Was given this tv by a friend after he was unable to get it to stay on. It was his bedroom set and he said it was rarely ever used . I have read the 2 seconds to black threads but it acts a bit different . It turns on and acts normal for about 4-5 seconds then shuts down. The green power led does go out too . I'd like to get it going but I'm not really sure which board would be at fault ? Would it be the power supply board or the video board ? I assume it shutting itself off is some kind of fail safe mechanism ? Thanks for any help.

Ummm... I'd be checking the STBY and the PSon voltage and see what happens to them once the TV turns itself off.Comment

Could you be more specific on how to check ? I have both a digital and analog meter . What would be the correct voltages I'm looking for ?Originally posted by CapLeaker View PostComment

Re: Sanyo DP42647 2 seconds to black sorta...
post a nice sharp straight pic of your power supply and another one from the PSU where the wires go from it to the main board. We need to see the name of the pin outs.
STBY is usually 5V and that is always there on the PSU regardless if TV on or off. That goes to the mainboard and once you turn the TV on, a PSon signal (should be more than 2.5V) comes from the main board back to the PSU and turns all of the PSU on.
You have to figure out, if the PSon signal disappears or not.Comment
