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.
See the adjustment location from on page 23 for the adjustment.
