I have a Mitsubishi WD82738 DLP TV which after recently switching from YouTube TV streaming to Spectrum cable with a TiVo, is displaying pink shadows over white colors on the screen. All the colors, including red, seem to be accurate. Just whites or very light blues have a pinks glow or shadow . Very annoying. Does anyone know if that is caused by a bad color wheel, or could it be an adjustment in the service menu?
Looks like loose or oxidised/dirty cabling. Open up the TV and find the flat cables that connect the mainbkard to the TCON board. Use a Qtip and contact cleaner to clean those. See if it gets rid of the problem.
