SOURCE: Sanyo DP15647 powers on but no display, trying to find fault

I had a similar problem like yours with a different TV. I had to find the Service Manual for the TV to really find the problem. The manual gives me every schematic and parts number list for every board in the TV. It turned out to be a bad Inverter Transformer. It was one of six that powered the LCD screen. You might have the same problem.
The Service Manual on the internet for most TVs are under $20. It's the best material for diagnosing the problem. It worked for me.

SOURCE: 50 inch Sanyo Vizon Plasma TV. Has sound but no

This set has LG insides, it will have failed on either the Y-Sustain PCB or the Z-Sustain PCB.

Quite common.

Repair estimates should be $250 - £350 depending on which has failed.

Stick it on eBay, it will fetch good money faulty.

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.

What cable do i need to connect my laptop to my Sanyo DP50740?

Hello jaygee7414,
Sanyo DP50747 not support for D sub conection (PC in).
To connect PC in, you can use DVI or HDMI input.
Some Laptops already have HDMI or DVI out put. Like HP mini, sony vaio.

Or you can use s-video input.
