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.
