SOURCE: Have a Sanyo Plasma TV

Hello,

Yep. The power supply in Sanyo Plasmas are generally prone to failures. It could be a failure in the panel not priming, but I doubt it. Turn the lights off in the room, then try to turn it on. If you see the screen faintly flash, the panel is priming, but it is not coming on. If the screen is lit, but is still "black," then it is a control or digital board. If it is totally black with no light at all, then it doesn't entirely rule out the first two, but makes a power supply failure more likely.

They usually have a lot of heat damage to them. If you have tried unplugging it for 15 minutes, then plugging it back in and it still doesn't work, the it is most likely a secondary in the power supply.

I hope this helps you...

SOURCE: The sound just suddenly quit on my Sanyo model

Test the preamp outputs - audio/line out - of the TV to be tested on an amplifier . If there is sound then the fault is with the power amplifier within the TV. If not there is fault in the SIF- sound IF and preamap.
To trace you will need to use a signal trace and injection with a voltage check on the output IC. If absent check for open fusible resisitors or if this burns out the IC is short and must be replaced. Check also the speaker.

SOURCE: sanyo dp50747 powers on but no picture or sound

There is an internal fuse if could be blown. If the fuse is good you might try reflowing the solder on the power board.

Sanyo DP50747 50" Plasma sound but no picture green light is on.


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
