There are several fuses on the power supply board.

The main one is right next to where the cable from the AC connector is on the power supply.

BTW you may want to check these listings too:

(although if you are looking for a fuse that probably means totally dead TV and if that;s the case then you do not need a main board repair)

SOURCE: Sanyo DP42740 tv turns off and on by itselfl It


Unplug the TV for few minutes, say 30 minutes and then turn it ON. If it still does not work,it confirms an internal failure. The main cause on this model is ' power supply board '. Other than this, even the faulty boards could cause the same problem. The TV has to be opened, carefully inspected and then the part has to be replaced. If you have electronics repair experience, could read schematics, would be able to use multimeter and could keep all precautions, revert and i could tell you where you could buy a cost effective service manual and would provide you few pointers that would help you to fix this problem.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Sounds like you have a bad digital reception from the aerial. You'll either need to adjust or replace the aerial, make sure all lines are connected at the aerial point, and it's advisable to invest in a signal booster.

SOURCE: How do we hook up

Hi Amy,

I cant see any specific connections for your tv but the end of the cable from your wii will have either a 21 pin sc"scart" connection or 3 plugs,(red, white and yellow) Look about on the back of the tv for corresponding socket. There should only be a couple of choices for each. Then simply plug it in. There will be no tuning or anything to do as these are direct connections. On your tv remote look for a button which will display or select the direct inputs. May look like a small screen shape with an arrow pointing into it, or may say "ext" or similar.
Hope this has been helpful

SOURCE: fuse location for a 50" sanyo tv

The fuse should be located on the power supply board. You'll have to remove the back cover to access it. I posted a link of what the board should look like.

Sanyo dp42740 tv shuts off and on still has picture and sound

Two places are suspect---one is the manual on/off button on the set--actual button may look ok but it is common to have the momentary switch under it be bad in this way.

Second area to suspect is the power supply inside the set switching on and off because of a defect there or the control circuit that turns it on and off.
