reasonable price for the schematic - the service is perfect, all as expected and pointed by instructions - good scan of the original plans - thank you!
;
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.

3 CCD (IC802) A charge-coupled device in which charges are introduced when light from a scene is focused on the surface of the device. The image points are accessed sequentially to produce a television-type output signal. Effective picture element: 249,936 = 508 (H) x 492 (V) PHIS1 ~ PHIS4: Clock pulse for the storage. PHI1 ~ PHI4: Clock pulse for the image pickup. PHIH1 ~ PHIH2: Clock pulse for the horizontal shift register. PHIR: CCD analog signal output.
