    Nothing but green & reds on screen. Tried adjusting everything under the menu for video settings, but nothing works.

    I have a SONY BRAVIA KDL-46S2010 I bought approx 2+ years ago. Occasionally, after I change the channel, the picture turns green&purple and can only get normal color again by turning TV off and on again. Have had no other problems...What's going on?? Bought it from Best Buy and it's now out of warranty.

    My Bravia KDL-40S2000 is exhibiting the same think. HD channels are just fine. Other digital and analog channels display human flesh tones in purple and eyes of green.

    It seems like the TV has to be on for quite a while (be warm or hot) before this problem occurs. Turning the TV on off and on doesn't seem to help.

    I have a Sony BRAVIA KDL-46V25L1 (same as KDL-46V2500, I think, the only difference is it was sold at Costco). When the TV has been on for a few minutes (not all that long), and I am watching High Definition channels, then, if I switch down to the low definition channels, the colors change to only green and purple. The only way to correct this is to shut off the TV and then turn it back on. If I happen to go back to HD again and then back down to low def, same thing. Other than this issue, the TV is great, crystal clear colors and HD channels are perfect, we have been very happy with it. This strange purple / green only issue started about a month or so ago. Luckily, I have a month left before my one-year warranty is up. I am returning it to Costco for a refund... I don't want to be left having the TV if turning off and on stops correcting the color issue. And its kind of embarassing when company is over and they are flipping around the channels.....

    I have a 37" 1080p toshiba lcd and a charter hd cable box. I use the the dvi output on the cable box and im using a dvi-to-hdmi cable to connect to my tv. Ive had the tv almost a year and i recent started having the purple and green color problem with standard definition channels. HD channels, dvds, video games, etc. work fine. If i unplug the hdmi cable from the tv and plug it back in the problem goes away. Reseting the cable box and/or turning the tv off and on again do not fix the problem. Im having charter replace my cable box in a few days ill post again with my findings

Subsequent to my Nov 14 2008 posting... shortly thereafter, I had returned my Sony BRAVIA KDL-46V25L1 (KDL-46V2500) to Costco. Then, (after trying a 52" Samsung, whose picture was nowhere near as good as Sony in High Def , but that is another story) I purchased a newer (one year newer) Sony BRAVIA KDL-46W4100 with 120 Mhz refresh rate.

What did I find?

The same purple/green image problem (“The Problem”) exists in the newer model Sony as well ! !

I believe the actual issue is with the TV, not the cable box, in that the TV contains faulty logic in in the way it handles switching from one input format to another. Turning the TV off and back on ‘resets’ the TV, and corrects the TV display (at least in the case of my Sony BRAVIA KDL-46V25L1 (KDL-46V2500) and Sony BRAVIA KDL-46W4100).

That action should have little impact on the cable box output.

My Shaw High Definition cable box has two output options for HD: Component RGB, or a DVI output. It came with an RGB cable, and a DVI / HDMI cable (DVI end for cable box, HDMI for TV).

When I use the Component RGB, my TV does not have “The Problem”; everything is fine with all the various cable box output settings I have tried.

When I use the DVI / HDMI cable, I get the “The Problem”.

“The Problem” only appears under one specific set of conditions as noted below....

My cable box can be configured to handle output for standard definition (SD) channels in one of four different formats: Nothing, 480i , 480p, or STRETCH. (where ‘Nothing’ lets the signal pass through as-is ).

ONLY when the cable box is configured to send SD channels as 480i does “The Problem” arise.

The TV has an issue (bug in video logic?) handling the switch from 1080i to 480i, only when using the DVI / HDMI cable between cable box and TV.

IE “The Problem” only seems to occur while using both the DVI/HDMI cable, AND when the cable box channel is changed from a high definition 1080i channel to a standard definition channel AND the cable box is set to convert the output of the SD channel to 480i .

By changing the cable box to send SD channels as ‘Nothing’, or 480P, or STRETCH , and “The Problem” goes away.

Or, using the Component RGB cables, and “The Problem” goes away !

Hope this helps.

I've seen this same switching HD-normal tv color issue problem before, and not just in sony LCD, also in toshiba and mitsubishi as well, same case scenario, DVI (cablebox) to HDMI input (TV), wayching HD channels, you go to a normal channel, and then in between the switching you have the color issue.
I think that the software/ firmware in the cablebox, is the cause of the problem, and some microprocessors in the tvs are sensible about this. Samsung is the only tv that is not as sensible as the brands mentioned above, this does not means is a better brand.
The problem happens just using the DVI output and nothing else. Solution: TV is not the problem, replace cablebox with a HDMI output.

I had the same problem with my SONY LCD TV. I have 5 cables (green, blue, red, white and one other) connected to the back of the TV. I removed all 5 and then reconnected them. The problem was resolved.

My lcd tv has a purple screen and no sound

same problem all set to replace TV but tried another source DVD instead of dish and it was fine. Possible the cable (cheap HDMI) but reboot the dish (hard) pull the plug and fixed it up, probably the HDMI connection at the source or the TV (or the cable)

The color seems to be off. No red, and lots of purple. This is a Toshiba 57H81 wide screen big box tv. It was purchased in 2002.

Could be a bad board within the tv but it is sometimes the source input meaning it could be dvd player, cable/satellite box, etc causing the loss of color but it is unlikely. I have one of these tvs and they use red green and blue projectors to reproduce the colors so when the red projector fails then you get purple which is green and blue colors combined without the red. I have found it to be sometimes a bad connection inside the tv and I found insects such as roaches inside others. Using extreme caution when opening the rear cover of any tv due to dangerous and fatal high voltage. You might find that simply cleaning out the inside of tv and reseating all the connectors might resolve your issue otherwise you would have haul this tv to a repair shop where you pay half the price of a new flat screen lcd for just repairing this tv which will probaly have another color go out next month.

Red Color not working

Does this only show up in one connection IE: HD cable box, DVD player etc, If connected to a HD cable box a loss of red can mean a defective red component cable.

Color changed suddenly, no red, just green/yellow/blue

Sounds like the color wheel has gone bad and needs to be replaced. This is located behind the back panel.

Color problem with TV

Are you getting Green or purple or pink patches all over the screen?
This could be a problem of Degaussing. Have you placed any Magnetic source near the TV recently? Some Tape recorder or walkie talkie or a Speaker, etc? The Magnetic field created by any of the above sources can cause coloured patches over a colour TV screen.
It also happens if you shift the TV from one location to another.

The third possibility is that the Picture Tube's Red Output stage gone faulty. Unless you are a trained Solid state Electronics Technician, there is nothing you can do. Better go for a trade in.
