Question about Sanyo Televison & Video
I've got a Sanyo DP15647 that suddenly stopped working. It displays a pretty green light when the power button is pressed. But nothing else. I checked it out and both the power board and the main board appear good visually, no bulging capacitors or anything like that.
I've got a multimeter and I checked all the cables they're fine, and I've tested the connectors on the board. I was wondering if anyone more familiar with LCD screens could suggest some other things to try to find the point of failure so I don't replace unnecessary parts.
Any input appreciated!
I had a similar problem like yours with a different TV. I had to find the Service Manual for the TV to really find the problem. The manual gives me every schematic and parts number list for every board in the TV.
It turned out to be a bad Inverter Transformer. It was one of six that powered the LCD screen. You might have the same problem.
The Service Manual on the internet for most TVs are under $20. It's the best material for diagnosing the problem. It worked for me.

These are the instructions which worked for me on my Canon pixma mp470:
1) Close the print head cover, and turn off the printer. While pressing the Resume/Cancel button, press the Power button. (Do not release the buttons. The LED lights in green to indicate that a function is selectable.)
2) While holding the Power button, release the Resume/Cancel button. (Do not release the Power button.)
3) While holding the Power button, press the Resume/Cancel button three times, and then release the Power and Resume/Cancel buttons. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.) During initialization, the LED blinks in green.
4) When the LED stops blinking and lights in green, press the Resume/Cancel button the 4 times. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.)
5) Press the Power button. The LED lights in green, and the
selected function is performed. (When the operation completes, the printer returns to the menu selection mode automatically.)
6) Power off then back on and test.
