The process involves activating the Service Alignment Mode (SAM), configuring specific display settings such as white tone levels, contrast, and brightness, and utilizing an oscilloscope to measure cut-off pulses on the picture tube cathodes. It includes precise instructions for identifying the correct cut-off pulse and adjusting the SCREEN potentiometer on the Line Output Transformer (LOT) based on screen size specifications provided in the included reference tables. This maintenance documentation is essential for technicians performing accurate display drive alignment to ensure optimal picture quality and component longevity. The guide concludes with instructions for restoring normal user settings after successful calibration.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/philips-l011e-vg2-alignment-procedure/561007/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/philips-l011e-vg2-alignment-procedure/561007.png","ImageObject",300,407,{"name":92,"@type":93},"Adam","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-21","2026-10-12",true,{"@type":102,"interactionType":103,"userInteractionCount":24},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What are the initial brightness and contrast settings required for the alignment?","Question",{"text":112,"@type":113},"Before starting the adjustment, set the CONTRAST to zero and the BRIGHTNESS to the minimum level, where the OSD is just visible in a dark room.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How do you identify the cut-off pulse during measurement?",{"text":117,"@type":113},"When measuring the signal on the cathode with an oscilloscope, you will see two pulses; the cut-off pulse is the one with the lowest value, appearing during the first full line after frame blanking.",{"name":119,"@type":110,"acceptedAnswer":120},"What is the correct cut-off voltage for a 27-inch screen?",{"text":121,"@type":113},"For a 27-inch screen, the cut-off voltage should be adjusted to 145 ± 10 V according to the provided reference table.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},561007,1792144394,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":29,"category_name":30,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":24,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":8,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":143,"read_time":81},1374404737137,"https://ap-avatar.wpscdn.com/davatar_155a257f0dc6eb9ab79c44ca47cae57d","PHILIPS L01 . 1E  \nVg2 Adjustment  \n1. Activate the SAM.  \n2. Go to the WHITE TONE sub menu.  \n3. Set the values of NORMAL RED, GREEN and BLUE to.40.  \n4. Go, via the MENU key, to the normal user menu and set  \n– CONTRAST to zero.  \n– BRIGHTNESS to minimum (OSD just visible in a dark room) .  \n5. Return to the SAM via the MENU key.  \n6. Connect the RF output of a pattern generator to the antenna input. Test pattern is a'black' picture (blank screen on CRT without any OSD info) .  \n7. Set the channel of the oscilloscope to 50 V/div and the time base to 0.2 ms (external triggering on the vertical pulse) .  \n8. Ground the scope at the CRT panel and connect a 10:1 probe to one of the cathodes of the picture tube socket (see diagram B) .  \n9. Measure the cut off pulse during first full line after the frame blanking (see Fig. 8-2) . You will see two pulses, one being the cut off pulse and the other being the white drive pulse. Choose the one with the lowest value, this is the cut off pulse.  \n10.Select the cathode with the highest VDC value for the alignment. Adjust the Vcutoff of this gun with the SCREEN potentiometer on the LOT to the correct value (see table below) .  \n11.Restore BRIGHTNESS and CONTRAST to normal (=31) .","cbCaipvdQl0A5hsv","https://ap.wps.com/l/cbCaipvdQl0A5hsv","pdf",30467,"English","# Vg2 Adjustment Procedure\n## Calibration Steps\n## Technical Specifications","[{\"question\":\"What are the initial brightness and contrast settings required for the alignment?\",\"answer\":\"Before starting the adjustment, set the CONTRAST to zero and the BRIGHTNESS to the minimum level, where the OSD is just visible in a dark room.\"},{\"question\":\"How do you identify the cut-off pulse during measurement?\",\"answer\":\"When measuring the signal on the cathode with an oscilloscope, you will see two pulses; the cut-off pulse is the one with the lowest value, appearing during the first full line after frame blanking.\"},{\"question\":\"What is the correct cut-off voltage for a 27-inch screen?\",\"answer\":\"For a 27-inch screen, the cut-off voltage should be adjusted to 145 ± 10 V according to the provided reference table.\"}]","Philips L01.1E - Vg2 Alignment Procedure | PDF",1791804730]
