Question about Sanyo DP42746 42 in. Plasma Television
I saw that you posted on a couple of topics about Sanyo dp42746 42" plasma tv's. I was wondering if you had any advice on where to obtain a service manual for this set?
The only source would be Sanyo. They can refer you to their parts sales rep for your area.
Just to make a suggestion, there is not much you can service in these sets. Some of these service manuals can cost upwards of $60 to $150 depending on the manufacture and model.
Servicing at the component level without the training, extensive diagnostics systems, jigs, and tools is mostly impossible unless it is a simple obvious fault. These sets are extremely complex in their assembly and design.
At the service centers they service these sets by board and module swapping. These sets are basically serviced like as if it was a PC computer. They have the basic calibration setups to calibrate replacement boards when necessary. Sometimes the new boards have to be matched.
I also found that if the set is more than about four to five years old it is sometimes impossible to have replacement boards. The technology turn-over is very fast with these flat panel TV sets and monitors.
