Long story short: Red Sparkling Dots on Plasma TV a.k.a Red Snow, kind of like "hell vision" may be caused by incorrect voltage if cause is not interference, cabling etc.


EDIT: SOLVED: Simply unplugging and plugging the DA5 cable [see attached picture] fixes the red snow problem.


After you open up the TV and read this: please click here

If you want to check if Vsus is 193 Volts,


You get the Service Manual. Locate the Test Point locations, please click here

So now if you put the RED part of the Digital Multimeter on the Test Point, where does black go... where is ground for the circuit?

• 3. Is there ground next to TP15V, click here

Use the Mounting screws and pads for GND.
It's right in front of u.

 

When I attach the digital multimeter test probes like this: click here

I get no change on the display: click here

 

I just got it:

When I make contact with RED to the green tip on the picture, I got a 15V reading and a 192V reading on the TPVSUS which means it's perfect, moving on to other test points.

 

Results:

I know it's not the cables because red snow appears with multiple inputs, even VGA input. It could be power related.


Vset was 249V vs specs: 260V +/- 7V but I don't think it's that, there is no way to adjust that that I can see.


Results here.

 

You decided it is an adjustment fault that your set gives red snow.

It faulted Just like that ?.

 

This is a problem that some Plasma TVs develop. Sometimes it's connections and power issues, but often the voltage is the problem. When the red snow issue is permanent, people didn't even measure voltage, they just adjusted the values until the red snow was gone.

In my case I only have intermittent appearance of red snow flashing around. It happens with multiple connections so if voltage is not the issue - it may be a power issue or faulty board, I don't know.
