Sanyo DP32746 Power Supply

When I press the power button on my Sanyo DP32746 I can hear the power relay pull in. After 10 seconds the relay drops out. During the 10 seconds the relay is in, there is no picture (screen stays dark) or sound. After attempting to power up the set 3 or 4 times the relay stops pulling in all together. If I unplug the set for a few minutes and plug it back in I can get the relay to pull in again for 10 seconds. I realize the relay is dropping out as a protective measure. Has anyone had this problem and been able to resolve it? Is there a particular module that I can replace to get the set working again?

Sanyo DP52449, tv getting power but no display

When DP52449 (chassis 01 - that is important!) does not power on and the front LED flashes every 15-20 seconds you have a faulty main board, which you need to replace or get serviced.

We presently do not offer replacement boards, but we do offer repair services for them at

You may also be curious to read the article we wrote back in July 2012 on a problem that sounds exactly like yours and which lead to the service offerring:

Hope this helps!

When i hit the power button it clicks like it wants to turn on but the screen does not come on

It sounds like the back light inverter board may have gone out, or it is not getting 24vdc from the power supply module, those are the two places to check.

Sanyo DP32746 - No picture or Sound

Damage is in the power supply. I am an authorized tech for Sanyo, and in the Chattanooga TN area. Contact Sanyo at 1-800-877-5036. At the prompt hit the 0 key, and then ask for customer service. They will be more then happy to assist. If your set is to old for warranty service, and you wish to repair yourself, check out the site, they can provide functional pwb's for a fraction of the cost of new.

Check the power cable and power socket. If they are working, and the indicator lights in the tv do not light up when connected to power, that means the PSU (Power Supply Unit) is faulty. Take it to a repairer.
