Where is reset button on sanyo 50 inch tv model DP50740 The TV will not stay on


There is no reset button on televisions. I see that is a plasma set, if you are just losing the picture that is one thing, if the whole set is shutting down, that is another. Please advise

It clicks on then clicks off


It sounds that the TV switches ON, and switches OFF, after three relay clicks. It is likely to the fault to its main board. Contact any service technician. This is not a user repairable fault.

Dp50740 power led goes on and off


What you have is most likely a failed main board. These sets are known for this problem. There are several different variations of the main boards. Make sure you order one that matches yours. The main board part # will start with J4@#. The main board part # should be on a sticker either on the main board itself or on the coax input terminal casing. I hope you got the TV for a good price !!!

Sanyo dp50740 will not come on after power surge is there a reset?


Connect TV to a different power outlet and try. Switch off TV manually, remove plug from power outlet after switching off power, and retry after 48 hours. If problem persists, it might need attention by a qualified service technician.
