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.
