I'm always surprised at how inexpensive the service manuals are when I have to buy one from the manufacturer. Last time was for a stereo receiver and they charged me $12. Before that was a television and that only cost $16. So, contact Sanyo and buy there service manual.
What, inexpensive? How much can you ask from the customer for repairing his old CRT TV? Near nothing, otherwise he will buy a new one for that price. Imagine buy the SM, components, waste your time. If you are buying the SM for money, is impossible to make an economical deal.
The customer just needs to look at the 3rd world country that the new TV is made in to see why it is cheap and doesn't last long. It also will not be repairable.
