Find out the model / chassis and give a better description for the problem in order to get better help.

switch it off for 10 seconds .. then press button TV/AV
its probably due to power fluctuation ..
if the problem occurs check for local warranty service or service center

First, you need to know the sub-model of your TV.

It is called "chassis" and is shown on the back of the TV on the label where the model number is shown.

For example it can be "P42849-00" or "P42849-01".

Then search at www.coppelltvrepair.com/search or just go to www.coppelltvrepair.com and enter the link for SANYO DP SERIES to search for that.

Here's an example of a repair service (note it may NOT be the one for your exact model though!):
