Dear Sir,
Document is original service document of sharp. I had a problem with the door contacts. Fuses where blown. With the manual in a few minuts is was clear what the problem was.
Manual was of great help.
With kind regards,

The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

let's say first that i do not need to have a credit for my opinion, i am a retired sparkie and i voluteerd to fix an electronic device for a local "Youthgroup",as no diagram was present i checked the "net" and gambled on this site and paying some fee via PayPall, i was gladly surprised that the manual arrived as was stated, GOOD SHOW, and best wishes, John
3. TROUBLESHOOTING
3-1. Test Mode is not activated With the set assembled in the front panel, the Test mode does not become active if any button was pressed by any reason.Under this condition, the power is not turned on even in the normal status. (The set is kept in Standby status = Red LED is kept on) Not only the buttons are inactive, but also a signal from remote commander is not accepted. To check this condition, with the self check port (pin wh of IF CON) kept in �Low� status, supply the AC power, so that the Test mode is forcibly activated. On the board, short the lands where SELF is printed. The IF CON checks the self check port only after the power on reset (only when AC is supplied; not in Standby status). If any button was pressed, the button name should be displayed on the FL display tube. Though no button is pressed this time, display of other than NOTHING implies that the button was pressed. 3-2. Power is not turned on 1 Red (STANDBY) LED does not light up when AC was supplied. The power (PDET=5 V) is not supplied. X401 is oscillating. 2 Red (STANDBY) LED is kept on though POWER button was pressed. Any button is kept pressed. PONCHK (IF CON pin 6) is over 0.1 V. 3 Green LED lights up when POWER button was pressed, but red LED lights up again after several seconds. PONCHK (IF CON pin 6) is abnormal. (Slow rise time from 0.1 V to 2.5 V. Voltage must be less than 2.5 V) SYSTEM CONTROL does not operate normally. 3-3. Power is turned on and off repeatedly EVER 5 V may not be supplied normaly. Check that P301 (MPW1240/MPW1311) is not broken.
