I have a 32" Sanyo TV that I purchased in May 2005.
My problem is with the color. The reds, blues, yellows and greens are like neon -- very, very bright -- and it is hard to get any definition. I tried manually changing the color, unplugging the TV for an hour, and pressing Reset, but nothing seems to help. Do you have any ideas?

Need to know if older set with picture tubes---turn color off--if yellow screen you have a loss of blue of some sort--red and green will give you a yellow screen. If set has the 3 picture tubes look inside in the lens to see if all 3 have a image---little or no blue means a problem there.
hi" do you try to adjust color settings.theres a red,blue,green color adjustment under picture setting.
try to set red color to full. of you already do that. probably your display driver board has a causes the problem. display driver board produce image comes from the tuner, then it sent to x and y drive of your LCD screen.
The solder joints on the CRT board might have cracked and cause this symptom. What you are describing indicates that the red gun is intermitten, and the solder joints on the CRT socket itself (red cathode) or the red output transistor have probably cracked loose.
Are the yellow, red & white cables RCA phono plugs?
Yellow = Video
Red = Right Audio
White = Left Audio (mono)
The red, blue & green cables are for picture only and don't include sound. Have you tried using the red, blue & green for the picture and using the other cable, red & white for just the sound? Don't use the yellow.
On mine I took the rear cabinet off, unseated the card mounted on the picture tube, applied a little dielectric grease on the connector on the card and reseated the card, removed, re-greased and reattached the card. I have had no problem with either my or mom's which I did the same to since! This is an easy fix that anyone can do. The hardest part is moving the TV and reassembling the rear cabinet. Do not pull the cabinet back out more than you have to, to ease the reassembly of it.
