I don't know what Sanyo's policy is now but used to be they would not sell you any kind of service documentation. That was back in the 80's and I stopped buying any Sanyo stuff after that.

Documentation is seldom a problem. Anyone with a little intelligence
can locate schematics on the internet. My favorite source is
elektrotanya.com. Scribd often has documentation, even training
manuals for some models.

In the case of backlight / inverter failures, the service manual is
seldom useful. In most cases the tcon and the inverter are considered
part of the panel and are not documented. Again, all it takes is a
little creativity to troubleshoot these.

Hi!
I have a Sanyo HD TV Mdl DP32746 that has good sound no picture and
no light on the screen, should I guess the back light inverter or the T Con
board.
Thank you for any help you can give me.

It's most likely the inverter, but there is a quick and easy test to
help decide. Working in a darkened room, turn the TV on. Does the
screen get lighter, even momentarily? With the back of the TV off, do
you see any lighted areas on the back of the lcd panel?

Googling the model number indicates the TV has a history of inverter
failures. Checking eBay finds that there are LOTS of tcons available,
only one inverter.

A brief flash on the screen indicates an inverter or CCFL problem; if
the backlights never come on it's most likely an inverter problem,
often a fuse.
