I bought a Sanyo a little over a year ago. All was well until recently. The red color started to disappear and now I only have mostly green and blue. I bought another Sanyo and it seems to be playing ok. I was going to replace all my tv's with Sanyos but now I am afraid to.
What call I do?
Thanks so much,
Darlene Paris Pipkin

Just 'cos one Sanyo has started to act funny does not mean all Sanyo TVs are bad.
As for the defective Sanyo TV, it seems that there is some problem with the Red Output circuits.

Tries the broadcasting incomming signal cable,with another tv connected to see,if can get the red color,if no than,the imcomming the broadcasting cable it the problems.If yes,ur tv have a Tuner board problems,it dead.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish Tuner signal board for the replacement.
I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.
Problem solved. I tried playing DVD and the TV picture was fine. So I double-checked cable wires from cable box - one of the wires was loose (obviously it was the red color input). After tightening, the TV picture is good as new.
I would check the green signal all the wat to the display screen to determine is this is a signal problem or a system short. I would recommend that you take this set to a qualified electronics technician
