complete part-lists and pcb layout, schematic diagram is good enlargable,
Excellent, fast delivery, excellent product. Good luck!
This manual is for the usa model only. But it is clear
, accurate and comprehensive, including board layouts and schematics.
I found it extremely useful for my mitsubishi dp-86da, but the same diagram would also work for the realistic lab5000 and hi fi 80. Thanks.
Great to have extra resources for Service Manuals, Now days you can really not trouble shoot efficiently without one , Wayne at IRIONS TV & ELECTRONICS REPAIR Clearwater , Fl. 33755 727-446-7955
For five bucks you can barely buy a hamburger. Or for the same five bucks you can buy a service manual. Much more useful. (and better for your health, depending on where you buy your hamburgers).
Yes, there are free manual sites out there, but if they don't have what you want, you have to pay.
And five bucks isn't much. Not for full specs, schematics and adjustment and parts replacement procedures.
My only criticism is that grayscale illustrations aren't well rendered, but I've seen worse.
Schematics and text are clear.
I'll be happy to purchase from here again.
6.1.3 MD Mechanism Assy Adjustment and Check
1 Temperature Check (Please perform this check soon after the power has been switched on.)
Note: When IC101 (RF-AMP) or IC104 (mechanical controller) has been exchanged or when a correction changing VD+3 has been made, be sure to correctly perform all steps up to step 7.
Step No. 1 Operation Keys and Operation Method Short circuit MECH TEST MODE during the power ON, or press the ESC key. (Service remote control unit)(Fig.1) Press the REC key. When is 80 or more at this time, the adjustment is OK (step 4 and following can be omitted). is 80 (not passed) Measure the ambient temperature T (Â°C) andcheck hat the measuring value ( ) is within the standard in regard to the microcomputer set value ( ). Note: When the indication of the measuring value ( ) is not stable, and the ambient temperature T (Â°C) is 25 Â°C or less, set to the lower value. When the ambient temperature is over 25 Â°C, set to the higher value. TEMP 80 FL Display EJECT Test mode Status Remarks

Step No. 1 Operation Keys and Operation Method Short circuit MECH TEST MODE during the power ON, or press the ESC key. (Service remote control unit)(Fig.1) Press the SET key (Remote control unit) Measure the laser power with an optical power meter. At this time, check that the measuring value (PLAY power) meets the standard value of the table on the right. Note: When the standard value on the right is applied, the numerical value immediately after entry into test mode 2 shall be taken as the standard.
