Three Green spots and one purple one on screen.

The set if projection which model here is, has arced and now each of the three picture tubes used has a tiny permanent burn mark on its screen.

That is what you are seeing, the set uses three picture tubes with screens like the old tv sets===the coating has been burnt in each, want to prove it, remove rear cover and cover any one of the three lens and that mark on one tube will go a way.

Not fixable.

This is along shot but you may have picked up a virus a few months ago, do a full system scan, also download malwarebytes anti-malware and do a full scan, if nothing shows up consider a full windows operational install, I have found in some cases it fixes the video problem.

The colored spots may be a light engine issue that Panasonic will pay for repair costs even though tv is few years old. Contact Panasonic. . No you can't reset the lamp timer without a remote.

Does your model end with a "5" as in PTnnLCX65? If so call the Panasonic call center to schedule service or find a servicer, they have a fix for colored spots on the 2005 MMDs ending with the number 5. The fix is being coverd under warranty.

Kevin,

for the color problem,most likely you do have problem with loose contact of components from C-board ( small board connected at the back of CRT "picture tube" which drives every color and size of the screen)if you have knowledge with soldering electronic component parts, resolder this board and also check main board for possible loose contact.

cheers,

I have the same issue with the WD-52528. I was told it may be a bad light engine. Service is coming out August 27th. I'll let you know what they say.

How old it the P tv

hi

if you see a purple spot on the picture screen, it may have been magnetized.

what you can do for that is find a demagnetizer so get rid of the purple spot.

you can purchase that at any electronics shop.

hope this helps.

you have pixels going out my friend. No fix

Loss of green = purple!....Please give model # and age from
back of set ........T.
