- Very good scan quality, PERFECT!
- Sehr gute scan Qualitaet, empfehlenswert!

Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++

Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you

Manual was reasonably easy to follow. I am not an engineer or know much about electronics but with the manuals help I was able to figure out the problem, identify the part required for the repair. Replacement part cost around $30. Whilst replacing the part I was telling myself, "this aint gonna work cos it seems far too easy". Took about 15 minutes to do and my plasma TV works a treat. Would never have been able to do this without the service manual.

Step 6: DIR A
A
Check that the S/PDIF signal is output. Check that changes by pulling out and inserting the digital input lines. IC601 (pin 1) IN1 (OPT: TV/SAT)
IC952 (pin 14) Do convert 3 V into 5 V for pin 6 input? Yes IC952 (pin 13) Do convert 3 V into 5 V for pin 7 input? Yes To Step 5
No Replace IC952.
Can No Check the DIGITAL INPUT Assy, observe the digital signal and parts and patterns in the path. ? (0 V <-> 4 V) Yes IC601 (pin 5) IN2 (OPT: CD-R/TAPE/MD)
B
No
Replace IC952.
Can observe the No Check the DIGITAL INPUT Assy, digital signal and parts and patterns in the path. ? (0 V <-> 4 V) Yes IC601 (pin 44) Can observe the digital signal ? Yes IN3 (COAX: DVD/LD)
Step 5: X'tal
IC802 (pin 2)
C
No
Check the parts and patterns in the path.
(1.65 V center, amplitude more than 0.2 Vp-p) IN4 (COAX: CD)
Is there a 24.576 MHz output? Yes IC802 (pin 7)
No Replace IC802 or X801.
IC601 (pin 42)
Can observe the No Check the parts and patterns digital signal in the path. ? (1.65 V center, amplitude more than 0.2 Vp-p) Yes No Check the path to pin 45 of IC801. Replace IC802. IC601 (pin 27) Is there a master clock output? No Check the path to pin 30 of IC601. Replace IC802. MCKO2 (Master clock) Check that the data and clock signals are output.
Is there a 24.576 MHz output? Yes
D
IC802 (pin 5)
Is there a 24.576 MHz output? Yes To Step 6
Is the No voltage of PDN IC601-pin 31 5 V? (0 V <-> 3.3 V) Check the other assy. (surrounding of the Yes microcomputer) No No Replace IC601.
IC601 (pin 24)
LRCK (LR clock)
E
Is there a LR clock output? Yes
No Replace IC601. (0 V <-> 3.3 V)
