Thanks God for the internet and thanks for the service like this - proffessional solution on time.
;
About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

The downloaded quality was as good as the orignial

This is a great and complete Service Manual for the Sharp GF8585HB. Giving full and detailed technical insight. Good to find these manuals online.

Everything was ok with the manual. If I have a small complaint, is that I ordered it during the weekend and I think you guys were closed. But I did receive it late Sunday. I will surely order from you again

Increase three steps of MAT CONT adjustment value of OFFSET-RGB1. OFFSET mode: Select the RGB 1 mode by top and bottom keys MAT CONT : 1 key Increase three steps of adjustment value by right and left keys. Increase two steps of MAT BRIGHT adjustment value of OFFSET-RGB1. OFFSET mode: Select the RGB 1 mode by top and bottom keys MAT BRIGHT : 2 key Increase two steps of adjustment value by right and left keys. Turn ACL SW setting to ON. INITIALIZE mode ACL SW : 3 key Select ON by right and left keys. Input a RGB (PC) signal to INPUT1 or INPUT2. A signal pattern is only luminance signal such as lamp signal and a STEP signal. And use the signal which black level (0IRE) and gradation can confirm. � Recommended signal: VESA VGA@60Hz

Turn to standby once, and perform power supply ON with the factory mode once again. MENU � SET � POWER ON Take a trigger of oscilloscope with HD_PLL (3.3Vp-p) of K4805. Measure the signal waveform of Green signal at K4603, and measure the black level (0IRE) of signal and signal amplitude. AD R LOW adjustment Measure the black level (0IRE) of Red signal at K4602, and adjust so that the level of AD R LOW to match the black level (0IRE) of Green signal which measured with step 10 of video signal. Adjustment error: ± 0.05V OFFSET mode: Select the RGB 1 mode by top and bottom keys AD R LOW : 9 key Adjust by right and left keys. AD R HIGH adjustment Measure the signal amplitude of Red signal at K4602, and adjust so that the level of AD R HIGH to match the signal amplitude of Green signal which measured with step 10 of video signal. Adjustment error: ± 0.05V OFFSET mode: Select the RGB 1 mode by top and bottom keys AD R HIGH : 6 key Adjust by right and left keys.
