Colors are skewed on Pioneer Pro-520HD

It is probably in need of an alignment, which is pretty typical for rear-projection TVs. Try calling a TV technician.

Have you attempted to adjust the brightness setting?

The most common issue on this model is the power board develops all kinds of bad solder connections--have to remove and in most cases hand solder the entire board.

through HDMI it should be able to im not sure but you can go to

search-the name of your (tv-Pioneer PRO-520HD-specs) the specs should let you know if you can or can't but most likely you should be able to

No,this tv 100% have convergence problems,it dead.Any colors lines R,G,B are mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must be replaced to solved the tv pictures convergence problems.The shop,will cost u like $300-350 for parts and labors.

U can't tv have parts problems.Ur tv have a problems known as a convergence problems,it dead.Tv have colors lines R,G,B mis alignment anywhere in the picture,have picture colors shadows or 3D pictures look like.The tv have 2 STK convergence ICS and some or all it resistors are dead.These parts on the tv convergence board,must be replaced on the tv convergence board to solved the tv convergence picture problems.The Shop,will cost u like $300-350 for parts and labors.

The problem could be a few things, check your color balance and contrast or try adjusting the guns. If its a fuzzy red haze, kind of like a halo around things, it may just be that the crt coolant fluid needs changed. I, myself, have had a problem with the tinted halo in my rear projection Toshiba tv, I replaced the crt coolant fluid and the picture returned to good as new.

Not familiar with this particular model but it should have a convergence menu. If so, try using the convergence menu (which is basically a cross pattern (possibly multiple ones) that you use as a reference to align your colors and make the cross pattern white. When you go to this menu and see the cross patterns, if you see the shadowing of the colors, you will know what I'm talking about. If this adjustment(s) don't work, you may have a problem in your convergence board circuitry. Wish I could be of more help but try the menu.....I've fixed 2 or 3 sets like this now. Good luck!

need mor info the tv when turn on after 15 or 30 minuts works fine ?
