    Sanyo 40" LCD TV color & AV imput problems

    Sanyo 40" LCD TV color & AV imput problems
    My Sanyo 40" LCD TV has been having problems with color flaring in dark pictures face's and other arias flare red not all the time sometimes the picture is fine like new, but under certain conditions sometimes worst than others very noticeable sometimes in commercials when the screen is all orange or red the left side of the screen from top to bottom 3" wide flares yellow or white,the red flaring happens threw out the whole picture not solid bits here and there, it reminds me of the old picture tubes as guns went bad but not just around not the edges, Is this a board that can be replaced I have experience repairing these sets as far as switching out boards changing bad caps any help at all would would be appreciated, Second problem in the past week i'd be watching TV and the screen would go blank for about 30sec then come back on and in the upper right corner in a blue block it says video 1 like what comes up when you change video input setting this happened 2 times a day now it will sometimes happen every 45min then once a day again and back and forth I have FIOS TV and wondered if it may be the box, what do you think, you guys helped me out before and I was able to repair both sets I the highest confidence in you a deepest respect Please any help at all will be appreciated Thank You Very much for your anticipated help Needles (Bill)

    No model number, no pictures of the boards and the pictures of the whole backside of the TV to see how all the boards are connected together? We have no idea what we are dealing with.

          At least show the screen shots of what you are seeing on the screen.

              There is no need to apologise. As you can imagine it is difficult, near impossible to service at a distance on an unknown set which is why photo's of the circuit boards and of the symptons are an important start in order to help. Pictures are worth a thousand words.

              Hopefully you can get some help at which time you will be in a position to post what you can. Once again no apology needed.
              Willing to help but I'm no expert.
