Sanyo DP50747 - powers on for seconds then off

[halobender]

Hey all was hopping through some posts here looking for some info on this Sanyo DP50747. Can't seem to locate a thread with the same issues.

Standby led functions. Turn set on a light on possibly the control board blinks and after 6 seconds or so the set turns off. It will allow me to turn it back on but has the same issues.

Checked all fuses. All good. No physical telltale signs of bad caps. Anyone have a service manual or some ideas of what to check?

Thanks

Is this a LED or CCFL backlight LCD TV?

Check the voltages on the diodes page 5

Some photo's of the circuit boards and layout would be helpful.


Download service manual
