast Input AV color bar signal (PM5518 COLOR BAR 100%) to VIDEO 1 terminal, enter the first page of factory menu, press �enter� selecting �auto color�, display �OK� after 2 seconds; then you can finish the VCO adjustment; set the value of �option� to 10, �Hor-width� to 32 and �s-bright� to 140 as well as S-contrast to 140. set the MaxVolume according to its product standard. 3.3.2 white balance adjustment of TV channel Input AV signal (PM5518, NTSC system, 8 level gray-scale signal), enter adjustment menu of white balance, adjust the third level and seventh level using white balance. Adjust offset_R, offset_G and offset_B to let color coordinate of the third level be 270 and 275 and its brightness be about 21nit. fixate gain_B to 128, adjust gain_R, gain_G to color coordinate of the seventh level be 280 and 280. adjust offset_R, offset_G,offset_B, gain_R and gain_G, repeatedly using the same method until 4
