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.

It is OK, this manual help me to repair my dynacord

Good manual. Even it is an old printed manual, it is well scanned and complete, with all drawings, schematics and parts list. Very good return for the cost.

I'm very satisfied with my purchase. It resolved my problem. Owner-manuals.com is a very very good place.
Thank you!
TEST MODE
The servo circuit of this model is designed to be adjustment-free and the adjustment value and disc distinction (CD-DA, CD-R and CDRW) etc. is adjusted by the IC. Therefore the adjustment is performed at each TOC reading. The adjustment conditions in the IC of each servo can be monitored in this test mode.
1. How To Start The Mode
OPEN/CLOSE SW SHORT LAND VC
Starting method of the test mode differ depending upon the type of disc being used. This is because the adjustment values of each servo also differ depending upon the type of disc. When using the CD-DA or CD-R 1) Short-circuit TEST LAND and OPEN/CLOSE SW land. 2) Insert the AC plug to the power outlet and install the CD-DA or CD-R disc. 3) Press the PLAY and STOP buttons in this sequence and read the TOC.
TE
S303
FE
IC502
When using the CD-RW 1) 2) 3) Short-circuit the TEST LAND and OPEN/CLOSE SW land. Insert the AC plug to the power outlet and install the CD-RW disc. Press the PLAY, STOP and DSL buttons in this sequence and read the TOC. The LCD should display �CD-r� at this point.
20 7 IC401
IC501
Note 1: If the TOC cannot be read, �ERR� has appeared on the LCD. The following step 2 and 3 can be verified even if the �TOC� cannot be read. Note 2: By repeatedly pressing the DISPLAY/ENTER button all the LCDs light up and the �TOC� display is repeated. Note 3: By repeatedly pressing the DSL button the LCD �CD-r� and �CD-d� are repeated.
RF
When the LCD displays �CD-d� �CD-DA, CD-R is selected. When the LCD displays �CD-r� �CD-RW is selected. Note 4: The test mode is canceled by disconnecting the AC plug and remove the soldering of short land.
2. DISC distinction (confirmation of the FE waveform)
IC451
IC601
This mode enables you to perform a confirmation of the disc distinction. Confirmation method Press the DSL button and select �CD-d� or �CD-r� (Refer to Note 3). 1) Install the disc. 2) Press the MODE button. The LCD will change as follows: Example: Test disc: TCD-782, DISC type select: CD-d Judgment value: 68, Measurement value: 37 CF
IC701
68
61 IC301
37 CF
Measurement value
LCD displays �CD-d� LCD displays �CD-r� No disc No disc CD-RW CD-DA and CD-R
* All numerical values are displayed in HEX.
Judgment value
What disc the IC has selected can be understood according to the judgment value. The decision standard of IC is as follows.
0 < Judgment value < 10
No disc CD-RW CD-DA and CD-R
TEST MODE SHORT LAND
10 < Judgment value < 32 32 < Judgment value < C8 C8 < Judgment value
The state of the FE waveform can be also understood from this judgment.
