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.
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.
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.
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 âCD-râ at this point.
20 7 IC401
Note 1: If the TOC cannot be read, âERRâ has appeared on the LCD. The following step 2 and 3 can be verified even if the âTOCâ cannot be read. Note 2: By repeatedly pressing the DISPLAY/ENTER button all the LCDs light up and the âTOCâ display is repeated. Note 3: By repeatedly pressing the DSL button the LCD âCD-râ and âCD-dâ are repeated.
When the LCD displays âCD-dâ â¢CD-DA, CD-R is selected. When the LCD displays âCD-râ â¢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)
This mode enables you to perform a confirmation of the disc distinction. Confirmation method Press the DSL button and select âCD-dâ or âCD-râ (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
LCD displays âCD-dâ LCD displays âCD-râ No disc No disc CD-RW CD-DA and CD-R
* All numerical values are displayed in HEX.
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.
