Replacing the DM module. I would like to know price for this part. And what does this part do for the tv in relation to the picture. Tv has constant transparent black/purple verticle shading - each about 6" wide. Side by side. Also - tv has, what I call scratch lines, all channels. they roll, and tilt -- really bad picture. But pic can be seen behind all of this. Sound is fine. Tv is 5 yo.To date - replaced 1 bulb, and these issues started about 2 months ago. TV repair person says dm module will fix it all. Is charging $500 to install. Thank you Mike

If the caps on the DM board are not swollen on the top, they re ok, but if they are replace them.

Hi,
Check this link for guidance with pictures about DM board removal.
Thank you.

I just called customer support and my issue is now fixed, to my extreme surprise.

It sounds silly (and a tad embarrassing), but here's what I did:

1) Unplug the TV
2) Wait 30s
3) Plug the TV in
4) Test

Apparently even if the TV is "off" for a few days it never fully shuts down unless the power is unplugged. Not sure if this will help anyone else, but I had the exact same problem others are describing. Good luck!

See Here:

as well as in your manual. Sometimes the lamp must be reseated
by removing it and reinstalling it with great care making certain
the door and all the gaps are closed tight.

If the lamp replacement or reinstallation does not solve the
problem you will likely need a service tech to look at the tv
as there are few user serviceable items for Plasma sets. Most
of the repairs are done by computer connection that downloads
the error messages and interprets what went wrong.

Hope this helps.
