No picture or sound. Power board led flashing in sequence of 12. Says D12V on legend.

No video but audio is fine on Sanyo 42" DP42746 TV


If you unplugged the Ysus board, then you need to replace the Ysus board, or both sustain boards. This is the part: The part is often available on Ebay, or from manufacturer. Look also at Vance baldwin or Partstore. To do a good job the Sustain boards should be tested by a tech , following service manual. It is almost for sure sustain board by the way.

Sanyo dp42746 low volt power problems


The power supply is failing, or there is another circuit area that is pulling too much current, and the supply is going in to protect mode.

This would require proper troubleshooting by an experienced tech. If the problem is very involved, or the tech is not familiar with the set, he will require the service manuals and service information.
