I Have a plc-sw35, Gave me many issues (switching off etc..) Ive managed to repair it, and made the manual available. http://www.entwan.netau.net/1_8_Repair-Schematics.html
My repair story is there also.

In the on-screen menu...
Press MENU, go to SETTINGS ICON, Move to Lamp Reset
Also, to see lamp hours used, press and hold the UP ARROW (on the unit, not on the remote) for 30 seconds while projector is on.
There are 2 possible causes.
The first may be due to overheating. Most projectors have a "air filter" that can be removed and cleaned. If it gets clogged with dust over time, the projector can't breathe and shuts down.
The second cause may be your lamps life hour clock. Most projectors keep track of the amount of time that their bulbs have been active. Once a preset # of hours has passed the projector will limit functionality until a new bulb has been installed AND the lamp life clock reset. Most projectors do not automatically reset the lamp life clock after a new bulb is inserted.
There should be instructions on how to reset the lamp clock in your users manual, and info on cleaning the air filter. Unfortunately I went to the Sanyo website and was unsuccessful in locating a PDF of the user manual for you.
