At the upper left and lower right corners of the screen there is a red shadow. In the menu I cannot adjust the red in these areas. it is a full cross out of alignment.

Problem #1) Convergence

Symptoms:

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted
  • No Audio/Video - makes a chirping sound.

EZPRO 610H...has a red shadow


this is ghosting, caused by interferance. cheaper cables tend not to have metal sheathing and those ferrite RF suppression thingees on the ends, which prevents this problem.

also, avoid running your signal cables next to power cables. If your cables are long (say more than 10m) this may also cause problems.
