Manual was just as described!!! I odered it and in less than a day was able to download it and the text was clear and pages were all complete just as the original manual was. Purcashed this for a friend and they were more than happy. Perfect all around!

Excellent service and prompt delivery. But it's not a manual - only 4 pages wiring diagrams.
Thanks.

The manual I purchased was exactly what I needed to repair my Toshica television. The manual contained schematics and troubleshooting information that was very helpful.

The Service Manual was just as expected, complete with schematics and I was able to download it in less than an hour after I ordered it. The only problem with these is that the schematics are hard to read due to the small font. I could remedy this by printing them on a larger printer.
The servo circuit of this model is designed to be adjustment-free and the adjustment value and disc distinction (CA-DA. CD-R and CDRW etc.) is adjusted by within the IC. Therefore the adjustment is performed by each TOC reading. The adjustment conditions within the IC of each servo can be monitored in this test mode.
1. How to start the Test Mode
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 the test land and the OPEN/CLOSE SW land. 2) Insert the AC plug and install the CD-DA or CD-R disc. 3) Press the PLAY and STOP buttons in this sequence and read the TOC. 4) Press the DISPLAY/ENTER button and confirm that all LCD light up. When using the CD-RW 1) Short-circuit the test land and the OPEN/CLOSE SW land. 2) Insert the AC plug and install the CD-RW disc. 3) Press the PLAY, STOP and DSL buttons in this sequence and read the TOC. The LCD display should display CD-r at this point. 4) Press the DISPLAY/ENTER button and confirm that all LCD light up. Note 1) If the TOC cannot be read, press the DISPLAY/ENTER button once �Err� has appeared on the LCD, causing all the LCDs to become lit up. The following steps 2 and 3 can be confirmed even if the TOC cannot be read. Note 2) By repeatedly pressing the DISPLAY/ENTER button, all LCD will light up and the TOC display will be repeated. Note 3) By repeatedly pressing the DSL button, the �CD-d� and �CD-r� displays will be repeated. 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 cancelled by disconnecting the AC plug and removing the soldering of short land.
2. DISC distinction (confirmation of FE waveform)
This mode is possible to perform a confirmation of the disc distinction. Confirmation method 1) Press the DSL button and select �CD-d� or �CD-r� (Refer to Note 3). 2) Install the disc. 3) Press the MODE button. The LCD will change as follows. Example: Test disc: TCD-782, DISC type select: CD-d, Judgement value: 7F, Measurement value: 3D BE.
Judgement value
Measurement value
*All numerical values are displayed in HEX What disc the IC has selected can be understood according to this judgment value. The decision standard of IC is as follow. LCD displays �CD-r� 0 < Judgment value < 10 10 < Judgment value < 32 32 < Judgment value < C8 C8 < Judgment value LCD displays �CD-d� No disc CD-RW CD-DA and CD-R No disc No disc CD-RW CD-DA and CD-R
The state of the FE waveform can also be understood from this judgment value.
3. Confirmation of sled movement
By pressing the F. SKIP or B. SKIP button continuously when all LCD light up, it is possible to transfer the pick-up to either the outer circumference or the inner circumference (the LCD is to remain all light up).
