My apologies if this is in the wrong section, I did not notice a repair section.
I have a pioneer pdp-5016hd it was having an issue with the red color realm. It would basically no display the whole color spectrum correctly and some shades would show in a bright red orange color. This went on for about 4 months and no it is not displaying red at all anymore.
I am a HT installer so I am sure it is something internal and not a connection issue. It does this one all possible inputs.
Any idea on what it would likely be?? X or Y drive??
I am in chicagoland if anyone knows of a honest tech shop
